[Premium-Rx] Photos inside listening posts

[Terry O']

I've been researching the history of surveillance radios for many years 
and found that photos from inside listening posts are very rare.  If any 
readers have copies or have seen them on the web, could you please share 
the information with me?  My primary interest is before the Berlin Wall 
was torn down and SIGINT/COMINT sites, but ELINT and TELINT sites are 
almost as interesting.

Best,
Terry O'
