Hi Paul,

The driver for the Anytone AT-788UV, Retevis RT95, CRT Micron UV,
Midland DBR2500, etc. is currently a work in progress. It currently
only directly supports entering frequencies within the USA 2 meter and
70 centimeter ham bands (because the radios used to develop the
initial driver were factory set to only cover those frequencies).
There aren't any settings implemented yet, as well. It is being worked

My Retevis came from the factory set to cover only "ham" frequencies.
I have switched it to cover 136-174 MHz and 400-490 MHz. For testing I
also programmed the local NOAA WX Radio frequency. I must say, that is
about the best audio I have ever heard coming from the local NOAA WX
Radio transmitter.
