The British Army Clansman UK/RT321 HF system has been designed
and developed for mobile military use in all types of armoured
and logistic vehicle. It is primarily designed as an HF
vehicle station for mobile ground-wave operation, but can
also be used as a ground station, or for sky-wave operation
over long distance. Digital frequency selection in 100 Hz steps over the 1.5
to 30 MHz band is provided. All frequencies are synthesised
from one reference oscillator, with a warm-up time of less
than 90 seconds, and the receiver/transmitter frequency
is selected by decade switches. Two stations can be operated
independently in one vehicle with only 10 per cent frequency
separation and 1.8 m antenna separation. This requires 150
dB suppression of unwanted emissions and receiver responses.
The equipment operates from a vehicle power supply which
can have a wide variation in nominal voltage and suffer
from ripple, surge and transient variations. It has a power
consumption of 30 W on receive and 140 W on transmit to
provide 40 W PEP output. Sub-unit construction is used with
built-in test facilities for rapid maintenance. Direct connection
is provided for audio gear, remote-control, and so on.
For operation as a single set, or in the same vehicle as
a VHF set, only the receiver/transmitter 321 and low power
ATU are required. For operation in the same vehicle as a
second HF set the RF selector unit (RFSU) is also required.
The controls and front-panel presentation have been designed
to permit straightforward unambiguous operation without
the need for extensive operator training. Protection circuits
prevent damage from various hazards including local high
power transmissions. The station can be operated by direct
connection of audio gear, via the Clansman harness, or remote
lines, and so on. Provision is also made for RTT operation
and the remote-control of a duplex transmitter from the
receiver unit. In production since 1977 for the British and other armies.
More than 5000 have been manufactured for the Clansman system
with additional export orders worth in excess of £30
million. A £15 million order was placed by the UK
Ministry of Defence in September 1983. Tuning: required frequency available within 5s of setting
decade switches. Power output: High power: 40 W PEP (SSB), 25 W CW: Low power: 5 W PEP (SSB), 5 W CW
