I have tried this on my radio and it works just great . TX is from 140
Mhz to 170 Mhz and 400 Mhz to 470 Mhz with no degradation in the
receiver or transmitter . I also placed the radio on a service monitor
and specs were the same as manufacturers specs. ( except the
transmitter He He He ) Be careful and have fun, Any questions about
this mod please feel free to E~Mail me anytime.
