[GreenKeys] Looking for Information on Racal/ Intertec demodulator

Hi all

I have bought a FSK demodulator unit which was advertised as a Racal 
RA17 accessory unit. However, it appears to probably have been 
manufactured for Racal by a UK company called Intertec. It is a GD396, 
and is settable to a variable shift, 30 -1500. It has an input for 
100Khz IF and two other connectors on the rear. I assume one is for a 
Remote (control?) unit and the other to be for Teleprinter but thats all 
a guess.

It matches RACAL in colour scheme, is 1 U high  and there is one shown 
at the wonderful site of PA8PDP:

http://www.pdp-11.nl/racal/update-status.html

It is the item right at the top of the 2nd bay along from the right of 
the big picture.

A Racal AK30 unit came with it, which appears to be simply an IF 
distribution unit.

I have so far been unable to trace any information on this unit. One web 
site in the UK lists a manual but they seem to be out of business. If it 
were not for the picture at PA8PDP I might think it was all in my 
imagination!

Can anyone help, preferably with at least connection information, if not 
a manual?

Martin
