Folks, I have seen mentioned a mod for the IC740 and other similar rigs,
that provides a "wetting" current flow through the relay contacts to
ensure the contacts remain clean and serviceable. I cannot find this mod
in the usual places. Would someone please direct me to the appropriate
site. I have just obtained a fully loaded IC 740 and are gob-smacked at
the receive performance....it takes a very expensive late mod rig to
come even close.....I reckon it proves the point that tight "ham bands
only" filtering with the consequent need for only a low output PLL makes
for a very quiet and effective receiver.
