[Icom] IC-756pro2

[George, W5YR]

Blair, they use both for different applications. Some circuits are
relay-switched and other use PIN diode switching.

Relays or diodes switching filters and such circuits usually has more to do
with IMD effects than QSK "transparency."

Not a very good answer, but not sure what your question is after . . .
