Hi Eugene

Thanks for the pix/words describing the beast.  It sure did raise a lot of 
interest! The "video" outputs are not video in the now accepted sense (ie 
video rastered into pictures as TV) I recall that the Audio band went up to 
circa 20 kHz and everything baseband higher than that was "video".  The 
"video" output went either to selective AM (or FM/PM) receivers that 
allowed the FDM (Frequency Division Multiplexing) to be resolved (WJ made a 
number of receivers for this purpose) or in the case of EMC/Tempest 
Recievers the video output is connected to an oscilloscope for signal 
analysis (as it is for Electronic Warfare/Counter-measures) or automated 
signal recognition equipment.

WJ produced a number of Tech Notes describing the techniques which are 
either on the Premium Rx website or at 
http://www.wj.com/technotes/index.asp.  This is a very interesting read if 
you have not viewed these before.  Taught me a lot these did about the 
history of the development of the radios and what they were used for - a 
bit of imagination helps a lot.

Best regards
