[Icom] Found a problem.

Hi Bill,
Roger that 100%. The old B+W switches are very nice, but the isolation is
definitely an issue. I use a couple of Alpha Delta 4-port switches in
cascade, it wastes one port but provides 7 isolated,
grounded-when-not-in-use connections. At HF the extra loss of the 2 swithces
is negligible.
BTW, I have always believed that MFJ was one of the "true ham suppliers" in
the "true spirit of hams", i.e. that you have to tinker with their products
to get them just right (tongue in cheek).
Seriously now, I want to tell you that I took your entire "761 Saga" in, and
thoroughly enjoyed reading it. Not many people would expose their foibles
and follies for all to see. Your determination to get the rig squared away
was very impressive, and your posts have, I am sure, motivated more than a
few people to try harder. Thanks for the great contributions.
