[R-390] R-1247 Nasa Receiver info

I recall back in the early '60s listening to Gemini capsule communications  
on HF SSB.  I assume that NASA was linking comms back from one of their  
remote sites like the Azores or Australia.  Maybe they didn't want to  
maintain the staff that the military used to supervise the operation of RTTY and  
SSB reception, hence a setup which would be frequency stable to a few  cycles.
