But if anyone else is using it under a different license, or if anyone using it doesn't identify, the repeater is supposed to. Of course we know there's really virtually no enforcement in this area, but nevertheless, people often like to try to do the right thing. Why Morse, I can see two reasons: First because many repeaters can do that automatically. Second, because cognitively, Morse is out of band from human speech, and therefore less intrusive, less confusing than a spoken voice coming through at 15 minute intervals interlaced between the primary voice communications taking place on the repeater. This concept derives from the Gestalt Psychology's Law of Similarity which suggests that visual processing benefits by grouping similar things to have similar appearance, and different things to have different appearance. Software developers try to make similar concepts in code look the same in code, and different concepts in code look different, as that helps developers spot things that might be incorrect, missing, or out of place. And user interface designers attempt the same thing; browser buttons on a website should have visual similarity when they do similar things, and other elements should be visually distinct or dissimilar when they do different things. It helps end users grok a user interface more readily. Our brain processing language and sound benefits from the same considerations, so it makes perfect sense to keep rule compliance interruptions out of the cognitive load of the actual primary conversation.

Thanks, Steve. Always a great resource!

Gregg, I’ve done a lot of DMR codeplugs using native CPSes, RT Systems, and GD77. I think I have a pretty decent understanding of it. Feel free to reach out to me anytime. If I haven’t already given you my cellphone number I sure will. Steve

Have to look at home. Work 'pooter won't let me access. But sure, I just got the 3800 MillerAmpHour ones for $15 a pair...

I am sending this one back! It requires unscrewing and screwing the two screws each time.

Congratulations! Get your easy to pass Tech soon. Look for an available DM-32 codeplug from a local Ham Radio club to modify for your needs. That is easier than starting to program one from scratch.

Yes, I am having the exact same issue. I happen to also be a couple miles from the repeater I’m trying to hit. This is happening with all 3 of my ailunce ha1g radios.

How does one get into the training program? I’ve joined the discord and it is really cool. I hope more users join that as well.

The attached file should help. Amateur Radio Guide to DMR.pdf

This landed on my porch today. Now I only need two things: An understanding of DMR, whatever that is, and A license Other than that I'm good to go. (I know, I know, don't push that button.)

Thanks. This one then: https://www.amazon.com/BAOFENG-Battery-Capacity-Charging-Extended/dp/B0DM8W5MTH?th=1

If it works on the older UV-5R, then NO.. If it works on any of the newer/bigger ones with the color screen, then, probably.

Is it safe to assume this will also work on an AR-5RM?

It's the repeater identifying the license under which it operates. At least that's by far the most common reason you would hear Morse code on a GMRS repeater, and the only Morse I've ever heard on a GMRS repeater. In Amateur radio you may hear CW (Morse) beacons which send out a call sign plus location and power information; CW for realtime communications; Morse identifiers on 2m or 70cm repeaters, so many other use cases. But for GMRS is nearly always just a repeater identifying by the license of its owner. Here's how you can know, though: Record the transmission: Use a VOX recorder plugged into your radio, or plug your radio into your computer and record with Audacity or some other recording software, or use an SDR and SDR software with recording capabilities. Trim down to the relevant section of the recording using Audacity or some other software. Reduce noise using Audacity or some other software. Upload to one of many websites that will transform audio samples of Morse code into plain text. Once you see that it's a call-sign, use the FCC tool to look up the call sign's owner, if interested. The whole process takes just a few minutes and can be kind of fun to work through once or twice.

Many repeaters have the ability built in so it’s fairly easy to configure. Sometimes (especially on digital repeaters in ham radio) the Morse Code ID is sent without CTCSS tones, so those who use a receiver tone do not even hear the repeater ID. Personally, I prefer a repeater that IDs using a voice ID because I still haven’t trained myself to copy CW, but as long as the FCC allows Morse code to be used it will be.

There are still hams mad that CW isn't required anymore to get your license, so.....

get another 50 years under your belt. you need it

Is there a reason that one would choose to do this? Morse Code, in 2025?

Yup, my setup is a bluetooth device and the microphone. So using 2 microphones on a splitter may or may not work. It's doubtful it'll damage anything so if you try it the worst that happens is you spent $10 for a splitter you can't use. There's always the chance of damage so don't listen to me. . .

Can always count on Mr Shannon. /salute

You leave your expert opinions out of this!

And some use both!

PL tones are all over the place here in Missouri with 100.0, 127.3, 141.3 and 156.7 being the most commonly used tones.

Very good point ! I see it mostly in reaching out to other Trail Leaders when trails are being used used by several groups.

123.025 MHz is air-to-air for helicopters
