AN-PRD 2 radio detection finder pictures

Post by Johnsamschulz » Tue Apr 13, 2021 10:54 am

The museum at Fort Huachuca Arizona is planning to have a static display of the AN-PRD 2 radio detection finder mounted on a 1965 M151A1. Does anyone have any pictures or Army TMs showing how the AN-PRD 2 radio detection finder was mounted on the jeeps? Any help would be greatly appreciated.

The basic equipment consists of a loop antenna, a superheterodyne-type receiver, and power supply unit. The equipment covers a frequency range of 100k kc (kilocycles) to 30 mc (megacycles) in seven overlapping bands. The set is capable of receiving cw (coninuous wave), icw (interrupted continuous wave), and a-m (amplitude modulated) signals troughout the frequency range, and of receiving f-m (frequency modulated) signals in the range of 12.5 to 30 mc. The complete equipment consists of Antenna AS-536/PRD-1, Antenna AT-301/PRD-1, Radio Receiver R-395/PRD-1, Dynamotor Power Supply DY-79/PRD-1, Battery Box CY-947/PRD-1, Direction Finder Tripod MT-870/PRD-1 and a number of additional components.

Interesting, have AN/PRD-1 mounted on my M151A1 like we had in Vietnam. Have more than one PRD-1. The TM 11-677 dated Oct 55 shows PRD-1 mounted on a M38 jeep. In Vietnam we mounted them different with the VRC series radio systems. I did keep in touch with the museum at Ft.Huachuca , Arizona a few years back. Can't remember the contact person. We used PRD-1's in Vietnam. Was with Army Security Agency. Cover name Radio Research Company. If you still need any info let me know. I have photos of mounted PRD-1 and how they were mounted. Look up National Army Security Agency Association Facebook page. Shows PRD-1's.
