mmwave bands tuning now OK

Neil Smith G4DBN

Thanks to Vianney for fixing the advanced tuning panel so it now works on the microwave and mmwave bands.  Nice to be able to see the actual frequency on the display.  Now I just need enough bandwidth to monitor the whole of the 2mm band. That would need 7 GHz.  Makes even an S3 at 24 MHz look a bit restrictive!
