It’s a little known fact that H.A.M. is an acronym for “Hounding Anonymous Men.” No, that’s wrong! It isn’t an acronym at all.

No, not always, but I try to be accurate. Like anybody I’m far from perfect.

It’s just the choice some manufacturers make. RPT15 is exactly the same as 23, RPT16 = 24, etc. Personally I prefer using 23-30, instead of RPT15-RPT22, but it’s the same thing RPT15 (aka channel 23) receives on the same frequency as channel 15, but transmits 5 MHz higher.

One thing that I like about the Brendan Carr nomination is that he is already a commissioner. Regulations are some of the most complicated things there are in government and bringing in an outsider who has little experience exponentially adds to the burden for the people who do the actual work.

Welcome, Mike! There are a few other threads based on your level of expertise. Feel free to ask questions!

What does it sound like in AM mode?

No, the frequency 467.550 is not solely allocated to GMRS. Look at US287 on page 153 of this document: https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf

That’s correct. When you specify TSQL you send a tone to the repeater and you filter out any transmission that you receive unless they match your receive tone.

If they refer to it as a tone, it’s CTCSS, but the decimal makes it certain. When a different tone is listed for receive, you can always just leave the receive tone empty. If you do use a tone for receiving, there are only two choices that make sense for Squelch Mode: Tone or TSQL. The difference is that TONE means you send a tone to open the repeater but you don’t filter on the receive tone. TSQL means you send a tone to open the repeater and you filter received signals, breaking squelch only when a matching tone is received. DTCS is only used when you send or receive digital codes (aka DPL).

The DILA repeater on 550 has no output tone. I replied to your other comment with that information. The Mt. Wilson repeater on 600 has a tone which is indicated on its information page on the mygmrs repeater page: https://mygmrs.com/repeater/4553

Did you look in the repeater database on mygmrs.com? It says there’s no tone on the output: https://mygmrs.com/repeater/5216

It looks like it’s just the same as a UV-5RM. Here’s its manual: https://baofeng.s3.amazonaws.com/BAOFENG_UV_5RM_PLUS_User_Manual_EN_20240304.pdf

It’s a single band UHF antenna so I wouldn’t expect good transmission from it. Without measuring the SWR it’s difficult to say. Maybe someone who has both an analyzer and that antenna would measure it. I tried using an MXTA26 for 2 meters and a friend six blocks away couldn’t hear me with 20 watts.

Also, @Billz, many beginner level questions have been asked in the Guest forum. In fact I wrote this post as a bit of an effort to help people who are new to the forum and asking some of the more common questions:

Welcome to the forum. There are a lot of us here who got started at a later age. If you enjoy watching videos there’s a YouTube channel called Notarubicon that has a lot of basic GMRS knowledge videos. There’s also an excellent video on this forum by @marcspaz that’s an introductory level. I’ll see if I can find a link. Here: If and when you decide you would like to learn more about ham radio the concepts you learn here will help. I can also recommend an online study site that’s free (although you can buy their app for your phone for less than the cost of a beer at a local bar.) It’s called HamStudy.org. But most of all feel free to ask questions. There’s one guy who tends to scold some people for asking questions but he is definitely unlike anyone else here and it’s easy to add him to your ignore list. And sometimes he surprises me and offers good advice. Again, welcome!
