Original Item: Only One Set of Two available. This is an original set of two Vietnam War Era U.S. Signal Corps RT-196/PRC-6 Radio Receiver Transmitter Walkie Talkies. This equipment has not been tested by IMA but we were told that the complete example is functional. However, we will not guarantee functionality. These sets look to have been used post war, and both have been painted U.S. Navy , with USN stenciled on the side.

One unit was made by RAYTHEON MANUFACTURING CO., and has serial number 48570 on the label. The contract information indicates it is from a U.S. Army contract in the 50s, but was doubtless used into the Vietnam war era. It is unfortunately missing the flexible antenna, but those can be sourced relatively easily. The sling on the back is also not completely attached, and looks to have an extra set of loops. Internally it looks to be complete, with all vacuum tubes present as well as the RF shield.

The second unit no longer has the data plate, and is also missing the antenna as well as the carry strap. It still has the internals, however it looks like all of the standard size and subminiature vacuum tubes have been removed, so it is definitely not functional without these missing parts. It is also missing the shielding and battery compartment diagram, so it was most likely used as a source of parts.

A nice honest set of surplus "Walkie-Talkies", ready to add to your collection!

The AN/PRC-6 is a walkie-talkie used by the U.S. military in the late Korean War era through the Vietnam War. Raytheon developed the RT-196/PRC-6 following World War II as a replacement for the SCR-536 "handy-talkie". The AN/PRC-6 operates using wide-band FM on a single crystal controlled frequency in the 47 to 55.4 MHz low band VHF band. Rated power output is about 250 mW. The range is about one mile (1.5 km), but much less in jungle.

The AN/PRC-6 circuit uses 13 vacuum tubes for the receiver and transmitter combined, all but one subminiature. The unit may be changed to a different frequency in the field by replacing the crystal and adjusting tuned circuits, using tuning indicator ID-292/PRC-6. The tuning chart inside the case is not accurate enough to properly align the unit. The AN/PRC-6 uses a 24 in (61 cm) whip antenna, with a BNC connector for an external direction finding antenna. There is an optional handset H-33*/PT that can be connected to the AN/PRC-6 by a 5 ft (1.5 m) cable. The RT-196 can be carried over the shoulder using a provided web sling.

The US Marine Corps made limited use of the AN/PRC-6 as late as 1972.

The AN/PRC 6 was also manufactured under license in France ("TR-PP-8") and Germany (6 channel version or PRC6-6). Israel too manufactured single channel equipment. Modernization of the AN/PRC6 resulted in various solid state crystal controlled and synthesized radios, usually with higher output ratings. For example, Greek valved sets were refurbished in the mid-1980s and converted into single channel solid state one watt units housed inside the original casing. These updated solid state versions were given various designations such as PRC-6T (for "Transistor"), PRC - 6T/180 (180 channel synthesized unit) and PRC - 6GY.

The frequency range of the PRC-6 covers the 6 meter amateur radio band (50-54 MHz in the US and Canada, 50-52 MHz in the United Kingdom), and the many versions of these sets are relatively available and cheap (around £30-40 in the UK) in comparison to other vintage military radios. As a result, many examples have been put on the air, although practical operation is hampered by the necessity of building new, custom power supplies (the original dry batteries, which supplied +1.5, +4.5, +45 and +90 volt outputs, being unobtainable or display pieces only) and the limited output power and range. In addition, a separate crystal and laborious retuning is required every time a frequency change takes place. For this reason in the US 51 MHz is used as a net frequency at many radio events, necessitating only the one crystal.
