CHIRP

From what I have recently read, the Retevis RA25 is also the same radio.

I've requested an RA25 from my contact at Retevis. I'm waiting to see if she honors my request.

I have an AT-779UV on loan and am looking at the protocol.
First thing that seems different is the expected baud rate (115200) (and no echo);
the program response is different (just \x06);
it sends a four-byte read command instead of three, I'm working through this manually in Wireshark so far to get a general idea, hoping to script up some tests soon.

I am also interested in having the Anytone AT-779UV working with CHIRP. Let me know if I can provide any resources to this end. MichaelLAX at AOL dot COM

NOTE: In my experiments: code plugs from Anytone AT779UV and Radioddity DB20-G are interchangeable; but they will not load into the Retevis Ra-25 software, so there seems to be something proprietary about the Retevis software.

Extremely popular radio: Radioddity DB20 - AnyTone 779UV - Retevis RA25

According to FCC info, the Radioddity DB20, Retevis RA25, all point to the Anytone 779 as the original
