Building the ParaSet

I first heard of a 'Paraset' when I saw a message on the QRP-L reflector announcing an upcoming 'June 6th Paraset D-Day' activity. A search for more information soon revealed that the Paraset was a small vacuum-tube transmitter-receiver unit built during WWII in the UK at the Whaddon Hall headquarters of the Secret Intelligence Service Communications Unit.
