[TMC] Rarely seen TMC receiver -- DDRR-10 variant

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)
