• Notes
• The models PAR-80 and PAR-80A differ only in very details like missing resistor 16. Russet leatherette and plastic 3-way portable. 5 Tubes and rectifier. We found the first reference for this type of portable radio in "Radio & Television Retailing", August 1946 for the Bendix model 686A for AC-DC or battery, already with three-gang tuning condenser, in September 1946 for Bendix model 687A and in May 1947 it was called Bendix Airmarine Portable, model PAR-80 and PAR-80A with additional socket for Head Phones and an Antenna Jack above the 4 knobs. The schematic shows the 6 tubes which we assume were already also in the first models. The band coverage of the PAR-80 is 195 to 410 kc for airport control oowers, civil airway stations, radio range, marine beacons, etc.); 540 to 1620 kc for standard broadcast; and 2000 to 5800 kc for marine communications. Two enclosed loop antennas for reception and direction finding plus external antenna connector. 150-hour battery pack. The leatherette is called "Tolex" textileather, designed by Robert Bingman.
