New on the forum and I have read through all the posts in the thread "Aeroflex (IFR) Questions".
I recently got hold of a nice IFR / Aeroflex and formerly Marconi 2945A comm test set.
It really works fine and for me being a pure hobbyist in electronics and radio comms this test set is a dream for me. I can now reduce some of my bigger and more heavy instruments from my home lab.
I have read through the user and service manual and I can't find any information if the option 8, SSB demodulator is possible to retrofit.
I read in @Wowbagger's post http://batboard.batlabs.com/viewtopic.php?f=42&t=80947&p=469516&hilit=2945a#p469518 in the Aeroflex (IFR) Questions thread that
"Software upgrade and purchasing of options and manuals should be handled though Service, just like anything else - I know they can handle that line."
The above post was made in Nov 2013 by @Wowbagger and I see now that Aeroflex is a divison of Cobham nowadays. I have contacted Cobham several times asking to buy the option 8 but I have not yet got any reply back. It was 2-3 months ago now and still no reply.
@Wowbagger: Do you have any contact details for the specific service department that MIGHT be able to help me out purchasing the option 8 SSB demodulator for 2945A?
