[Premium-Rx] Wanted: R&S EK07 Connector - European Audio Connector?

[paul at kluwe.com]

First, Merry Christmas to all on the premium-rx list; and best wishes  
for a high intercept point 2009 with little QRN and QRM.

I have a Rohde & Schwarz EK07 with the NZ/10 sideband adaptor.  I need  
to make up some interconnect cables, and the radios require a  
connector that is 3-pin plug with a screw collar.  It appears to be a  
European-style audio connector somewhat similar to the XLR variety.  I  
am looking for any information on this plug: part number,  
manufacturer, source, or anything!

Thank you very much!

Best,

-Paul
