While I was out running around today ...I stopped by the Historical Electronic Museum .. They had asked me a while back if I would lend them one of my old receivers ( SX-73 ) for a Hallicrafter / Heathkit display ....  They did a great job on the display ..... They also had a very early ham radio wireless display .....  Here are some photos  ... use the photos all you want ....... the receiver in the center cabinet without chassis covers ( because it was made to be rack mounted only ) is my SX-73 ....It was a great Hallicrafter 20 tube military receiver and was also used by some ham radio operators  ...
