The Clansman PRC-319 was a rugged zed man pack radio build by MEL (Philips) in the late
1980s. It was used for Special Operations by the UK, the US, Australia and New Zealand. Only
350 units were built for use by the British Armed Forces. Secure communication was possible by
using an Electronic Message Unit (EMU) or a Digital Message Handling Device (DMHD).
The image on the right shows a PRC-319 unit outside
its canvas back pack, with its typical two keypads.
The unit on the left is the EMU and the rightmost
keypad is used to control the transceiver.
The PRC-319 operates from 1.5 to 40 MHz in USB,
CW and Data mode. Transmitter and receiver
frequency can be set independently, allowing split-
frequency (half-duplex) operation. Maximum power
output is selectable between 5W and 50W. The
rugged zed case is water tight up to 6 feet. The radio
weighs-in at around twenty-five pounds with
maximum battery capacity.
The set is specified for a range of 20 km when using the whip antenna or 1000 km when using a
wire antenna. An automatic antenna tuner (TURF) allows most types of antennas to be used.
For frequencies below 4 MHz and additional antenna unit (TURF Extender) is required.
UK/PRC 319 - Special Forces and STA Patrol man-portable, patrol level radio HF / VHF, Half-
duplex transceiver, which was built in the United Kingdom by MEL. Features include key-pad
entry of frequency, mode and data with digital LCD display; 10 pairs of pre-programmable
channels; half-duplex operation with the option of transmitting and receiving on different
channels; the option of using a removable pocket sized electronic message unit (EMU) to
transmit and receive short data communications; fully automatic antenna tuner which can be
remoted up to 50m from the set using standard co-ax cable; Self test facility. power output is
50 watts PEP on high power setting with an adjustable low power of 2-5 watts. Frequency range
is 1.5-40 MHz allowing short range VHF communications overlap with the other clansman series
radios on the higher frequencies.
The PRC-319 was built by MEL (Mullard
Electronics Ltd) for the UK Ministry of
Defense (MOD) around 1988. MEL was a
Philips subsidiary and was later sold to
Thales. Support for MEL equipment has
PRC-319 Manpack Radio description:
This radio was primarily used by special
operations units in Britain, Australia, and
New Zealand. It was built my M.E.L. in the
U.K. Included is an Electronic Message Unit,
which is a small keyboard that allows
transmission of data.
It is an all solid state, 1.5 MHz to 40 MHz,
Transceiver w/automatic antenna tuner.
Power levels are selectable at 5W or 50W;
Modes are CW or SSB (USB only - USB
voice mode uses 'The Third Method' to
generate single sideband) or Data.
Stability is better than +/- 0.5 ppm, -31C
to +55C and is NTIA Compliant.
The radio is sealed and will withstand
immersion in 6 feet of water.
Pack weight is 20 pounds with small NiCad 1.2 AH or with a LiIon pack attached, It is 25 pounds
with 4 AH NiCad battery pack. It has a 10 channel receive and 10 channel transmit (Fixed
frequency operation only) memory. It has no frequency dial or up/down buttons to 'tune'
around. You may use the specific frequencies dedicated by the HFpack group. They are
28327.5, 21437.5, *18157.5, *14342.5, 7296.0, 5371.5, and 3996.0 kHz. Go to
http:HFPack.com for more info. (*Main Channels).
It uses a direct conversion receiver, (which has no local oscillator to give away your location or
operational frequency). The designers thought that was necessary for low probability of
detection and low probability of intercept.
The Antenna Tuner (BA-1303), which clips on top of the radio, tunes within 250 milliseconds, (It
is like the LDG Z-11 automatic tuner) and uses latching relays for zero power consumption after
it is tuned. It has a Tuner Extender (BA-1305) for using a whip below 4 MHz. The satchel
(Backpack) has a slot to carry an 8 foot segmented collapsible whip.
