HI Tim,

I have 2 FRK's here both use a connector made by Positronic, it's a GNCT 20.
See http://www.connectpositronic.com/downloads/pdf/C009RevC_StdDenRec.pdf

The Positromic site says (for Australia):

Australia (Commercial & Industrial & selected Military Accounts)
Walcom Pty. Ltd

Ourimbah, NSW 2258 Australia

I bought one complete connector assembly on Ebay a while ago for like $10.



Regards,

Hi all,
Now that I have my FRK working I have to find a connection for it.  I 
believe it is a winchester 20p and I have not been able to find one in 
Australia yet.  Is it worth while looking or should I just replace it 
with something else or even solder leads to it!
As an aside, what resolution counter is needed to calibrate the FRK?  Hp 
5328? HP 5370?

Thanks
Tim
