Just to make sure we are all on the same page (as is said).
We already have 6 "bandstop positions" in the VFO, that control 6 processor pins, which control 6 relays and switch 6 Low Pass Filters if you add the relay board kit http://qrp-labs.com/ultimatelpf - all of that already exists.
Are you saying that you want 5 MORE so that you can control 11 relays? And if so, with what spare extra 5 I/O lines? Or you want a way to multiplex two relay boards?
