CB. FRS if you wanna talk to the kids in the neighborhood.
but seriously, the name on a list thing is pretty lame. at least its one that you have control over, which really means who gives a shit.
what bad thing has happened to ham because hes on the FCC licensed list?
all i can think of is when people become nuisances.
honestly the mentality kinda reminds me of nutnfancy's ham radio episode i saw years ago. he had some random HF base radio, no real accessories, no real knowledge, no license; because he doesn't want to be on the govt list.
the guy who buys massive amounts of weapons, armor, explosives, makes very public youtube videos with them including blowing up random shit with tannerite. is/was a county sheriff, so everyone in the country knows who he is and where to find him at a quick web search.

Hey radio folks, my family is getting an RV with lots of rooftop, and I have been given the green light to get as crazy as i want (I told them doing the work myself, buying top shelf everything could cost over $5,000) adding 2-way radio comms to the RV. I have been digging around doing research and I have come up with a preliminary equipment list I wanted to run by you guys for your opinion.

Ranger 2970N4 12/10 Meter Radio (Some of us have technician licenses, couple generals)
President Thomas FCC CB Radio
Midland MXT500 GMRS Radio (We have GMRS licenses)

Icom IC-7100 dedicated D-Star Radio
Yaesu FTM-400XDR dedicated System Fusion Radio
33cm - new to this band, looks like converted motorola commercial mobiles on ebay.
For 6 meter, 2 meter, 1.25 meter, and 70cm I need to do more research on what my best options are for power and features.

That's a fair point and question on practicability.
I'm concerned about desk space.
Right now I have 2 power supplies, ic-7300 and 2m/70cm radios, swr meters, and amp so I can hardly fit a keyboard and mouse on the desk too.
Separately, I have a NAS (basic network server for backing up and movies aka 'the cloud!')
I'm thinking in the next 5-10 years of combining it all into a clean, in-wall server frame and perhaps have PC controls. I mainly make HF contacts and scan VHF/UHF.
That'd allowed me the flexibility to add even more radios, perhaps a separate listen/TX radio with a beverage antenna, and more VHF/UHF and grow my NAS addiction.
Or maybe that's a lost cause and I should get a bunch of raspberry pis and RTLSDR and focus on an antenna farm.

Check the web for info about this. There are lots of tips/pitfalls to check for. One of the big pitfalls with RVs is the lack of a suitable ground plane on the body. So half-wave antennas (and others which don't require a ground plane) are key, similar to fiberglass boats.

Oh wow that's crappy. They haven't picked one out yet but they're looking for a barely used 40' RV/Motorhome. I guess they all have fiberglass roofs?

I actually WAS wanting to get a full wavelength NMO for each radio. i wonder how much trouble it would be to lay aluminum sheeting in the roof when the ceiling is out to run cabling.
aluminum sheets can be had in various gauges from sheet metal distributors, quick search showed 1 company advertised maxing out at 6'x 20'. i bet i can get someone to cut 40' off a 6'+ roll of something between 20 and 30 gauge.

I recently installed a CB antenna in my apartment, basically a long aluminium arm at the end of which I put the antenna base, which is a radial radiant and a vertical radiator (https://www.thunderpole.co.uk/base-cb-antennas/sirio-boomerang-a.html).). Pic rel is the big version, which I swapped for that in the link

My problem is that it's a bit too close to the building's roof (next floor up) and because of that I get rough SWR readings on my radio (about 1.8) and I sometimes cannot copy people which can copy me.

The solution would be to install it on the building, at the top, but if it's found out I'm getting fucked big time. I can, however, set it in lieu of old TV aerials which are unused now. Would probably need a digital means of collecting RF from rooftop to my apartment.

The carrier and one sideband are suppressed by filters before it goes into the final, that's how you save power for just that one sideband signal.
The receiver needs a beat frequency oscillator to mix a carrier into the received signal.

Not really how it works, you're putting the cart before the horse, it's a lifetime hobby about learning and most don't manage to learn jack shit. Reading theory is useless, just pick something and do hands on. There's a library in the OP thread also.

'I just want to build a receiver'... Yeah, good luck finding variable capacitors. Look at the QDX/QCX kits for inspiration otherwise you're going to end up studying about steam engines when the only parts that exist are for fuel injected gas cars. Plenty of electronic stores here but god help you if you try to build a receiver using the parts they have available, the legacy parts are super rare which is what all the 'theory' talks about using.

As I said, I'm doing my major in electronic engineering and you really cant just "do hands on" in most circuits, it actually gets even worse when dealing with analogic stuff.
There must be sources or something with the actual electronics, It's just really hard to get.
I highly doubt all those cheap chinese kits were actually designed by the manufacturers. They usually just copy the schematics from somewhere and call it a day.

The signals at regular intervals could indicate you are overloading the input. Is there a strong broadcasting station nearby? An attenuator might improve this, better yet add a broadcasting band filter.

[Anonymous No.2413160]

>>2413147
Dunno what else there is to say. I meant tru(sdx) not QCX. Play with HF, the parts are big enough for 'hands on'. Pick some silly project schematic you see online and build it. I'd recommend getting on the air with HF before bothering with any of that.

As I said, good luck getting variable capacitors. Any 'theory' book is going to reference parts that haven't been made in 50 years. The real-world designs are ways to hack what exists today into something usable and those designs will be obsolete in 10 years when those parts no longer get made.. Rinse, repeat..

Every design is pretty much going to be using a PLL and probably a microcontroller. Gone are the days of variable caps, variable inductors and crystals, instead we have weird hacks to get around using such expensive legacy gear.

You can have some noise from a wall wart and that's it, if it can deliver enough power, it's ok. another thing to consider, most HAM equipment want 13.4ish volts to deliver full power when transmitting so at 12V you'll have less output power.

Standby generator or battery bank + inverter (a la solar style). I wouldn't bother bodging together ups units. The thing about ups is they can only handle so much current draw, even when not running on battery. I had a small one on one of my computers that would alarm whenever I put it under heavy load. Sure, you can add larger batteries, but that doesn't increase the current draw limit. Run time will be extended and recharge time too. Most of these supplies are low rate dumb chargers that take 12 - 18 hours to charge an 8 Ah battery.

Use a UPS that can deliver sufficient power, with enough energy that you have time to start your generator. Around here you can get statistics for power failures, a 3 second blackout is a pain but not long enough to need a generator.

I think any of the high Z shortwave receivers are going to perform about the same. Tecsun PL-380 is about $50. If you want full range or SSB then you'll spend more.

I don't think the 'desktop' variety receives offer all that much more, for that price you're also bumping into the range that a Xiegu X90 costs. A xiegu doesn't have a high Z input however so a dedicated receiver would likely be better for the same antenna.

One of the multi-input SDRPlays might be a good option, they have phase control which can act as noise cancelling, but that's on the low-z 50 ohm inputs. They also have just a single high Z input but you can't combine that for phase noise cancelling.

IMO I'd try to get one of the Belrig receivers. https://belrig.by/

OK then. My question has now become: Did I choose wisely in those 2 models or should I be considering any other radios? As far as my limited research as shown, those are the best 2 handheld receivers/scanners on the market atm.
The only thing I'd be missing the ability to listen to would be system fusion(which would be solved with a Yaesu dual band HT, or not caring), or standards that don't exist on north america(which don't matter for my use case), and encrypted & cell phone data, right?

I am currently putting a field portable computer using a raspberry pi 4, a touchscreen, and several SDRs for ham use. It will be built into a Seahorse SE230 case. TX will be handled by RPiTX and related software to transmit using the GPIO pins. I have the panels made up from steel sheet metal. All of the software I have wanted to use is working, and I am currently testing with the HamPi (W3DJS) June version of Raspberry Pi OS. I tested it with 10 18650 batteries and it lasted through a good night's sleep and then some with the screen on and turbo mode on in the config file.

I have an Airspy mini as its 6mhz of bandwidth is about as much as the pi can handle. I did experiment with an RSP1 clone but using its full 10mhz was a bit janky and it is a lot more of a paint in the ass to get SDRPlay products to work with the pi. (Airspy and RTL-SDR have easy to use aptitude packages.) I have an Airspy HF+ Discovery for HF reception, and it will have a pair of RTL-SDR v3 dongles with synced clocks.

Part of the blank area to the right will be cut out for a recessed area where I will have 5 BNC connectors, 2 HDMI plugs, 2 USB3.0 A connectors, 2 USB 2.0 A connectors, a USB C for charging only, a 1/8 inch audio jack, and probably an RP-SMA connector for a wifi card with pack injection/monitor mode capability, and possibly a second for the built-in wifi if I can mod the board for a mmcx connector or something. On the bottom I will have 2 little speakers hooked up to a wifi amp and some switches to shut off various components like any peripherals not in use. It will have a Vortex Core RGB keyboard and an ergopad for input.

The inside will be lined with copper tape to reduce noise. It should be a good little SIGINT box capable of SWLing, AM/FM/SSB/Almost every Digital mode as well as GSM sniffing, Wifi pentesting, Satellite reception, ADS-B, WSPR, ACARS, Pocsag, Flex, Weather satellites, P25... the list goes on forever. Plus it is QRP capable in many modes up to 1500mhz.

[Anonymous No.2425969]

The antenna connectors will be on the panel where the display is located, to the right of it. I would put holes in the case and run them through to the outside but I don't want to compromise the waterproof integrity of the case. I will also probably put metallic foam rf gaskets around the bottom so it is somewhat EMP shielded from all directions. The idea is to have it be as rugged as possible for field use. I will probaby use butyl rubber caulk and waterproof connectors to make at least the top part waterproof. I bought my pi when they were $75 and now they go for $200 due to scarcity and scalping so I can't afford to have it die on me due to water damage.

Copper will prevent RF leakage but will reflect it back to the computer. Some computers are sensitive to EMC, one Amiga model wouldn't even work outside its box.

I am surprised not modern ham stations can be accessed from the net in listening only mode, just like KiwiSDR radios.

Thing is, they eat up enormous bandwidth. Start recording an SDR, then play it back through your SDR software. You can change frequency and hear things on frequencies you weren't even listening to.

You can handle bandwith issues in several ways, either pump the full incoming baseband to the net, or just the range of the ham band that the guest user is looking at. I think KiwiSDR uses the latter when doing ToA.

Putting otherwise idle receiver onto the KiwiSDR net for DF or lightening ToA would also be useful.

If by "repeater" you mean relay, you need filters if you want to emit on the same band you receive. Very strong filters, so expensive stuff, plus the thing you show is professional oriented gear.
My club manages two relays and they were cheap, but a ot of work went into them, the receive and emit stages are indeed VHF or UHF radios and the filters were found somewhere.
If you want a "repeater" so something where you talk for 10secs and it repeats these 10 secs on the same frequency, you need a radio that does that or a way to record, stop receiving, start emitting (vox can do it) and the voice memory.
Then for crossband relay you just need two radios with vox and two antennas or one way diplexer
two UV-5R can do some "repeater" but I never try so I don't know if it's relay or repeat
