There are some other cool people on jewtube. I remember one guy talking to a guy on the other side of the world over ham.
I'm a noob who only has a rtlsdr dongle to listen.

write down the callsigns of local people who suck and ignore them. old fags think they own the air waves and get a power trip from bullying new users. it's the same shit as the internet; go on any forum as a new user and the dorks with 10,000 posts will try to get you to leave.

So you're saying rather than hanging back and getting a feel for the repeater/forum/channel/image board before you jump in and make a dick of yourself, it's best to just jump in and make a dick of yourself? Do you often elbow into public spaces you are unfamiliar with and start spouting shit, then blame the locals for not tolerating your special snowflake opinions?

I'm >>1298167 not even a hamfag, I just understand how communities work. No wonder you're so fucking jaded, you must be sick of being wrong.

Op you have to wait for some local event. Listen to the California Hams talk about the fire, or the next Happening fire up a broswer that feeds ham channels, and police chatter, while shitposting on /pol or /b.

Secondly, you don't need a license to ham during an emergency.

>>1298288
>it's best to just jump in and make a dick of yourself?

of course not. but the bitchers do have a point about "that asshole with 10000 posts" who ruins a board because he's built up his little fan club that supports him even as he posts incorrect crap, and I suppose some ham radio groups could occasionally suffer from that sort of deal where there's an established pecking order with jerks at the top.

but as someone said, move on if a community sucks that much. and if they all suck, maybe I'm the problem after all.

Was in totality of eclipse, same group of oldfags harumphing about "all the excitement; I'll just sit here in my hamshack and wait for it to be over; but don't clog the airwaves talking about it, never know what might happen." (clue: it's happening now dumbass).
During latest St. Louis riots, no one on the ground doing an AMA or even talking about it; oldfags are all in the county.
Anyway, seems like HF users are different from VHF users, and I'm sure I'll find a place to shitpost on the air. For those of you who are going to chime in after me about how airwaves are primarily for emcom not for shittalk, please explain the vast emptiness of the 220 band or Smitty's extensive diatribe on the best boiled peanuts. Until some young guys get on the air and start breathing some fresh blood into the bands, they are going to be filled with autistic geezers whining about "all these young guys with their computers."

>>1298288
according to OP, he didn't jump in and make a dick of himself though. he announced his callsign and "listening" which is common courtesy when you're listening to a channel as a licensed ham. it lets the people on the public repeater know that there's another person willing to speak if they're willing to have him.

but like most old hams, they prefer to pretend they own the repeater and are gatekeeping the people who use it.

>>1298288
>rather than hanging back and getting a feel
Did you not read OP?

>>1298149
Ok if you were on an HT. You will eventually understand why they were trying to help you with your signal. It's like 3 people standing around talking and some guy walks up and tries to join in whispers everything. You try to be polite but it's really frustrating. You can't hear how weak you most likely sound compared to everyone else. If you stick around long enough especially after Christmas you will be on the other end.

Also if you don't like chatting with geezers, sell your stuff now. Ham is an aging community. They are also mostly conservative and a LOT of conspiracy theorists. Just have fun and chill

>>1298361

It's like the ham equivalent of someone joining a forum with a badly optimized JPEG avatar saying "Hi" and then a bunch of senior members making fun of him in the thread.

I've listened to a few WebSDR's and i gotta say most of it is extremely boring old man talk. You get drawn in by the romantic thought of stumbling upon some pirate radiostation or spoopy numbers station late at night, but in reality it's just Geezer Club. The internet is a million times more interesting.

>>1298371
>Ham is an aging community.
Wait 5-10 years and all those old fagots will have died and their grandkids will have pawned the HAM equipment because grandpa was a dick and kicked everyone out of his hobby.

>>1298374
>It's like the ham equivalent of someone joining a forum with a badly optimized JPEG avatar saying "Hi"
No, it's sop when you are monitoring a repeater. Please go back to your websdr; you don't know what you're talking about.

Just passing through; no dog in this fight. I've seen ham threads in /diy/; I'm assuming these are young dudes. What do /diy/ hamfags do with radio? Listen to Alex Jones? Send clandestine coded messages? Listen to their neighbor's baby monitor? What?

>>1298659
>What do /diy/ hamfags do with radio?
it's like asking "what do you do with the internet?". on a daily basis, yea the most common thing is just listening or communicating. if you have an interest in diy electronics, you can use radio knowledge to create wireless projects. but it's a broad topic.

>>1298731
>yea the most common thing is just listening or communicating.

do people still send images? years ago, before the internet was widely used, I had a friend who was big into ham radio. He had a video display, and once in a while a picture of some ugly naked woman would trickle in over 10 or 15 minutes. Pretty sad, to be honest.

It's just neckbeard autists who are too fat to leave the house

>>1298149
ham is dead, it's just not been buried yet.

>>1298869
That's not entirely true, if there's a contest going on at least around here the airwaves light up like a Christmas tree.

>>1298149
Hamfag here. You need to get international qsos for interesting banter. Get a tall big antenna well tuned on 14mhz. Ignore American calls, try to get on at dawn or dusk. Germans and Russian stations are good chat, so is Scandinavian countries. Italy is loud and poor quality operation. Try Brazil and south America. Forget vhf and repeaters. I am happy to QSO with you to a schedule. Look me up LZ2ILR on qrz.com i often work over 5000 miles with 2 watts and a cheap diy antenna

>>1301283
OH A CONTEST?! WHOOP DE FUCKING DO.

a couple of hours of people frantically yelling CQ and their call signs and then nothing.

old guys on 40 meters talking about how much no one does ham radio anymore.

>>1303130
HF is for old guys who like spinning dials, repeating "CQ" over and over and over again, and mailing qsl cards.

All the cool kids are on digital systems now.

>>1303147
so, too, I hear, are a bunch of old guys who were once hams, downsized their living arrangements and thus had no space for antennas or a shack, and now gleefully spend their days chewing the rag on DMR making plans to meet up at a steakhouse the next county over

>>1298823
>do people still send images?

is that packet radio? i hear ham is one way you can still get a static IP address.

i have also watched some jewtubes of guys transmitting direct video.

>>1304437
There is more than one way to send images, but slow scan TV is probably the best-known. It isn't related to the packet radio.

>>1304437
> of guys transmitting direct video.

ATV. In some cases it's simply a matter of tuning a tv to them. The local repeater here was on 70 cm running a DAB+ output. Check the BATV website.

For a soon-to-be-licensed technician looking for a babby's first Tx rig for no more than 50 burgers and doesn't plan on much more than stroking the local 'peaters on 70cm and 2m, rarely operating mobile, any recommendations? Anything better than the baomeme UV-5RC for my purposes? I also have SDR at home.

Could someone talk me out of buying a used Motorola radio? I've used Motorola equipment at a few jobs and always appreciated how ridiculously durable it was, and kind of want a piece of Motorola gear for myself. The only issue I'm coming across is that a used 16 channel single band HT1000, antenna, battery, charger, and programming cable (I have an old Pentium laptop sitting around that will supposedly work to program it) will set me back just as much as a new Yaesu single band HT with more channels than I would ever need and the ability to program the radio without a computer (which would be nice for accessing repeaters while traveling), and if I was to get an MT2000 instead of the HT1000 it would set me back as much as a new dual band Yaesu (or a used single band mobile radio from one of the big 3). I still kind of want the Motorola radio, but I'm having a harder time justifying it given the other features I could get.

>>1298823
There's a guy in Colorado who regularly sends out communist memes on the SSTV frequencies, always funny to hear *DEDLEDEDLEDEDLEDEDLE* and then a minute or two later somebody starts yelling about socialists.

>>1306608
It depends on your situation. The commercial set should be a lot less susceptible to out of band rubbish.

>>1307352
I'm generally not in RF dense environments though and the city I live in is rather small. Would the better filtering on Motorola radios make them better for misusing as a mobile radio vs a Kenwood/Yaesu/Icom HT? Come to think of it, I figure something designed to be abused may have a better duty cycle for transmitting at full power without burning up your finals/having the radio drop the transmit power significantly as well vs the rather low duty cycles of most amateur radio HTs when transmitting at full power.

>>1307503
One of the local hams runs a modern yaesu on 100% duty cycle fm for hours at a time but he has had to fan force cool the thing. Hams tend to rag chew more than than commercial speech but I guess the motos sometimes run data so....

>>1307504
>One of the local hams runs a modern yaesu on 100% duty cycle fm for hours at a time but he has had to fan force cool the thing.
That sounds like a mobile radio, and those do have significantly higher duty cycles than an HT (especially if you have one that's actively cooled). Also, it's quite possible he's not running it at full power if he's just trying to hit a nearby repeater.

>>1307699
Its full power at 75 watts. Yes its supposed to be a mobile set but it has an external fan mounted next to it on the pa.

No point running for two+ hours straight on a normal repeater as it would time out.

>>1307792
>Yes its supposed to be a mobile set
My post here: >>1307503 was about using an HT as an improvised mobile radio (ie. with a battery eliminator and an external antenna attached to your car). I wasn't talking about actual mobile radios.

HAm radio died when Timmy died (N6MZA). We (the k7Ij repeater club) were the bad boys of Ham radio. Possible movie script- seriously funny geek wars... Our enemies on the Mt Diablo repeater were hilarious...one thing you need to know about Hams- they are literally usually uptight, ultra law abiding cop wannabes with a "license" that they seriously think makes them into junior g-men. The k7Ij repeater was the /pol /b of Ham radio- literally- including raids on enemy normie hams, electronic warfare (including directed energy weapons....) doxxing employers and getting people fired (this usually directed against us) We would license homeless people in Berkeley (so they could call 911 from their cardboard box) some of the incoherent rants broadcast on the Mt Diablo repeater were hilarious...Good ole days, if interested in the pinnacle of ham radio, look up N6MZA and K7IJ and mebbe me N6YSA

MY RE-TEST
I recently went back to San Diego,
making sure I steered away from the SDPD,
to meet Riley and retake the ham test.
I had no reason to study for I am a smart man.
I easily blurted out my answers
as my lovely wife read me the questions.
It took Riley about 5 minutes to grade my test.
He then looked at me,
and trying to keep from laughing he said
"You failed! You failed the NOVICE!
How can you NOT pass the novice!!??"
Well, I took it the second time and still did not pass.
I do not know when I will head back to San Diego
to try to get my ham license back.
This in N6MMMMMMMMMMM-Zed-A...clear.

How likely would I be to hear any activity on the amateur 2 meter or 70 cm band if I was adventuring in the middle of nowhere where there isn't cell service? I really want to play with this some more, but there's basically no activity in my city outside of one repeater (which still doesn't have much activity) despite there being a ton of coverage with one repeater covering both my city and another smaller city and another repeater in my city becoming part of a network in the near future that already covers an area of a few tens of thousands of people. Adventuring out in the middle of nowhere is pretty much the only thing I'm going to be doing outside of my city though. Are the VHF and higher amateur radio bands only good if you already have other people to talk to rather than trying to meet new people?

I have always imagined ham radio as being no different than 2 old men yelling back and forth "can you here me? How's the weather where you are?"

Over and over and over and over....

>>1308469
>"can you here me? How's the weather where you are?"
Not too far from the truth on some freqs.

And using q-codes on fucking voice freqs. Use fucking english you nerds.

>>1308480
Is that ham?

>>1308412
If you are going to work satellites VHF UHF may be ok in the middle of nowhere. We get occasional interstate activity on 70 but more often on 2 and 6 metres here. For true middle of nowhere work hf is the go with a selection of bands.

>>1308469
on days like today sometimes all you wanna talk about is the weather

>>1308552
>If you are going to work satellites VHF UHF may be ok in the middle of nowhere
I figure that would work, but I'm more of wondering how many other people who may be inside radio line of sight would happen to have radios operating on the amateur bands with them. I'd just go with HF if I wanted something that would require stopping to set up my radio.

>>1309044
Depends on where. Australia here. 100 watt hf mobile is common in outback areas on non ham bands. We also have UHF cb which is commonly used for line of site comms on outback stations many of which have their own repeater. That is good for about 30km mobile mobile on flat ground or more with a repeater. It's a matter of knowing the area and what is used. Where are you asking for?

>>1309068
>100 watt hf mobile is common in outback areas on non ham bands
Is that legal without any kind of license in Australia?

>Where are you asking for?
The US.

>>1309114
>legal without any kind of license
I very much doubt that. Australia certainly has its own ham licence which is required for anything other than using a wifi router or FM audio sender.

>>1309114
>Is that legal without any kind of license in Australia?

No. They have licenses other than ham for such things. No reason you can't use ham in the outback but there are a lot of people using other frequencies.

http://www.beadelltours.com.au/hf_information.html

HF has been about for a long time in the outback and now our manufactures export the stuff.

>>1309147
Jesus, it's been years since I've seen that bad of an eye cancer inducing website. I never thought I'd feel nostalgic over such a thing.

It is a bit of a blast from the passed.

They used to even teach school on HF but now satellite internet has taken over that mostly.

https://www.assoa.nt.edu.au/

Are there any man portable rugged HF options that don't weigh as much as a base station and take up an entire backpack like all the older military ones I'm seeing do, and also supports CW (as the rugged business options don't seem to)?

>>1309172
Some hams build FT817s into cases for this.

Any Canadian-hams?
I want to go about getting my license but the Industry Canada website is a little confusing. Do I need to locate a club to get started or can I start online?

>>1306608
Motorola makes some indestructible state of the art gear but:
Radios are no longer supported once the new version comes out.
Requires proprietary software and cables to program. If programmed with the latest software you will not be able to use the older versions to access the radio.
May require a radio interface box ($$) to program.
May need a slow computer running DOS to program.
Narrow bandwidth may not do ham stuff.
No front panel programming, so you can drag your computer, rib box and cables with you while traveling.
Any mishap while writing to the radio = brick.

>>1309326
I was aware of these problems but would like to point a few things out.

>May require a radio interface box ($$) to program.
The schematics for those are public and people can and do build them themselves. I realized that later and it does bring down the price of the Motorola radio vs new stuff from Kenwood/Icom/Yaesu.

>Narrow bandwidth may not do ham stuff.
Motorola's narrow band capable radios can still be set to wideband on a per channel basis. Also, some newer amateur radio gear can do narrowband transmit as well, and while I can't remember how receiving wideband FM with a radio in narrowband mode turns out one can receive narrowband FM with a receiver in wideband mode (it's just quieter).

>No front panel programming, so you can drag your computer, rib box and cables with you while traveling.
That didn't bother me too much, considering there were options with enough memory spots for all the repeaters I might want to use.

>>1306608
Ended up deciding against it, not because of any problems with Motorola radios but because the 2 meter band is pretty dead locally and almost all activity (other than digital mode stuff) is on a single 70cm repeater while it seems that if I was to want to use a radio outside my city I would need something on the 2 meter band due to the lack of other non digital mode 70cm repeaters throughout most of my state and the lack of repeaters coverage in general in some areas. I still really want to get a Motorola radio to mess around with, but can't justify it if I either end up with something I can't use unless I'm traveling or end up being locked into local infrastructure that completely defeats the purpose of a radio IMO.

>listening to HF on a scanner

Is a antenna's physical length more important than it's material length? Like, take this Bluetooth antenna trace, would I measure it end-to-end or would I measure along the path it follows?

And say I have a randomwire antenna but I want to shorten it without cutting it, can I just fold the end back and tape the folded part flush to the rest of the antenna?

>>1311526
uhh no. its a folded antenna. it's not a dipole. the squiggles are waveguides. there's no way for a peasant like you to measure it. other than just knowing it's meant for bluetooth .

>>1311526
Material length (measure the path). That's how coils can make antennas smaller physically but electrically resonant. Folding the antenna back to shorten it will work if the wire is uninsulated and touching itself.

Just for S&G, a half-wave antenna, smack-dab in the middle of the bluetooth frequencies, (2441Mhz) would be 2.30 inches (5.842cm) long.

>>1311549

Q-codes are more reliable and more efficient (less time is needed to convey the info).

Why are you using speech then?

>>1313483
do you use acronyms like WTF, STFU, GTFO, OMG etc, e.g., i.e.? Or something from sms speak like g8, cu? I bet you either use them or know what that stuff menaing. Using these acronyms is reasonable as it's more efficient (less time to type or write, the sentence takes less space).

Do you know what ten-codes are and why are they used instead of plain speech? It's all about the media (radio).

>>1298288

Alright DIY nigs,
I'm looking to build a helical for INMARSAT reception ~1.5GHz. I've got an antenna calculator and a book on antennas, for the specs but I need a form to wrap the coil around.

Any ideas?

The form needs to be around 2.5" in diameter, rigid, non-conductive, and allow for fabricating a matching network between the coil and the ground plane. Should keep the correct coil spacing aswell.

I would like something easy instead of making a rigid pole and drilling a bunch of shit and adding support element like in pic related.

>>1313891
PVC pipe? Cardboard tube for initial fabrication? You can wind it around something like a cardboard clingfilm roll and then mount it via holes in a couple of bits of rigid plywood or plastic. Like pic related.

>>1313896
There aren't really any cardboard tubes readily available in that diameter.

The problem with something like PVC is that in order to do a simple transmission line-like matching network you need to cut out a chunk of the PVC near the bottom but have it support the rest of the coil.

I was thinking about using some kind of foam maybe because it could be easily cut to the right shape. I don't know shit about foam though.

>>1313911
Again, you don't need to use the tubing to support the coil, just use a plastic ruler or PCB or something for that. A bit of timber should work great for that diameter, and easy to carve grooves into for the helix itself.

>>1313876
>You don't use q-codes for normal phone transmissions. You might hear qrz but that's about it.

Has anyone else ever messed around with extremely low power CW on the VHF or UHF bands? Considering CW can be copied by ear at 1/20th the signal strength vs SSB voice which in turn can be copied at 1/10th the signal strength of FM voice, one could get some serious performance on low power when compared to the radios people normally use on the VHF and UHF bands. With most mobile rigs running FM at 25-50 watts, you would only need to run CW at 125-250 mW to get similar performance. Part of me thinks it would be really cool to attempt to integrate a really low power transceiver into a key just barely larger than the Palm Radio mini keys. I've seen QRPp transceivers that can put off 100-200 mW when powered by a AA battery, so a 3 V coin cell or small battery pack should be usable for such a task. I'm not sure if having a person touching the ground plain on an antenna would be a problem, but if not such a radio could transmit on the 70cm band and have a small integrated telescoping 1/4 wave antenna, have a magnet base to keep the radio from moving while being used, and use whatever metal object it's attached to as a ground plain.

What kind of receive filter do Baofeng radios have?
>inb4 none
I'm wondering because I decided to test the selectivity myself by opening the squelch and transmitting with an old FRS (not GMRS) radio from the early 2000s in the same room. With the old FRS radio set on channel 1 (462.5625 MHz) I could still hear the roger beep with my Baofeng BF-F8+ tuned to channel 4 (462.6375 MHz), and could still hear some distortion with it tuned to channel 5 (462.6625 MHz).

On a side note, I actually heard some kid trying to respond to my repeated roger beeps asking if anyone was there. Too bad FM sucks to listen to with open squelch unlike other modes, as that made me realize I could probably hear a lot more (especially because it would allow me to listen to some 150 KHz of bandwidth at a time assuming the signal is strong enough).

>>1317366
Shit tier, check if your Baotrash is in NFM mode.

>>1317381
It was in NFM mode, but IIRC that just changes the transmit bandwidth.

>>1317383
>that just changes the transmit bandwidth
No. You were probably overloading the front end of the Bao if you were using the FRS radio next to it. Don't expect performance from a $35 radio. A similar model from Yaesu, Icom, or Kenwood would set you back $150 - $200

>>1317351
No, but you could microwave yourself to death if you went to close to them while they are transmitting. I don't mean "water molecule resonance" microwave, but just general RF burn.

>>1317403
>You were probably overloading the front end
Doesn't that normally result in deafening the radio? I could still receive when tuned to the same channel as the FRS radio on the Baofeng without the squelch open.

>>1315016
>I'm a ham, don't preach your bullshit to me.
You've clearly spent little to no time on HF bands. People do use Q-code as well as phonetic alphabet on air.

>>1316849
>Well if you have more than one. Antennae is the correct plural form of antenna.

You must have more than one if you are a genuine radio-amateur. I haven't seen one with only one antenna, most have few rigs and few have few full-sized shit with rotators. Most guys I hear on HF are having full-sized yagis for 20-40-80 meters.

>>1298167
Well spoken, oldfag

>>1317563
>get a downconverter and find a numbers station
1st, it's not a downconverter it's upconverter.

2nd, upconverters for RTL-SDR are pure shit due to very limited dynamic range of the RTL-SDR. It's ADC is 8 bit and it can do like 2.5-3.2 msps. Receiver bandwith is about 2 megahertz.

Thus you will always get few high-power radio SW radio stations (100-500 kW), you won't be able to list to a signal that's being broadcasted with much less than that.

Get a decent SDR you want to listen HF/SW. RTL-SDR + upconverter = listening to a SW broadcasting stations only.

>>1317563
>>1317641
Can't an RTL-SDR be used in direct sample mode to get onto the HF bands without an upconverter?

>>1317659
Yes. On older versions you have to do a hardware modification but newer versions support it out of the box.

>>1308536
>Is that ham?

Close! Long pork.

I used to listen to shortwave radio a bit and was wondering if you all could explain the principals of how this setup works. IIRC it's from a old Voice of America/Radio Free Europe/Radio Free Asia pamphlet that was clandestinely distributed in communist countries in the 80s, and is intended to mitigate signal jamming or interference. You were supposed to connect the first antenna to the pad of tinfoil the radio sits on and then the second empty pad of tinfoil would be connected to the radio's antenna.

>>1317294
First off the Wullenweber is mainly used for DF which is reception. It can also be used for directed transmission. In any case a good antenna means you do not have to emit power levels that will put the air on fire.

>>1317351
Quite unlikely.

>>1317408
Check the size of the elements. Those are for HF frequencies, not microwaves. For microwave DF the constructions are rather different.


>>1317563
>it was a Cold War direction finding antenna complex
Yes, except that they are reviving that design, possibly making even vaster designs.

How does RTL-SDR compare to a Baofeng for receiving? My Baofeng really doesn't work too well as a scanner since it can only scan 3 channels per second and I'd like to be able to use longer scan lists without making it extremely likely to miss activity due to the large amount of dead channels I'd be covering. Also, can software for RTL-SDR like GQRX handle multiple squelch settings depending on what frequency you're on as a way to deal with increased noise on certain frequencies rather than just skipping those frequencies or setting the squelch higher overall and missing weaker signals on other frequencies?

>>1317767
>Those are for HF frequencies, not microwaves.
I was more going for the general explanation of an RF burn as opposed to specifying a radio band.

>>1317417
>People do use Q-code as well as phonetic alphabet on air.
Sure, the same people use as many 10-codes as possible when using FM too.

>>1317823
a lot better, as you can demodulate many channels simultaneously limited only by CPU and the RTL's 2MHz receive bandwidth. can't speak to front end sensitivity though
>gqrx
remembers squelch settings in its bookmarks, but only demodulates one station at a time. you would probably have to assemble a multi-rx with GNU Radio, if nobody's made a scanner app

Direct-conversion without band-pass filters and with 8-bit ADC provides really marginal performance.

>>1317913
>>People do use Q-code as well as phonetic alphabet on air.
>Sure, the same people use as many 10-codes as possible when using FM too.
Phonetic alphabet is used extremely often in HF ham communications. Q-codes are used on HW in SSB as well. More so in CW.

Ten-codes are used by military/policemens/security, but I haven't heard of any ham using ten-codes even on VHF/UFH. I'm not sure if it's even legal as ham communication is limited and you for example can't broadcast music.

>>1317929
Hams generally don't use ten codes because they vary widely between regions. Like a code used in LA for "I need backup" could mean "I'm stopping to take a shit" in NYC, and a lot of the codes are also specifically police/fire related stuff like "I need to talk to a supervisor" or "I need a license plate check on XX."

That's the point, geniuses, idiots that use q-codes during normal phone contacts are the same that use 10-codes or phonetics on 2m FM. Unless you are contesting, using CW, or trying to make a contact under terrible conditions you don't use q-codes. Read an operating manual, figure out how to not be a lid.

Also, if you are questioning the legality of 10-codes on ham radio, you have no business being in this conversation.

>>1317952
>That's the point, geniuses, idiots that use q-codes during normal phone contacts are the same that use 10-codes or phonetics on 2m FM
Let's faced it, we have two options:
- majority of hams (worldwide!) on HF bands are idiots since they use Q-code and phonetic alphabet.
- the idiot is you and majority of hams on HF bands (and sometimes on VHF/UHF while doing EME/ERE or stuff like that) are sane persons who use international code to make conversation easier, faster and more reliable.

>>1317952
>Also, if you are questioning the legality of 10-codes on ham radio, you have no business being in this conversation.


FCC part 97 forbids encrypted communication for amateur use. No amateur radio transmission can be encoded or encrypted in any way that is intended to obfuscate or hide the content of the transmission.

Thus I guess using non-standard codes is prohibited. 99% you can get away as no one is enforcing that. But anyway strctly speaking it's not 100% legal.

BTW the only man here who has no business being in this conversiation due to lack of knowledge, experience and ignorance is you. :D

I just want to get a radio for local weather alerts, EMS scanning, and police scanning. Seems like it'd be handy, honestly. Not sure where to take the test, though.

P.S. can you choose a callsign that isn't phonetic? Kind of like CB, I guess.

>>1317938
>taking the bait

nah but lots of people get a vanity callsign that consists of a couple of mandatory region-specific prefix characters plus their initials.

>>1318012

Well, I'm sure that if I start listening I'll also want to start speaking too. Or at least have the option. I'm a bit disappointed by the inability to choose my callsign though.

>>1317993
>Unless you are contesting, using CW, or trying to make a contact under terrible conditions you don't use q-codes.
Do you not understand this? Are you so dense you cannot comprehend using a radio without q-codes? Spewing shit out of part 97 of the FCC regulations, then saying "I guess . . ." means you are talking out your ass. I've had my ticket for 8 years. I primarily work HF, specifically 80m, 40m, 30m, 20m, 15m. I stay away from VHF and UHF because of idiots, like you, with their baofengs know all and try to BS anything and everything.
>Let's kerchunk the repeater 10 times, then ID using the phonetic alphabet after stepping on someone else keying up.
So in conclusion, fuck you I'm done arguing with your faggot boi ass. xDDDDD

>>1318066
>Do you not understand this? Are you so dense you cannot comprehend using a radio without q-codes?
Why are you so angry? You have troubles remembering a dozen of most popular Q-codes?

You are clearly talk about shit you know nothing about. I'm just referring to a common practice and stuff I hear on HF bands. Ragchewing with local guys doesn't count.

Get a decent antenna and a rig to enjoy DX'ing. Working on VHF is boring, unless you into EME/ERE stuff (but you aren't smart enough to do that I see).

If you aren't talking off your ass post pics of antennas and your TRX.

>>1318066

Having your "ticket" for 8 years doesn't mean you aren't ignorant prick, who thinks that hams are idiots worldwide for using Q-Codes and phonetic alphabet on HF/SSB and VHF.

Using non-standard / self-coined codes is illegal as it's clearly obfuscates radio communications.

Here is an excerpt from www.arrl.org with comments:


2. Article 25 of the international Radio Regulations (RR25.2A) includes the following
provision, which constitutes a treaty obligation of administrations: “Transmissions between
amateur stations of different countries shall not be encoded for the purpose of obscuring their
meaning, except for control signals exchanged between earth command stations and space
stations in the amateur-satellite service.” 3 This treaty obligation applies only to international
Amateur Radio communications. Domestically, however, Section 97.113(a)(4) of the
Commission’s Rules in its present iteration uses similar phraseology. Prohibited transmissions in
the Amateur Radio Service include those “messages encoded for the purpose of obscuring their
meaning, except as otherwise provided herein.” 47 C.F.R. § 97.113(a)(4). Until 2006, FCC rules
prohibited the transmissions of messages in codes or ciphers which are intended to obscure the
meaning thereof, except as otherwise provided in the FCC Part 97 Rules. That rule also
prohibited the use of “false or deceptive messages, signals, or identification.” The rule section
was revised by Order, DA 06-79, 21 FCC Rcd. 278, released January 19, 2006. 4 That Order
amended numerous rule sections in Part 97 to conform to the current language of the
International Radio Regulations, which were amended substantially at the 2003 World
Radiocommunication Conference (WRC-03).

Not the same guy but I find this funny. I just got my general ticket yesterday (tech/general at once), and I'm trying to decide on a radio. Having heard the local chatter, I think I'm going to skip 2meter/70cm entirely and go to HF. Everyone is either agro, or mansplainin.

>>1318085

>>1318085
>, I think I'm going to skip 2meter/70cm/23cm entirely
You can communicate with ISS, receive weather maps from satellites. If you get a decent PA & antenna you can try EME or ERE. Other than that I too find these bands boring.


BTW why do US-fags measure wavelength in meters and centimeters?

I really need to learn Morse code and get into HF. I hope it isn't this dead everywhere.

>Many new Radio Amateurs start with telephony (Phone) yet use the Q-code which is meant for Morse Code (CW) use, and not for Phone. On phone there is little point in saying “there is some QRM on your signal” instead of simply saying “there is some interference on your signal”. Many new Licensees seem to think that they should use the Q-Code simply because they are Radio Amateurs. However, there is a case for using Q-Codes on telephony if the operators do not share a common language. When they both converse in the same language, there is little point in using signals designed and intended for Morse Code (CW) use.

I had the opportunity to change to the whip antenna during a long conversation I was listening to on a local repeater when the signal was getting really shitty and suddenly the signal got clear again.

That one, like the Elecraft ones, is provided with a floating point DSP. These are fast for software development but have a lot of disadvantages compared to fixed point DSP:
- more expensive
- slower
- uses more power (and TI was never one to go for power efficiency)
- uses more silicon area, thus reducing efficiency and possibility of denser integration and more on chip RAM
- more complex and thus more likely to be buggy

Snapdragon, on the other hand, has Hexagon DSP units that are fast fixed point units.

Alright then. On a side note:
>60-20 just kind of goes to shit in the Winter
So if I need a portable HF rig (and therefore need to run at around QRP power levels if I don't want batteries to be an issue), I'm going to want to be able to use it on the 80 meter band if I want to make any contacts during the winter? I'm considering getting into HF, but I'm kind of limited with my apartment being a basement level apartment on the back side of a building with no room to set up an antenna directly outside my apartment and with no roof access (and a power line going to the top of the roof directly above my apartment so even if I could climb up there I'm not sure it would be safe), so I think I'm pretty much going to need something portable unless I want to attempt NVIS at below ground level.

>>1320745
Tough call because antennas are a very touchy issue. I could find 10 guys who will love a G5RV (myself included) and 100 who hate them.

I'll say 40 Meters is "shit" compared to Summer RX/TX but still quite good. 20 is nice in the day, not great but I can chat sky wave with it right now.

If you're limited in space; I'd say go with a Magnetic Loop for 80 through 20. Just getting it a few feet off the ground will do wonders. Its downfall is that you need to tune the air capacitor and check SWR every time you switch a frequency. Bit of a PITA.

MFJ offers a "balcony" antenna that you could mount to a broom stick outside a window that works fairly well, might need quite a few grounds though.

If you're allowed to, try running a long wire like a 40 foot or 63 foot Emcomm up a tree and over to the corner of the yard's fence to a 9:1 Unun and trail a counterpoise an inch or two under the grass.

NVIS inside a building going to be awful.

I don't think you understand how bad it is. There are no trees, and there's a sidewalk that butts up against the building around where my apartment is located that gets used every so often so I can't put up anything that would block it. I'll look a bit more into the magnetic loop antenna, but that sounds like a pain in the ass and I'd still need to find a way to get it a bit more than a few feet off the ground to prevent the neighbor's kids from trying to mess with it.

>>1320826
Try the small transmitting loop. I have beat 5000 miles per watt from my living room in a valley with a 30cm diameter loop. You can null out qrn and qrm by rotation. I often use 2 sizes of pexal to make a 2 turn loop with sleeve capacitor. Use nylon bolt to tune by spreading the turns. Very high q. 5 dollar monoband.

Anyone got that handy buy guide?

>>1320983
Really depends on what you're looking for. Dual Band mobile? HT? HF Rig? Receiver only?

Anything you think you want to buy, I'd suggest reading the reviews over at Eham.net before buying. A good rule of thumb is you can't go wrong with the "Big Three" (ICOM, Yeasu, Kenwood) but with quality comes expense (My TS-590SG is a middle of the road Kenwood and still $1500). Each brand has their distinct bells and whistles and cons. Kenwood's internal antenna tuners are top notch as are their pre amps, ICOMs have proprietary accessories that really make them sing (IC-7300 is very popular) and whatnot.

>>1320871
Why do they even used switched-mode power supplies for those? Surely it would be better to use the right number of LEDs in series + a capacitor and full-bridge + a linear constant-current regulator to take the remaining sub-5V out of the supply to keep the LEDs from frying themselves. If you have a stable enough peak mains voltage then the losses through the linear regulators would probably be lower than those from a switching transistor.

>>1320999
How about Elecraft? I thought those were pretty good.

>>1321170
Elecraft and TenTec are fantastic. I meant the rule of thumb for beginner or general hobbyist. When you're looking at Elecraft or TenTec, you're looking at $5000+ in gear.

>>1320983
>buy
>diy

>>1321197
Eh, you rarely diy a transceiver unless it's something like a QRP (low power) mcHF. Much of the diy is your baluns, unus, antennas (antenna builds are fun and sometimes challenging) and experimenting with variations of the like.

People do DIY power amplifiers as that requires less knowledge and easier to do.

Building a transceiver is harder, but nowadays building a decent SDR or DDC/DUC is easy and you'll get decent performance for cheap.

>>1321219
I want to build a 5-6 tube/valve 600 watt amp but I can't find any air caps or a good transformer for a reasonable price.

>>1321206
A few I know of DIY transmitters. They are mostly the am guys. One guy can even do cquam on 160.

>>1321222
5-6 Tube amp for 600 watt is over complicated.

You better get something like a pair of GK71, a pair of GU13, or a one GU81/GU80, it's cheaper and less prone to oscillation. You can also get 2x Gi7B or one GS35.

For HV it's hard to advise anything, if you have 240V you may want to look at transformer-less PA construction (HV multiplier), it's cheaper to build PA but it's way more complex due to grounding issues.

High voltage caps can be easily DIY'ed.

MOT can be pressed into service in some cases. A few may be required.

I discovered why I have an S7 floor on lower bands. Not only do I have a 7-Eleven with LEDs behind me, but there's a 5,000 Watt AM radio station transmitter 1/2 of a mile from me, with the power lines between us running perfectly parallel to my house.

Anyone know a good band pass filter?

Surely that's some kind of offence that could get them raided by the radio nazis. But see if you can cover the PSUs with better shielding. If its fundamental is below 20kHz, listen about it with an amplified inductor plugged int your headphones running off a 9V battery to search for the leaks. A pocket scope will also work.

>>1322577
>>1322596
Sent a screenshot of the offending signal to the FCC this morning as my SDR picks it up. Every line in this waterfall is their station.

I also tuned around the bands on my two HF rigs (IC-7300 and FT990) and documented the frequencies I picked them up on.

I seriously thought I was just picking up a lot of foreign South American stations all this time. Nope, just one local Mexican radio station.

>>1322710
What SDR are you using?

>>1322268
>I found a TS-590SG for $200
Fuck that's nice! Are there any more units left? I'd love one for $200 :D

>>1322723
That was my RSP1 hooked to a random wire. I also hooked an RTL-SDR V.3 I bought to make a pseudodoppler for foxhunting up and pretty much got the same signals.

>>1322724
Retired Homeland Security Director (State Level) had the TS-590SG as one of his back up units and he new me from my days as a medic. He was happy I finally got into ham and when I told him I was miles away from an HF rig since I'm now a poor fag, he asked how much I had saved up. He said, "Tell you what, I'll sell you a TS-590SG for $200 with a free power supply. Use the rest of your money for an antenna and everything else."

Couldn't beat the deal and couldn't be happier with the radio. The internal tuner tunes up every band a G5RV was made for. Only need an external for 60 meters and 30 meters.

I hooked an Avantone Mix Cube up as an external speaker and it has incredible sound.

>>1322967
Old-school ham.

>>1322997
Awesome guy. We're out of range for ground wave and too short for sky wave and he doesn't do VHF or UHF so we get together for beers at least every month. He didn't even tell me he was giving me an MC-90 mic with it.

Bad LED design is a menace that will be with us for a long time. Early designs were really bad but I am not sure more recent designs are really that much better. Add to this that these can last 20 years and are absolutely everywhere from toys to street lighting the EM fog will most likely grow for at least 10 years before levelling out. Given the enormous life time it will be another 10 years before we see meaningful decrease in radio noise.

Since noise does not correlate I guess even HF hams will have to use beam forming antennas to get through this mess.

>>1322596
>Surely that's some kind of offence that could get them raided by the radio nazis.

Probably a Christian station. The FCC won't touch them or every hillbilly in the area will be up in arms.

>>1322710
That sucks my nearby church is on FM but blacks out every band for about a mile am and FM. instead of a peak it's a blob on my spectrum analyzer. Good luck the FCC doesn't care they gave them the licence for a low power station. as long as it's not interfering with local or federal government or somewhere they make money like cell phone the will do nothing. Oh if you get 5 or more complaints they might make a list for a letter so get your neighborhood to send in complaints too.

>>1323267
beaners? you think they'll care?

>>1320074
That picture is making me wonder exactly how much rag chew occurs on HF using the various modes. I really haven't listened much on HF as I don't know morse code, definitely can't afford anything capable of doing voice over a decent amount of distance which kills my interest in that, and I don't think the online SDRs are capable of decoding the digital modes. About how much activity on HF is just doing the bare minimum call sign/location/signal report exchange beyond the obvious with ~56% of the activity being FT8?

>>1298149
Make a horn antenna from the magnitron in your microwave.

Turn it on and off to blast your call sign in morse code. Your allowed to tx 1.4kw if I remember correctly.

If someone bitches about "minimum power to desired communication" or whatever tell them your trying to communicate with the ghosts of the dammed and it takes that much power to get through.

>>1323182
I bet tesla chargers and EV chargers in general will make HF communication impossible in few years.

Most chargers lack proper EMI shielding and all of them are really high power devices, switching tens/hundreds of amps at hundreds of khz.

>>1323435
I have a CW decoder on my TS-590SG. I don't know CW well enough to keep up on my own, so I read the decoder. Those guys LOVE to rag chew.

You really only need a cheaper HF set with 100 watts output to get going. An Icom IC-718 or Yaesu FT-450D will set you back $700 or so new and both have 100 watts and are AWESOME entry level radios. An Alinco DX-SR8T isn't bad for $500 new.

If you're willing to settle for used equipment, you can find those rigs or at least their generation older versions for $200 to $400 at your local ham fest (there's been 3 already this year in my city). Buy a True Tune G5RV antenna for $100 on Ebay if you have a small yard and a tall tree (the feed point has to be 32 feet or higher and if you can do that, this is a fucking awesome antenna).

>>1323435
Oh, and the market is about to be flooded with used IC-7300s you should be able to get for $600 or so.

>>1323539
>Oh, and the market is about to be flooded with used IC-7300s you should be able to get for $600 or so.

>>1323514
pretty sure power supply hash is not a primary spectrum user. anything that drives that grifting huckster bankrupt is fine by me
are you implying that the future of DX is birbs?

yep low frequency & low HF bands will be dead soon. Give or take 10-20 years.

I'm not that old but I remember that LF/HF bands were much quieter esp in urban areas (that's like 20 years ago).

With advance of LED lighting, EV's and EV's chargers we will have thousands and millions of SMPS's connected to the grid and that shit will radiate using power lines as massive antennas across the globe. You'll have to pump like few kilowatts to overcome man made noise.

>>1323643
don't forget about half a dozen switchers in every pocket
in every PC or laptop
in every TV
in every router
one in every charger
it's like a Kessler Syndrome but with non-ionizing radiation

>>1323643
Who knows, we may get lucky and end up with there being so much spurious emissions that it actually improves propagation conditions in the ionosphere so that higher frequency bands are always open to counter the other predictions of the higher HF bands ceasing to be usable in the near future due to prolonged low sunspot activity.

>>1323783
Low-power devices aren't that bad, they generally come with adequate EMI/EMC filters.

Still you will likely be unable to receive anything on HF now if you are using antenna indoor near your appliances. Laptop/TV screens are radiating at HF and VHF while SMPS flood MW

High power SMPS are switching hundred(s) of amps and not 0.5-5A. They generate a lot of EMI noise.

Is there any inexpensive way to find out if you'll have any high noise floor/interference issues due to your surroundings before dropping money on an HF rig? I know people use various handheld radios to find interference but that doesn't exactly tell you how much there is. Would an RTL-SDR be good enough?

>>1324140
A regular AM radio.

>>1324152
>I know people use various handheld radios to find interference but that doesn't exactly tell you how much there is

>>1324153
If you are are contemplating a HF radio because of the possibility of noise, don't bother. You're obviously too lazy to learn about how to deal with common issues.

>>1324157
I understand finding noise around my apartment and fixing it, as I've already dealt with some noise issues on the 2 meter band. However, an AM radio won't tell me exactly how much noise I'm going to have to deal with from sources that I can't fix.

>>1324152
I'd actually make a receiver instead so you can avoid the automatic gain control, allowing you to scan across the frequencies for direct noise, instead of having to set a frequency and tell how bad the interference is from the surrounding noise.

>>1324157
why don't you stop being a prick or acting like an "Elmer", and use your fucking words to help novices. 73, you cunt.

>>1324140
>Would an RTL-SDR be good enough?
Unlikely since it does not perform well below 22 MHz. You really want a receiver that covers the entire HF band.

>>1313891
How about the inside of a roll of carpet? I picked up a few thick cardboard rolls or of a skip near a carpet shop. They would have to be about 2.5 inches in diameter and strong as fuck.

>>1324140
1. You will have lots of noise on HF bands
2. You need outdoor antenna for HF.
3. You may try to get a way with magnetic loop antenna for SWL-ing. It is way-way better in noisy environment as it doesn't pick up E-field and thus doesn't pick up lots of near-field noise.

anyone have any success making contacts with an SDR transceiver and a PA?

for that survey task, you would probably want to consider an SDR device designed for lower-frequency work

Last I checked they don't make HF rigs. There are some really cheap HF rigs coming out now days though like the uBITX which can do CW/SSB at 10 watts on every HF band for $130 (but it doesn't come with a case).

>>1324492
>one would take it up and work around the faults, not be a wishy washy tire kicker when it comes to acquiring equipment.
Say no more. I'm dropping money on an Icom IC-402 to do CW DX on the 70cm band. Hopefully I can work around the fault of no one doing CW on the 70cm band unless it involves cross band operation and a satellite, which the single band IC-402 isn't suitable for.

Woke up early again today and still no local amateur radio club net. On further looking, they don't even seem to have it on their online calendar like they do the weekly ARES/RACES combined net or their 2 meter SSB net. The lack of VHF/UHF activity in the area is really discouraging for someone who really wants to play around with easily portable equipment and keeps getting told HF QRP is too difficult for beginners among other things.

>>1325674
what kind of antenna are you using? i built a copper jpole and it doubled or tripled my range. have you looked at radio reference? that should show you all the repeaters in your area. if you can find a local club i would definitely join that or at least attend a few meetings. the old people on the air can be a bunch of cunt, especially to younger users. be nice, but dont take their shit. the frequencies are for anyone to use.
why do you want to use QRP? do you hike, or camp a lot? i would recommend starting with an hf rig first, and moving on to QRP

>>1325732
>what kind of antenna are you using?
Currently a Nagoya NA-701 because my router/PC power supply/other shit overload my shitty Baofeng on some frequencies when I use the wire antenna I made. I've already checked multiple listings and narrowed down the inaccurate/out of date ones (which are actually surprisingly common) and can hear all the repeaters in my area, including two that are 33 miles away (one on the 2 meter band and one on the 70 cm band). I have been considering putting an antenna higher up outside to see if I can't pick up more on the 2 meter simplex frequencies or maybe something else interesting like SSTV as I live in a bad spot but have run into issues with how to mount it in a non permanent way so as to not cause problems with my landlord.

>why do you want to use QRP? do you hike, or camp a lot?
It's a combination of factors. But the main contributors are the costs involved with setting everything up when I've been using the internet since the late 90s. It's a lot harder for me to justify purchasing expensive gear to do less than what I've come to accept as part of every day life over the past 2 decades. Using low power gear that can be run on batteries to reach out long distances while away from home still interests me though (even with the limitations of needing to set up an antenna), along with the idea of possibly building something myself (which from my reading is pretty much limited to QRP power levels if you want to build a transceiver). I also don't need more reasons to stay at home.

>i would recommend starting with an hf rig first
That's what I figure I'll do when I get more money. Until then I was hoping to get some enjoyment out of VHF/UHF equipment. I'm hoping I can pick up more with a decent antenna and that would likely motivate me to upgrade from my shitty Baofeng and get more involved. If that doesn't work though and I can't blame it on receiver overload I'll likely just fall back on CB radio since at least that's active.

>>1325732
>>1325771
On a side note, I finally got my APRS software working, so that should keep me entertained for a little while. I hope it isn't just used for location data in my area.

>>1325771
An external antenna will make a huge difference. An extremely easy solution for an external antenna is to use a mag mount. Stick it on a car, a metal table, whatever. A simple ground plane antenna will work great. It can be made out of some solid wire (house 14 - 10 gauge) and a chassis mount connector.

,>>1325509
Ditto. What do you think so far? I just got my ticket and it's my first rig.

>>1325821
I was thinking about a magnet mount since there's a covered area with a metal roof on the apartment building I live in that is right outside my window and I really haven't been able to think of another way to mount an antenna without drilling into the side of the building or something. There are supports for the covered area that I could possibly attach an antenna to as well, but I'd need to make a rather large spacer to put between the support and the mast to get the mast outside of the covered area.

>>1325771
an external antenna will help a lot. even if you just make a slim jim or a ground place like >>1325821 . that was the first one i ever made, but mine was for 2 meters, and that worked on 70cm as well.
ive seen people built qrp kits and other basic transceivers. its something that im interested in, but thats down the road for me. ill be happy with the 100 watts i have for now for awhile. besides radios and feedline, you can build all your antennas and baluns. you can actually even make your own ladder line if you want to.
im sure you can find enjoyment with just vhf/uhf i love scanning around the police and fire bands, to the point im running 5 scanners, an ft-8900, and my new IC-7300. i would suggest buying a cheep used scanner off ebay, it will scan a lot faster than your baokajigger. also an easy way to find what channels around you are worth listening to.
>>1325783
nice, thats something also id like to get into, and upload my weather data to. what software are you using?
>>1325821
that was the first antenna i built, but for 2meters. my god, was it ugly, was learning how to solder still. it worked great. built a jpole after that and i can now hit repeaters really far away. when summer come i have a yagi i built ready to go up. building them and seeing them work is so much fun.
>>1325851
i love it. i feel like its a real steal for the price. so much is packed into that little radio. used it on field day and i had to most contacts by far, and im pretty sure that was just because of how easy it was to find with the waterfall. id like to hook it up to a tv, just for a nice big display
>>1325860
can you get on the roof? is it flat? mag mounts work pretty good, i use one when im out tinkering in the garage. i plan on building a slimjim and putting that in PVC pipe so i can mount it a lot higher. i might swing it over a tree branch to get some more hight

>>1325874
>i would suggest buying a cheep used scanner off ebay, it will scan a lot faster than your baokajigger.
I've actually considered buying an RTL-SDR for scanning. My Baofeng definitely isn't suited for it with its 3 channel per second scan rate.

>nice, thats something also id like to get into, and upload my weather data to. what software are you using?
Direwolf on Linux.

>can you get on the roof?
Of the actual apartment building? Not without a large ladder. I can however reach on top of the metal overhang with a small stool

>and putting that in PVC pipe so i can mount it a lot higher
I thought I read somewhere that PVC pipe really doesn't like sunlight.

>>1325881
i havent seen any scanning programs for scanning with RTL-SDRs, at least not on linux. ill have to get direwolf again and try that out for APRS.
the pvc will definitely last a few years, and by then youll probably a better antenna.

Shit, Direwolf stopped decoding packets and isn't working again. The problem seems to be either the cable/2.5mm to 3.5mm adapter, distortion, or the signal not being loud enough for Direwolf to decode (probably the least likely). This shit is annoying as hell to troubleshoot given the small amount of APRS activity I'm picking up.

Jesus fucking christ. At least I found out why it seemed like there was so little APRS traffic vs when I listened without my radio hooked up to my computer. I'm going to guess this is why Direwolf stopped decoding APRS packets as well.

Here's a question for RF antennanons.

Let's say I want to run a 2.4 Ghz point-to-point link between my house and a friend's. However, some jerk who lives nearby (but NOT on the LoS path between our transceivers) keeps sending malicious packets to one or both receivers which interrupt our connection.

How can I narrow the Rx sensitivity of the transceivers such that they only "see" along the LoS path between them, and reject all outside noise?

For the sake of argument, let's assume that jerk broadcasts with high gain and more than enough power. Would a cylindrical copper shroud of sufficient, yet reasonable (<1m) length around both receivers isolate them sufficiently?

Essentially, I'm looking to replicate the receive characteristics of a laser datalink. I'm less concerned about send characteristics - my data's all encrypted, since we're on the ISM band. I'm open to all sorts of antenna configurations and enclosures, but I'd prefer to stick with RF instead of laser links for reliability.

Just to elaborate, I'm not worried about amplified frequency jamming (in which case I'd call the FCC), only ping-of-death style intelligent connection resets.

Shouldn't this be a software solution?
