Hello Jerry:
That receiver was on the TMC drawing board when I left the TMC
engineering department for other opportunities.
I have been trying to remember the name of the project engineer on this
receiver project, now it came to me, Julius Anger. What a character! He
was a fun guy to work with. He worked for Hammerlund designing the
planetary drive system for the SP-600 receiver, then came to TMC. Ollie
Pose and Bill Prichard where still there I think.
Do these names bring back memories?
Ciao, Tony Faiola, K3WX (ex W2GBS)
