[NLRS] Systron 5000a modules

[mike]

Hi all, had a good time (short as it was) on the contest.  I've never 
operated on 6M before 2 weeks ago and never seen an opening.  All I can 
say is wow, I had to listen to that DM station for 10 minutes before I 
figured out what was happening.  Lots of fun.

Any way, I am wondering if anyone knows of any source of modules <1 GHz 
for a Systron Donner 5000a sweeper????  (besides ebay, haven't seen any 
in the last 2 months)

Thanks
Mike
