[Milsurplus] Re: Nems-Clarke Receiver

Brooke,
Remember that some of the signals surveilled were telemetry. And in
that era (1960's) you could buy a bunch of them instead of one DC to
Daylight "Surveillance" or "Intercept" receiver. Later (1970's) all
band systems (like ACL or WJ) were more common.

I recognize the black plastic housing as a squirrel-cage blower. I've
seen that shape before, but I can't remember a specific make or model. 

No idea on RCA patents.

Hi Glenn:

Nems Clarke (relation?) 1302A
<SNIP>

I thought this was used more for telemetry than for "Surveillance".
Any ideas on what RCA patents it uses?

Have Fun,
