Only One Available. This is a good service worn Canadian RT-5010 \/ PRC-510 manpack receiver-transmitter manufactured by Addison Industries in 1955. The radio retains its original data plate and is accompanied by a U.S. manufactured ST-120A\/PR carrying harness, two antennas, and a later U.S. H-33F\/PT handset. The accessories are suitable for display but are not all compatible with the Canadian radio.\u003c\/p\u003e\n\u003cp\u003eThis equipment has not been tested by IMA, and no guarantee is made regarding its operation. The radio and accessories are offered strictly as historic display and collection pieces.\u003c\/p\u003e\n\u003cp\u003eThe RT-5010 \/ PRC-510 was a Canadian development of the American AN\/PRC-10 family of portable VHF tactical radios. It covered a frequency range of approximately 38 Mc\/s to 54.9 Mc\/s. The Canadian version can be distinguished externally by its more finely graduated tuning dial, altered antenna connector block, and an additional audio connector on the right side of the front panel.\u003c\/p\u003e\n\u003cp\u003eInternally, the design was related to the PRC-10A but incorporated several Canadian modifications, including a different discriminator transformer, an additional pulse-sweep generator, and a single calibration oscillator.\u003c\/p\u003e\n\u003cp\u003eThe radio retains the original data plate:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003e5820-21-100-1600\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eRECEIVER-TRANSMITTER\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eRT-5010 \/ PRC-510\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eSER. 1594 1955\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eADDISON INDUSTRIES CANADA\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe harness is also stamped on the back with maker information:\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cb\u003eCARRYING HARNESS\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eST-120 A\/PR\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eKEITH \u0026amp; KEITH INC.\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eDA-30-069-AMC-01991 (E)\u003c\/b\u003e\u003cbr\u003e\u003cb\u003eUS\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe harness is a period U.S. military pattern associated with the PRC family of manpack radios. Although suitable for display with this set, its loose fit and U.S. markings indicate that it was not necessarily original to this Canadian receiver-transmitter. The shoulder straps are not connected to anything so the set will not work as a backpack. The harness retains both the long collapsible and bendable antennas, and the long antenna still screws into the mount on the top of the radio. The flexible antenna was not able to screw in.\u003c\/p\u003e\n\u003cp\u003eAlso in the harness is an original U.S. handset, but as it is U.S. made, it will not attach to the radio and is only included for display.

Like the related PRC-10, it was a substantial vacuum-tube radio designed to be carried on the operator’s back or installed in a vehicle.\u003c\/p\u003e\n\u003cp\u003eThe clear Addison Industries data plate, 1955 date, serial number 1594, U.S. ST-120A\/PR harness, retained antennas, and later H-33F\/PT handset form a visually complete Cold War radio display. The untested condition, loose harness, incompatible flexible antenna, and nonconnecting 1982 handset are important limitations, but the Canadian receiver-transmitter itself remains a well identified example of mid-1950s military communications equipment.\u003c\/p\u003e","brand":"Original Items","offers":[{"title":"Default Title","offer_id":45488838213701,"sku":"ONSV26WSV036","price":550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1524\/1342\/files\/ONSV26WSV036__01.jpg?v=1785957951","url":"https:\/\/www.ima-usa.com\/products\/original-canadian-vietnam-war-era-receiver-transmitter-rt-5010-prc-510-radio-by-addison-industries-dated-1955","provider":"International Military Antiques","version":"1.0","type":"link"}
