The Technical Materiel Corporation produced scarcely more than 100 examples of the GPR-92 receiver. The 18-tube set covered 0.54–32 MHz in five bands. The receiver shown here has amateur band calibration on the band-spread dial. Other versions were made with commercial or broadcast-band spread; $920.00, 1963. (1)
