Gordon,
That looks ideal, many will be reluctant to deal with removing the relays from the board.
If we give up on the 15m,12m,10m bands due to the (45mhz-FOp) spur,
that means all we need is two relays on each side of the three remaining LPF's.
The Fujitsu surface mount relays I mentioned before are around $3 each,
and while not exactly on 0.1" centers they will mount nicely to vectorboard with pads on 0.1" centers.

Hi Jerry --- I don't think you were addressing ME, but I just proposed about the same thing on a slightly larger board.??

From my photographs and examination of the board, it looks pretty easy to make the required cuts and connections without removing the existing relays.? ?You can see the cuts required on the photo below.? ?I think they could easily be done with an exacto
knife, or with a 1/16-1/8" drill, or with an endmill in a drill.? ?

If you make multiple wide?cuts on the long traces, their series gap capacitances should be sufficiently small to knock down any bleed-through quite well (I think).? ?Grounding them might even knock it down further.? ?Won't know until this is constructed
and tested.? ?

And of course, different people may reach completely different conclusions on what is the best solutions, depending on what they feel is the best work/benefit ratio!
