I will bet dollars to donuts that the reference to "chirp" was a typo or auto-correct mistake.
Don't hold your breath for Chirp support on the DB20-G; is just not gonna happen.
Historically, narrow-band GMRS repeaters are used as private repeaters, or with semi-private portable repeaters used off-road for compatibility with easy to purchase FRS HTs.
When repeaters are stationary and open, they are normally set to wide-band.
Even Midland recognized that the times, they are a'changing!
l create code plugs for each Mode.
When opened, all 500 channels are available for TX. I posted somewhere here on this Forum in a GMRS thread, my codeplug for Part 95E rules when opened.
There is one specific radio, the Radioddity DB20-G a/k/a Anytone AT-779UV that comes Part 95E certified that can easily “open” to use on Ham 2 meters/440 MHz and then reset to certified use on GMRS.
I have and program the original Radioddity GM-30 clone, from Pofung, which requires a Windows computer for programming, but no experience with the GM-30 Plus.
What is the "Bank assignment?"
I easily power my DB20-G with my Jackery Explorer 300.
I do have a 120v AC to 12v DC main power supply for longer term use. It is the JetStream JTPS32MAB, which I purchased years ago from the old HRO that was located nearby in those days.
I stopped buying every new cheap HT that was being released some time ago.
I will let those with specific experience of the baofeng ar-5rm help you now.
Good luck!
Try this:
Go to Channel 25 (or it may be listed as Channel 17Repeater) and enter the Tone of 123.0 on your output (transmitting) side only.
Go outside and/or drive closer to the GCR 600 Perdido Beach Repeater and transmit a "repeater check" and ask them if anyone can hear you.
Good luck!
UPDATE: Or Channel 28 (or Channel 20Repeater) and same 123.0 tone for the GCR 675 ORANGE BEACH Repeater and try that.
Also welcome to this forum!
And welcome to GMRS 10 days ago
Please do not be discouraged by snarky responses to “newbie” questions; it’s part of his charm!
Good choice of Radio: I have two - one for the car and one for the shack.
I will leave out my selection of power supply, as I find the prior discussion confusing and I do not have wide experience in the power supply area.
I have a $19 mag mount on my car and a Comet CX-333 on my roof
This radio outperforms the Yaesu FT-857d when it comes to FM.
I don't know who @LeoG is, but that post in X has already been debunked by the Republican officials in Kentucky:

And it would not surprise me to finally hear that "Nick Sortor" on X is either a Russian Bot located in St Petersburg, Russia, or funded by them to spread this information:

"Let the Buyer (of internet 'information') beware!"
I have no experience with them, but many claim that the Anytone AT-778 and its Retevis clone are CHIRP compatible.
I suspect given the serial protocol problems listed on the CHIRP thread, the DB20-G may never be CHIRP compatible.
I keep a library of different CodePlugs for various uses; most famously a GMRS Part 95 compatible one for when it has been "opened"
Yes, the UV-21 appears to be one of those new-fangled dual vfo screen HTs; none of which I have any experience with now, nor do I expect in the near future. I am pretty much maxed out on GMRS radios for my use case.
It could be that Baofeng software for these radios will not run on Windows XP and may require Windows 10 or 11. Did the programming cable come with your purchase of the UV-21 or are you adapting one from another radio?
I would suspect that this radio will get CHIRP support sooner than later and that will work directly on your M1 Mac.
What's your radio?
I was always a Mac Guy in a PC, then Windows World, so I got to know how to co-exist!
When I had my iMac G5, I ran Windows with either SoftWindows or VirtualPC; can't remember which. It came preinstalled with Windows XP.
I extracted that copy of Windows XP and with my Microsoft License, I have used that copy for about 20 years now in various installations of Boot Camp and Parallels to program those radios that only work in Windows.
Having Windoze only radios that need programming and only having a Macintosh, I use the Parallels virtualization program to run Windoze concurrently with the MacOS. There are other virtualization options available, some free, but I have been a Parallels user since my first Intel Mac back in 2006 and familiarity does not breed contempt in my case!
