Description

The Retevis RB75 is a GMRS HT. It seems to have come out recently. I bought a 5 pack and a programming cable and have started to play with them. They are not yet supported by CHIRP, and the included software is terrible.

I've sniffed the magic string from the included software, ".KVOGRAM" (with the first char as 0x02), but haven't determined the memory layout yet.

Attached is a factory default dat file read from the included program and an html page with the serial communication dump between the radio and the included program doing a read and two writes to the radio.

I have explored the existing retevis drivers, I believe this radio is likely close to an existing model.
I may try to code this myself as a weekend project, but if these details make it obvious to someone I'd love to see that.
