That allows it to be moved to another band by replacing the board with one for another band.
At some point I wonder if it would be possible to build QRP to moderate power TX stages at low enough cost, that rather than using relays or other filter switching methods for a multi band transceiver, you could just have a separate final RF power transistor and filter for each band. Just turn on the output section for the band you are interested in. Hopefully the filter sections could be designed so they could just be common connected together for the antenna connection.
