[Milsurplus] Mercury Comms

[Jim Karlow]

David -

Yes - it is funny what one hold on to and what one throws away. I was never
able to get documentation on these radios, but I know it exists. I was
hoping that with the information I provided, someone could turn up the
documents. I once contacted Collins Radio regarding the 618V-1 and they
indicated that they no longer maintained documentation on this radio. They
did indicate, however, that they were required to provide full documentation
to be included as part of the permanent record of the Project Mercury
program. In some dusty file cabinet somewhere this stuff does exist. I once
also had the Mercury tracking station manual from the Kano, Nigeria station.
It used a crystal controlled VHF convertor and an R-390 as the IF. AMPEX
FR-100 Telemetry recorders were used. Master Timing was done with a Vitro
Timing Code Generator for establishing estimated AOS and LOS. For Gemini the
converters and R390s were replaced by Vitro-Nems-Clarke Telemetry receivers.

All the best,

Thank you very much for sharing the photos.
