Guest post: A look at the Clansman PRC-3512 Low Band VHF Radio...by EI5DD

Regular visitors to the blog will know that I try to promote more interest in the low-VHF part of the spectrum by having a dedicated page related to the new 40 MHz / 8 metre band. If I come across anything of interest that might be related to the band then I post it here on the blog and link to it from the 40 MHz page. 

The Clansman is an ex-British army radio that can operate on FM on the low VHF spectrum from 30 to 76 MHz. As such, it is one of the few radios available on the second hand market that can operate at 40 MHz, 50 MHz, 60 MHz or 70 MHz.

The Clansman PRC-3512 is an intra-platoon level backpack VHF FM transceiver. The PRC 351 has 4 watt RF power output, and operates in the 30–75.975 MHz range with a possible 1840 channels spaced 25 kHz apart.

This radio is also capable of being mounted on a vehicle in conjunction with the TUAAM (Tuning Unit Automatic Antenna Matching). The PRC 352 is identical, with the addition of a 20 watt RF amplifier and can be used as a ground station also.

The Clansman RT-351 / VRC-351 Back-Pack 4 Watt portable VHF (FM) Radio was made by RACAL BCC Ltd. in England. The PRC-351 was designed to provide command communications at battalion and company level for dismounted troops. It was also used in vehicles by mounted troops. The PRC-351 replaced the older A41 and A42 British VHF radios.

The frequency Range 30 to 76.000 MHz in 25 Khz steps giving a total of 1841 programmable channels. The desired frequency is set by four knobs on the side of the radio which can be operated even while the operator is wearing Arctic mittens, or in the dark by counting clicks from the end-stops.
