I'd just like to know what the band modules are - I'm guessing they'd be an off the shelf item - say Tuna Topper or Lil Squall board. I guess Rex will be able to answer.
I've noted that LPF component values are helpfully added on the PCBS silkscreen.

Gangue,
If your intention was to have a BAND SPECIFIC Beaconator][ or Tuna Tin 2 transmitter, then you could use the filter values provided in the silk screen table on the top of the Beaconator][ pcb to hard wire the Beaconator][ to the band desired as there are fixed component pads for a hard wired filter in parallel with the connector for a band module. Build the low pass filter to your needs or budget. Another example of providing extra FUN value in a simple tuna can kit from QRPme.
