[MRCG] Searching for an O-39()/TRA-7 Frequency Shift Exciter

[Robert Kilian]

Hi All -

I've been in search of an O-39()/TRA-7 frequency shift exciter for the 
last year or so (to add proper RTTY capabilities to my someday-to-be 
AN/GRC-26 station, the build of which is currently in its infancy), and 
my casual efforts have turned up exactly 0 results.  Lately I've posted 
a WTB on QRZ.com, checked around with a few vendors (Fair Radio, SSN, 
etc) with no luck.

Thought perhaps the Clatternet group here might have some leads on where 
I can find one of these units.

Thanks in advance for any leads anyone might have on where I might find 
(or look for) one of these.
