The good news is there are enough control signals to select either 2 or 4 band filters.
Where to put them and also add gain to make up for insertion loss are issues.
If only one band its easy.? The filter and detect that no other than 30mhz low pass is selected.
That takes a transistor and a relay.? And a band pass filter for 10 or 15M, pick one.
Still needs more gain to get power out on 10M then.? A MMIC with 10-12db gain good
for +5 dbm or more would do fine.
