I’m not sure. The trunking systems around here don’t use that kind of antenna.

Yes, if you set a frequency with no tones and another GMRS (or even FRS) radio goes to that same frequency you will be able to talk to each other. All GMRS radios should be capable of tuning the frequencies you have with GMRS in their name. All GMRS radios are capable of using simplex.

Because 10 codes are in common usage and don't hide meaning.

Prohibited GMRS Uses: (3) Coded messages or messages with hidden meanings (“10 codes” are permissible); It's very clear. "No one knows what the codes mean except us" literally means "Coded messages or messages with hidden meanings."

That's exactly how I would understand it.

Yup, cell phone antennas.

It is rated at 10 watts, but I still think you’ll be surprised at the slight difference in range. Urban areas are difficult. Are you planning on using it on GMRS? Or maybe I ought to ask how you’re planning to use it and what kind of range you hope to get? On the seven interstitial 462 MHz channels you’re limited to 5 watts on a handheld. On the seven interstitial 467 MHz channels you’re limited to 0.5 watts PEP. I would be looking at something like the Wouxun KG-935 for GMRS.

Not usually. Possibly in thick vegetation, but it’s really not enough extra power to make a difference for most circumstances. In free space quadrupling the power might get you twice the range. Free space means there’s absolutely nothing between the two stations. UHF is primarily line of sight and increasing power doesn’t change the curvature of the earth or remove other physical obstacles.

One of the things that you’ll quickly learn, either by recommendation here or by use there, is that power is highly overrated as a predictor of range. A good receiver that has both sensitivity and selectivity and a good antenna are much much more important than getting an 8 watt output radio versus a 5 watt radio.

That’s not inclusive!!! You must say “Radiosy Radios”.

Not the same kind of map, but a very comprehensive listing is at repeaterbook.com.

That’s right, double down by blaming your mistakes on others’ courage. As @WRQC527said, it had nothing to do with courage. It doesn’t matter if it has anything to do with sexuality and frankly that thought never occurred to me. Your choice of words was insulting, just as you intended it to be, and like every other intentional use of nicknames to put others down. By the way, you might want to take it out of your signature.

What kind of traffic were you hoping for?

That’s not enough information. Are you talking about the speaker output? How are you generating the tone?

Except that you have now announced in an online forum where you store your keys. If you want to delete that part of your post, I’ll edit this post.

That’s the “Hello, World” of two way radios! Good job!

A friend asked me to fix his MFJ 269D Pro. I fixed it yesterday. Someone had broken the N female socket on the top. That was not designed to make it easy to fix!

It’s like speakers for an audio system.

The meter arrived today. Stupidly I didn’t order a short (about 18 inches) coax jumper; don’t be me. So, I used a 12 foot ABR 400 cable. It appears to work just fine but I have no reference. My Radioddity DB20G measured 18 watts at 146.940 MHz. At 147.500 it measured a little over 20 watts. A digital meter might’ve reported more figures to the right of the decimal, but I don’t know that it would mean anything. The SWR of my Comet SBB5 antenna measures 1.1 at 146.940. That’s the frequency of our local repeater. Again, that is meaningless as an endorsement of the meter without a reference of some kind. The only negative that occurs to me is that it seems small. I didn’t pay attention to the dimensions.

And this site explains what those three characters each mean: http://fcclicenses.blogspot.com/2011/10/fcc-emission-designators-what-do-codes.html TL; DR: So, for instance, F1D means Modulation type: F Angle-modulated, straight FM, Nature of modulating signal: 1 Digital, on-off or quantized, no modulation, Information type: D Data, telemetry, telecommand

Although I don’t have this particular radio, it just wouldn’t make sense for the manufacturer to do that. I tried searching for “cloning Btech GMRS Pro” but came up empty. Sorry.

But do they have FCC ID labels or are they just for the export market?

Unless you put the repeater someplace where that 300 foot hill doesn’t block your signals, it’s not going to help. You might have led with that information.

I don’t debate politics on this forum.

Feel free to use the ‘h’ word in all its variants, but quotes are not necessary. I had a friend who was a drafter who always had his caps lock key on for text on drawings. He would get on email and folks cringed because he was always yelling.
