[Elecraft] KBPF3 General Coverage Receiver -- Main or Subreceiver

[Bruce Beford]

If you only have 1 bpf module, I'd probably install it in the main, I guess.
I added a second one for my sub RX later. Opinions will probably run on both
sides, but I'd like to hear the arguments one way or the other myself. (not
that it really matters to me- as I said, I have it in both positions.
