Great info Frank and now it brings back some memories when K2ZSQ and I
visited Ed at the Mt. Tabor location around 1959/60 for the The VHF
Amateur Magazine. As Ed was giving us a walking tour of the manufacturing
facilities, I remember him pointing out in the lab area where they were
testing a number of pieces of equipment, a rack of equipment which he
called "very unique" but not in real production, and vaguely remember
something with the name Climaster on it. Since we were there to find out
more info on the current products he brought to market, I don't recall
any further discussion about the equipment in the lab area, but it may
have slipped in one ear and out the other. Back in the 90's, Ed sent me a
bunch of Clegg documents he still had, but none of that equipment info
was in there. I got to go check the old VHF Amateur issues I still have.
I pretty sure there were some station photos of KH6UK and K2RRG in some
of those issues. It's also interesting that Ed had the tube crystiplexer
design in the 50's, and in the 70's, it rolled over to an all solid state
design for his 2 meter FM rigs.
Whatever happended to the one you owned?
Pete, WA2CWA
