I needed a new heel for my shoe, so, I decided to go to Morganville, which is what they called Shelbyville in those days. So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days, nickels had pictures of bumblebees on 'em. "Give me five bees for a quarter," you'd say.

Now where were we? Oh yeah: the important thing was I had an onion on my belt, which was the style at the time. They didn't have white onions because of the war. The only thing you could get was those big yellow ones.

Yes, it's a bit of a joke, I've measured its consumption to 26 W with the power amplifier module disconnected, most of it being lost in the now extremely oversized power transformer. I really have no clue what the actual radiated power is, coming out of my 70 cm piece of copper wire, but I wouldn't imagine I've made a particularly good antenna for it.

I'm from France, we only have one license here. I'm guessing you're asking for the max power, we can do 500W under 28MHz and 250W on the 10m band.
Not so sure about budget, I guess a good rig is a long term investment so I'd try not to cheap out too much.

>Satellite FM
That's really going to be your cheapest and quickest entry point. I haven't actually done it, but seems really exciting and you can make your own antenna from actual trash. I think you'd need to pick up another Baofeng if memory serves right. I've seen a few good youtube videos on the subject, but haven't had time to explore it

>HF
That's what I started with last year and haven't turned back. It's not cheap. I'm the Digital FT-101 anon if anyone remembers that far back. I owe this thread a ton.
You'll want a tuner ($75-$200) and a rig ($200-800) and antenna ($0 - ???!). And misc stuff - coax, connectors, digital adapters if need be) ($50-$150) And of course the space to get your antenna in the air.
I started with a hamfest $200 FT-101, $60 eBay MFJ Versa Tuner, and a diy 40 dipole antenna. It was tough to learn and understand, but it was worth it when I made it though a pileup and someone in Europe, 5K miles away, talked to me.
Then I got into digital. With a tube antenna. More frustrations, but fun none the less. I've since upgraded to a IC-7300, LDG AT200, and another diy antenna. No more frustrations, just as much fun. It's a journey and more here are good eggs and happy to help.
Semi unrelated, I just made a contact into Brazil on 10M.

The smaller the Ohm, the better the performance. So a 50 Ohm cable provides much better results than a 75 Ohm cable.

Most home cell phone signal boosters come in 75 Ohm systems with 75 Ohm cables such as RG-6 with F-connectors.

Most commercial cell phone signal boosters come in 50 Ohm systems with 50 Ohm cables such as LMR400 with N-connectors.

I'm contemplating putting a tower up in a few years. I enjoy looking at the price of used towers on QTH.com and craigslist.
But how do I transport them? U-haul would be a $2-300 rental in most cases.

If you're questioning transport charges of $200-$300, a tower may not be for you. Building the base and ground system is going to be well beyond that, and this doesn't include the tower, antenna, or associated hardware. You will also need the equipment to climb the tower and install the antenna (gin pole).

I had a tilt design in mind. I can weld and would be happy to do as much labor as I can. $2-3K is fine for the tower and antenna - I'm just a few years out and trying to get a feel for things.
Probably just a dumb oversight that a u-haul/whatever is per mile and if the tower is x miles away ... Just kinda a 'gotcha' when I see these bargain towers for free or $500. I'm not just going to pull up in a pickup truck and be gone.

can anyone give me a clue as to the frequency range/usage for these antennae on my roof? I've come as far as to conclude they are all Yagi antennae. the middle one has dipoles somewhere around the lenght of 2-2,5m. Is it for analog TV?

Top and bottom are Yagi. Hard to see the size, but likely TV or radio. Middle is called a beam. 1.6M would put it around 80MHz - old tv.
1 meter or 2.8 meter in length would be ham radio.
You can adjust and mod them if you're so inclined

Are there general guidelines for folding a dipole over? I don't have the horizontal space for 160/80M, so thought I'd explore the vertical space. I've used a 'vertical L' with success before, but the misses wasn't too keen on a 200' wire zig-zagging all through the yard.
I recall things get wonky when you wind an element, but where does that threshold end?

Thank you! What is the difference between a beam antenna and a Yagi antenna? From what I understand a Yagi antenna is also a type of beam antenna, being that it's directional and composed of multiple dipoles in a row?
Another question, what is this box located inside my house? It connects to the coax coming from the antennae on the roof and to the output coax for what I assume is TV and/or radio. It also has a mains voltage input. I'm guessing it's either a filter or a signal amplifier?

I might catch some shit for saying it here, but respectfully, in your context and knowledge requirements, nothing. They're both good, directional antenna designs.
You box appears to be an amplifier, Hans. The coax is RG-6 which indicates it's intended for TV signals and not for ham use - but don't get discouraged if you want to. I'd be over the moon if I saw someone throwing those antennas away.

Thanks again. I hope I'm not shitting up your thread here, I'm don't really know much about HAM but I do collect old radios and I'd like to get a better understanding of how antennae and reception works. Right now I'm playing around with hooking up this old radio to the antenna on my roof and I found that the connections in the amplifier box for the shield wire and the core wire of the coax are shorted to eachother, is that supposed to be so or is something wrong inside the amplifier? Isn't the shielding supposed to be grounded and the core electrically separated from the shielding and ground?

Shorting absolutely defeats the shielding ;)
Is it Germany? You may be better off getting a cheap FM radio and playing with the connection using your ear as a guide.
If you have access to the antennas and interest in modding them or adding to the mast, I think there's potential to get great signals to the radio. If you have a few bucks, a NanoVNA would be able to tell you a lot.

Finland actually. The problem with new FM radios are that they don't seem to cover a very wide frequency spectrum on AM. And there's nothing interesting on FM. This old Phillips radio covers FM as well as AM between wavelengths 13-2000 meters, whatever frequency range that translates into it seems a lot better than some shitty new radio clock. Right now I'm tuning in to allahu akbar radio on 31 meters with pretty decent reception, although with a lot of noise and interference.

Is the interference more likely to originate from having the wrong antennae for the frequency or my shoddy connections/poorly shielded wire?

I'll look into the nanoVNA.

Although probably not as useful as the nanoVNA I'm more interested in older receivers so if you have anything suggestions for a decent/basic but functional old school reciever I could get of eBay I'd be very interested.

Commercial AM is around 0.8mHz
Commercial FM is around 100mHz
As you know, that radio is for 0mHz to around 30mHz
Your antenna is for 80mHz and 400 or 800mHz
Kinda like bringing a knife to a gun fight.
You don't need a NanoVNA, but if you're interested, it's nice to visualize where your antenna is tuned to, and if there are harmonics.
I think you're having problems b/c isn't not the right antenna. Kinda like going to your old car's antenna and snipping it in half.
Depends on how much time and effort you want to invest. It could be as simple as throwing a tiny, 20M wire on top of your mast.

I've tought about the idea of a wire antenna. One of the supporting wires of the mast seems to be about 20M in lenght, would that suffice as an antenna supposing I insulate the bottom/ground end so it has no contact to ground? Does the angle/orientation of the wire matter and should it be insulated or bare wire?

Kek. I'd be praying too if I were living there.
What you do depends on how much time and money and interest you have.
You're ahead of most of us as just receiving requires little material and has little danger.
You can play around and listen to the radio as you go and see if things get better
Or buy a cheap ($50?) receive antenna. It doesn't even need to be outside
Or get a NanoVNA and realize your (mast | gutter | ??? ) works perfectly fine as an antenna.
Or build your own. Keyword there is going to be shortwave hf.

I think the guy wants a standalone radio with a waterfall rather than a USB only dongle-type radio or something over network like a Flex. IC-7300 is cheap for a brand-new radio with a waterfall. IF taps and panadapters can give most boat anchor rigs a waterfall display too. ZL2CTM has a decent build for a standalone panadapter with a Teensy 3.5, mixer, audio board and TFT.

Be careful if you're buying a clone from China. Most of the boxed versions have missing components on that board that impact performance. The bare board version like pic related is regarded as the best of the clones but you'll have to sort out your own speakers/battery. For 55 Euros you can get a code to install the legit 2GHz firmware from the creator too which generally improves HF reception by having non-broken AGC.

2M FM will allow you to talk within your city or county, depending on transmitting power and setup. It will also allow you to pick up NOAA/emergency radio transmissions in your area.

The ISCOM IC-2300H (or any such ICOM) will best suit your needs for the price. Be sure to get a good power supply. However, for the most bang for your buck go with the Baofeng UV-5R. It is the go-to radio for /k/ for a reason. Very cheap, reliable, durable, and effective.

If you want to talk state or nationwide, go with HF. The 20 meter band is the most widely used, and is generally very reliable and useful; so go with a radio which supports that. However, it will be quite a large monetary investment, much more than an FM radio.

I'm not really a radio person, but I have some test equipment to calibrate and no accurate frequency standard to calibrate them against.
Somebody suggested I use the WWV 10MHz carrier as a standard, and that's a grand idea, but I don't have much working radio equipment except an Icom PCR-1000 SDR, and with a crude dipole antenna I receive absolutely nothing on 10MHz.

Before I keep going with this project, can I even expect to receive the 10MHz WWV station here in southern new england, or am I just too far away?
I saw a video (w2aew's #58) about how to zero-beat that signal by coupling the counter's oscillator into the antenna and watching the S-meter. This PyPCR software's S-meter is probably not fast enough for this. Any suggestions on that, if I'm ever able to receive WWV at all?
any advice appreciated.

I'm in the US market for a new or used vhf/uhf radio.
Just have a 2m TYT as a base station that I've grown tired of and would like uhf.
I mainly just monitor the air and occasionally chat. I wouldn't be against learning different modes or options. May get into satellite at some point.
Don't want or need the top of the line. With the cheap Chinese radios out there, it's going to be hard spending more than a few hundred.

If I do it, Euro bro, I'll spam it well in advance. Fucking kids, old car, and wife make nothing easy these days.
I'm 5 hours away fwiw. As gay as it sounds, I'm planning on hoping to try to do a new POTA
activation next month that's only half an hour away and taking a vacation day to do so - while hiding it from my parents who are going to babysit. If I skip that and go to Dan's, a gunshot in Tennessee may be hard to explain, along with telling my wife I drove 10 hours to meet a man.

Even if no collision happened this time, the route is set with all the trash put up into the orbit. It's hard to grasp how stupid it is to dump tons of TV satellites around Earth and allow launches for every piece of shit.
That's what I meant, when Kessler really hits we can at least hope there's so much dust up there that HF/VHF/UHF can reliably be reflected for DX. Can't bear the thought of having neither the perspective of a spacefaring race nor good DX condx.

"However, even a catastrophic Kessler scenario at LEO would pose minimal risk for launches continuing past LEO, or satellites travelling at medium Earth orbit (MEO) or geosynchronous orbit (GEO). The catastrophic scenarios predict an increase in the number of collisions per year, as opposed to a physically impassable barrier to space exploration that occurs in higher orbits." (Wikipedia)

So neither is QO100 "part of the whole mess" nor will the satellite contribute to it. If you want an artificial ionosphere you may consider using the Starlink fleet: SpaceX's Starlink program raises concern among many experts as the program's goal will more than double the satellites currently in Low Earth Orbit.

My artificial ionosphere will remain at an elevation of 29° and a safe distance of 38720 km.

Yes, even a repeater falls below the "human made infrastructure meant to transform ham radio to a glorified CB chitchat".

My biggest success, the youngest daughter got into CW for almost an entire afternoon. Wtf.
I'm now 54 and my large shack is starting to be a dust collection device. Ham radio is on the verge of literal extinction. If it wasn't for collectors, tubes and other historical hardware would be gone forever.

>Grandpa stories. He showed my brother and me how, as a child, he would prank old ladies from outside using a notched wood spool of thread pressed on a window or gutter. For a moment I saw the 10 year old kid I think Grandma always loved.
>He used to pay us to taste dog food. With a toddler who prefers eating dog food more than much else, those moments have made me laugh more than I should admit.
>He took us camping. And yard sale-ing. And reminded us to care for our feet, because our feet is what took us places.
>But these aren't stories. Finally one day it hit me. I can't remember when or where, but he said he listened to Germany from a clothes line. 10 or 15 year old me had brushed that off as either him pulling my leg again or him picking up crazy, invisible noise from a neighbor - maybe one of those new AOL CDs had caused all the confusion. Either way, antennas aren't clotheslines - antennas are commercial products with trademarks that you pay for.
>It took his death, 15 or 25 years later for me to draw the connection that radios and electronics were his livelihood and he may have been right. So I looked into it. No shocker, late at night when he claimed he could go downstairs and listen to German radio waves ... he probably indeed was listening to German radio waves caught by a little copper wire spread in the back yard.
>And in some way, that's really neat. With a little wire and box, you could communicate around the world without the need of internet or cellphones.
>So given all the technical changes of 50+ years, and not having to raise 8 kids, maybe instead of listening to Germany, maybe it'd be a good challenge, and fitting memorial, to try and talk to Germany.

>I looked if Grandpa ever had a callsign I could adopt. I poured over catalogued armature radio magazines and FCC documents, but came up empty.

Newb here, haven't taken my exam yet but have been messing around with my radio for receiving no transmission yet obviously. I have a Yaesu VX-6R. I had been using a Diamond antenna for listening to it. I strung up a roughly 29' end fed wire into a 9:1 unun and a 15' section of coax tonight to hear what was to be heard. I used no counterpoise, just the coax as a ground. I got much improved reception in the lower bands, could hear CB chatter from the interstate miles away and other previously silent stuff.

When I was scanning I picked up a local broadcast radio music station at 97.1 MHz. To my surprise I got the exact same broadcast picked up at 188.700 MHz as well. Further up the band I caught it again but weaker and noisy at ≈ 199 MHz.

What's going on here? I plan on running a 84' similar antenna with a 17' counterpoise I saw from a podcast notes from my second story up into a tree as high as possible. I don't have a tuner or anything yet, just listening until I get my ticket.

Don use a wire for listening to VHF and above. You're overloading the front end, of your radio, which is causing the false signals. Use a whip or an external antenna made for those bands. Save the wire for HF. Also, you don't need the tuner, balun/unun, or counterpoise for listening.

Knock yourself out. He's not transmitting, so a j-pole isn't the best listening antenna. I'd recommend a whip or ground plane for the interested band (if you want a resonant antenna) or a discone for broadband coverage of VHF and above.

In Japan, six months ago, the government approved a thing named "experience temporary station" that allows unlicensed people operate on-air.

The FB Girls ham radio group (callsign 8J3YAA) will promote the "experience temporary station" at Kita-Ogura Elementary School in Uji City (Kyoto prefecture) as an extracurricular activity for students, and in Ikeda city (Osaka prefecture). Under supervision of a Japanese ham veteran, JF3PLF, who got his license in 1977, the children communicated by issuing CQ from the observation deck of a small mountain near Uji during the trip day on October 2 and October 7. They operated an Icom IC-7300 with a long wire antenna, pushing out 50 watts on 7 MHz SSB.

I'm going to make a radial style dipole for VHF and UHF later because it is small enough to be able to go up high on my roof unobtrusively. I may try and make some vertical style antenna later but dipoles seem kinda like the low hanging fruit and from a physics perspective are ideal. I may try a j pole just because I do HVACR for a living and have lots of spare copper. Definitely will be making the VHF and UHF antennas out of spare copper tubing that has gotten too hard to be flexible. Not really a priority though as the diamond whip antenna has performed fine for those bands already and I don't own another transceiver.

Pretty cool seeing what a simple wire could drag in. I was able to here rebel radio out of Havana, a station for world christian broadcasting out of Nashville and a univision broadcast out of Connecticut. Both were about 700 miles away!!

I should have my ticket soon though as I test in about a week or so. Can't wait to get on the air.

I've been around for around a year, and agree contests are a PITA. Too many pileups and over-enthusiastic folks. But it would be nice to know if I can answer their call and what my duty is to allow them to succeed in their ventures.
The CQ World Wide DX Contest kicks off in a few hours. I'm trying to weigh the pros and cons of trying to answer a 'cq contest' call. Would logging to LoTW suffice? Would I be chastised for not having a CW membership and/or not filling out a 10 page contest log?

I wouldn't bother replacing it. I use a bioenno battery (mostly at home). Just make sure to have an inline fuse between battery and radio. Car battery should be fine.

Also, qrpguys has an efhw antenna kit that is relatively cheap. Nice small project while you're waiting to get licensed.

What scanner antenna has the lowest SNR for shitty RTL-SDRv3.

I tried making a colinier ADSB out of coax with a crimp on connection. I did 4 elements right around 4.1 inches & didnt have much luck....Going to buy some solder.

Any pitfalls you can help me avoid a week into HAM?

That antenna looks neat, saves the tuner which is adding bulk. But that would lend to replacing the internal batteries again. I'll think that over. The FT is an awesome rig, I will definitely keep it.

Currently using that efhw out my second story window. Slopes down to about 7-8ft above the ground. ~20m wire gets me on 40m at <1.4 swr and 20m at <1.6 swr.

Recently had a js8 contact from en91 down to el88 on 1 watt. WSPR gets out to Germany on 1 watt with this setup.

In the near future I will probably build a better transformer for the efhw. Would also like to experiment with a l-match tuner on the same wire.

I'm in an old city neighborhood and this has been a good compromise setup so far. I should string something on my roof but gawd that thing is steep.

How high is your dipole off the ground?
If you haven't already, move it to 10 to 15 feet off the ground. Place an untuned insulated wire a little longer then the entire length of the dipole on the ground under it.

It's around 30 feet up. By some dumb luck, it's resonate from 6 to 160, so I'm not screwing with it.
Maybe I just need to temper expectations - one 100W SSB call on 160 or 40 isn't going to blanket the entire US.

Drop it down to 15 feet off the ground. (Your antenna is on a pully right? :) )
Lay a ground wire.
Make the contacts and raise it back up.

By lowering your dipole you increase the angle of radiation.

Being a state over, you might want to try leaving the antenna at the same height and try
80m.

I'm leaning more to misguided expectations. Hitting a button on FT8 nets me a visual map of all the people that hear me. On SSB, I call into a pileup and get disappointed after a few attempts, never knowing if anyone heard. I've been at it on and off for a week and gotten 4 close by states on 40M, so I'm not entirely up the creek. I need more free time to play!
