Arv,
If using an external filter box and the uBITX internal filters remain in place,?
it seems that the external filters would only need to be activated in transmit?
mode.? That could save some power when in receive mode.??
As is they are wired to only be active on TX.? The only get power when
K1 supplies "TX" (K1 pin 1) voltage to the transmit hardware and that
includes KT1-3 and K3.
With that said .... one can disable all but K3 and with three etch cuts and
jumper TX RF direct to K3 pin16 around the filters completely.? It should
save about 120-150 mA.
