Dan, I’m not sure how you find these things, but wow! I know you had a lot of fun unboxing this NIB WJ 8711A! How amazing it is to turn on a radio like this that’s been in the original box for two decades! I hope you have a lot of fun with it on the air. Thank you for sharing!
Many thanks to SWLing Post contributor, Nick Booras, who shares the following video and notes:
As a SW listener and radio collector I have enjoyed many hours perusing your blog and reviews. I recently started posting YouTube videos of some of my collection and thought you and your viewers might find them interesting. Please take a look at my youtube channel – dieselten01
My most recent vid included some pretty cool older surveillance type receivers.
The Watkins-Johnson HF-1000 (and NSA version, WJ-8711) are mentioned in this article
On January 11, 2012 the National Security Agency (NSA) released a pre-1995 article entitled “Receiver Dynamics” from its classified internal magazine, Cryptologic Quarterly. It contains an excellent, well-written explanation of the specifications of shortwave receivers used by some of NSA’s K4 divisions.
