[GreenKeys] OT - Hal made receivers?

[COURYHOUSE at aol.com]

>From the  SMECC Archives  -  Bill Henry  tells  us  - 
"The  HFCS-1000 is a simulator of the RACAL RA-2174 receiver. The front 
panel  duplicates the RACAL but the HAL unit is not a receiver itself. We built 
many of  them for DOD to train intercept operators. It simulates the 
presence of over 1  million CW and RTTY signals over the tuning range of the 
"receiver". A room full  of HFCS's are hooked via LAN to an instructor's station 
who can download  "signals" on various frequencies and transmit typical text 
to each student. The  test is of course to find the "target" among all of 
the background signals,  noise, QRM, etc. and correctly copy the text. It was 
a fun project for  us."

That  would explain a lack of antenna connector on that  unit!

If I remember correctly, the Hal HFC-1000s were not  receivers at all, but 
rather were training aids in the use of the Racal  RA6790GM receiver in 
various intercept operations.  Several HFC-1000s,  essentially an RA6790 GM 
simulator designed to look and operate like the  actual Racal receiver, were 
connected to a central training console operated  by instructors who sent 
simulated signals to the student "workstations", and  observed the student's 
actions as they operated the simulated  receivers.

This is the  first one I've ever heard of.
Does anyone have any first hand  experience with them?
