Hi Alison!
Yes, I saw those photos and thank you for sending them again! They will make it very easy to see exactly which traces need to be cut. ? ?I took a quick gander at them, and I think I can see the ones to cut but I will need to download the pictures and Mark
on them and send them back for others to comment. ?
Luckily the ones that need to be cut generally go a long way across the board. ?(they get replaced by wires going off the board to new relays, ending the feed around!). ?The others that go from newly unused relay section to newly unused relay section and
are no longer needed,??can simply be shorted to ground with a jumper underneath the board.
Sure wish I had a spectrum analyzer. ? I can make some basic measurements with an S meter. ? Will have to construct a voltage divider on my Heathkit Cantana.?
It will take a week or so to get the boards from China. And digikey will have parts to me probably next week early. ? Then we¡¯ll see if I can carve out an evening to build this. ? If my S meter reading suggest it did some good I may ?ship it to one of
you folks for real readings.... if there is any doubt
Wow, you folks have taught me so much.

Gordon,
The real problem and it came up elsewhere is getting to the traces so you can still use the relay.
We went down the rat hole of desoldering the relays as unfortunately most of the conductors
you want to get at are on that side of the board.
I did that and here is what you see...
