[Premium-Rx] Racal RA6840 manual.

[Tom B]

Hi Greg,

By some miracle I found my copy of the RA6830/JD manual. Unfortunately, 
each schematic has a tiny bit of the right side cut off.  I guess it's 
better than nothing.

I am not sure you need the A8, A7 is the demodulator/BFO.  A8 is a 
"special demodulator" which has some extra outputs.

I have some parts around here.  Finding them might be a problem but let 
me know what you need.

I would recommend you contact Gary Wingerd.  He is ex-Racal and has lots 
of stuff.

You should also sign up for the Racal Radios list on groups.io 
(RacalRadio at groups.io).
