Hi Peter,
-
Hope you get to feeling better... and thanks for the note.
Dave chimes in with the mod, but I've yet to locate a
copy. Anyone on amps able to provide me with a
photo copy or scanned image..? I'll post it on the sonic
server for everyone if permission is given to do it.

cheers

skipp,
back in the late 80's or early 90's, there was an article in CQ about
ganging
these switches. Sorry, can't be more precise, some index searching is
called
for.

Peter G3RZP
CQ Magazine, July 1991, page 32 provides mod instructions to convert the
switches sold by FairRadio into ganged switches. I've modified several
for
antenna matching units using this article and it is fairly easy to do.
