Fw: [Premium-Rx] How do you use it?

[refmon]

 Hi,

 Just catching up on some back mssgs and I saw mention of the 10Hz IF
 bandwidth.  Does anyone other than that other guy (you know who you are)
 have a WJ 8940B?  It's black in a blue case and weighs in around 500lbs...
 if you have one, you probably know it, or at least your wife/sig-other 
does.
 This receiver, which oddly escapes any mention in any premium-rx - related
 stuff, is a fabulous example of engineering when engineers were real
 men...for those of you not already alienated, further features include:

 a DCU (digi ctl unit) with an LSI-11 mini-computer based processor driving 
a
 plasma display

 zero-ish Hz to 18GHz coverage capability

 tempest approved

 IF bandwidths from 10 Hz through 500MHz (working from memory here)

 "Transistorized", and they mean it

 only about 50 made (at least 6 of which are owned by a secret consortium of
 listeners)

 drives external spectrum displays, plotters, and GPIB bus stuff

 takes up to 6 sensors (antennas)

 receives SSB, CW, AM and mates directly with external demods and tuners

 and a bunch of other cool stuff

 regards

 John Collins.....I mean.....agent X33
