GAZ
69 OREL-1 (Eagle-1)
Work
on the project for the mobile radio prelengator for long and
medium frequencies, called Orel-D commenced under the USSR
Ministry of Defence decree number 827/367ss 1959. The contract
number 21 of 30/07/1959. In 1960 the GAZ 69 was selected and
the radio-transparent wooden hardtop covered with the canvas for
camouflage was designed. By the end of 1962 the
sketch-engineering design was finished and the first prototype
was ready for laboratory tests. The apparatus "Orel-D"
was a radio direction finder with a visual bearing indicator,
with the ability to work on the move and stationary. Designed
for finding the direction of radios transmitting in a range of
frequencies between 150 kHz to 1900 GHz.

It
provides: A) simultaneous and independent reception and
station search by two operators using omnidirectional
antennas; B) visual and auditory direction finding by one of
the operators while the second operator can search and identify
on non-directional antenna. The equipment consists of two
radio stations, a visual display, blocks of antennas with a
goniometer, motor and electrical components.
Re-designed
apparatus now called "Orel-1" was placed in a GAZ-69E.
It consisted of a direction finder "RP-5" instead of
the dual-finder, and the transmitter "Tvertsa." The
rest of the equipment of the station "Orel-1" was the
same as on the "Orel-D." Power for the entire station
was provided by a battery pack 6ST-54 that provides operation
without recharging for 20 hours. Production started in 1968. It
is estimated that about 10 units per year were produced.
