Why

That all checks out to me. Install it, run it, and decide if it works well for you. Don't see why it wouldn't.. Stay with lower gain mobile antennas. I'll be the only one on here to tell you that probably, but trust me. Or actually TRY both and see for yourself. Everyone else is just reciting ideas.

k..

Well that's about all I'd hope to achieve with a power supply. In my case probably a 20-25 watt radio at most and maybe use the front receptacle to power a desktop receiver I have.

I decided I needed a power supply to grow with that’s higher in amps. I found this one on eBay and ordered it, but know nothing about it. Very little info exists on the internet. Just curious if anyone here was running one and what you think of it…

No man . The point is that I’m not doing that. It’s real life out here. If you spend any amount of time off of UHF FM. AM mode on VHF and lower. It’s noisy. The FCC isn’t going to show up in FCC vests and kick in any doors if I complain about anything. We do loops or do out best to set our wire back far on large properties if we have them. RF urban noise has just become a part of the fight.

We have this new 2020+ problem where us two people don't see reality the same.. I read the plain text of 15.5, and I reed gud. I have no idea what part of that says anything resembling what you're talking about..

Now listen,.. If I had a neighbor a house or two away from me who was doing radio as well, and he mentioned that he thought I was doing something that was giving him noise on something. I would ABSOLUTELY do what I needed to to squash that. And then he's also my new radio friend. But aside from that sort of circumstance. Nah..

So when I want to listen to 780 WBBM on my kitchen radio every morning with coffee, but I get the hashy noise because I have a neighbor with the cheap Chinese switching power supply, 15.5 says "sorry bud"..? I think I'm actually encountering "harmful interference". Any radio dork here who also likes to receive the HF/Shortwave band is a victim of it.. By the vapid population who surrounds us, who also don't realize that they're violating FCC regs. My point is,.. We who do the radio, should be the ones to curb our ability to do so, so that these goofs don't hear any noise? Even though they don't know the difference between radio or Instagram? K..

Read 15.5 to YOURSELF. slowly..

Yeah man.. a wireless pad phone charger isn't an authorized or intentional radiator on 780am, is it.. And it's not industrial, scientific and medical (ISM) equipment.

I don't get it..

Yeah you too

I don't pretend to know the FCC codes front to back, so I looked that up. https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-15/subpart-A/section-15.5 I'm also not a lawyer. But I don't even see what part of that makes it so that I have to just DEAL. Man whatever. Not trying to start fights with goofs on here any more. Maybe you just didn't think i'd look. You'll "quote FCC rules" and I should've just been like "whoa, the important man has spoken". Go jump in a lake..

Good lawd.. Ok god bless you...

Everyone out here these days is making Aliexpress NOISE. But since I know what radio is, I gotta be the one to pipe down?

Hey do I get t bit*h when my neighbor over here has some Chinese wireless pad phone charger that's putting hash all over my AM? What authorities do I need to notify?

You think so? Those people who are just doing their vanilla life thing watching TV and stuff? They're going to have their spectrum analyzers out just friggin policing the RF floating by? Hey I'll tell you what.. When I get that knock on my door from that neighbor I just made a new friend anyway..

I wouldn't, because I know how this stuff actually works in practice. Especially on Terra Firma. 50mw will get a block or so away on UHF, and as an "untoned" signal, it's not getting into any public safety systems' comms for example. I use a HackRF with a 20mw transmitter as a piece of test equipment. If I barely leave the room with it, it's ineffective. 5 watts is 5000mw. That's,.. not the same. Also there's that whole ABSOLUTELY pure line of sight that sat comms enjoy. Yes 5 watts will go into the sky forever. But it won't leave your neighborhood past the dirt hill 2 miles away..

Spurs on harmonics, even on the dirtiest Baofeng aren't a factor, They're 50mw worst case scenario, and they aren't going to bug anything of significance.

I've got 1 Baofeng UV5R in particular that I bought in like 2013 and it's been my "knock around radio" since then. It was cheap and didn't care about it getting ruined. It's the one that got wet, dropped, given to people I didn't trust (), etc.. Guess what, it STILL serves that role after 11 years. The only thing wrong with it is that the backlight doesn't work anymore. I'd say I got my $17 worth in 2013 dollars. So, as far as "Chinese crap radios" go. That's a case study. I was an early adopter of these things and I'm still waiting for one to not turn on and work, even after abuse. The hams will get upset that they have harmonics. Whatever. The batteries are even pretty great. Charge one up and don't turn it on for a year, and see if it doesn't still have 4 bars when you do . It's a great radio for the "emergency kits". Nothing wrong with doing a Chinese radio thing. They do the radio thing.. And maybe they're not "as good" as some $150+ radios, but the law of diminishing returns kicks in real quick after $40.

No it's like a whole other thing. The Quansheng UVK5 series radios have user flashable firmware capability from the USB-C port so a whole little community of developers on github are developing new firmwares that really improve and open the radio up. There are some videos on Youtube about it. They're $30 radios like the Baofengs are, so it's just become a fun little side bar hobby to get one and play around with these different things people are doing to them..

Sounds like a ton of fun. I'm jealous. You'll do fine with GMRS radios of any measure on your property. If my mental image of your agricultural property reflects reality it's going to be no problem for a kit of straightforward HTs doing simplex. Maybe all choose an agreed upon frequency and a tone as a family, just to sort of have "a private channel". If you want to get a repeater up to get off of the farm and into town, just do that Retevis thing and make yourself a nice mast up high somewhere. It's all about height. Higher the better. If you want to get out further, figure out how to get it even higher. Don't sweat radio power. It's the most overly discussed aspect of things on UHF radio, and it's almost not even a factor. 5 watts up high beats 50 in a hole all day long.. Another option for an ULTRA cheap repeater is a simplex repeater. It's just a real simple deal. It's a box that connects to a radio that you just set out somewhere (again, preferably really high), and it'll just sit there in the middle of comms, and record everything said, then spit it back out afterwards. They can be annoying if you're in range to hear both transmissions, but they do work very well and the simple nature of it means there's not much that can fail. Easily and quickly deployable for temporary type things. It could be a short term option if you don't want to spend on that full duplex repeater box quite yet.. You could get all of this done on just a couple hundred bucks worth of Chinese stuff..
