Hi:

Well, I hate to be the one, but I am affraid
your radio is in the low range. That means
it will work well in the 403-435 Mhz range, but will NOT work in the 459-460 Mhz range.

You can fool the Firmware into beliving its a 450-470 Mhz radio, but good luck with the
Componets that would need changing to make
it work in the 450-470 business Band.

There are a couple of VCO Coils you can adjust to make it work up to around 445 Mhz, but that been the limits I have played with.

Hi

Whats the way to programm over 433 Mhz ?
Its possible more then 4 channels ?
Then I can use this TRX for german HAM Band from 430 to 440 MHZ
