- Anotaciones
- The RT-175A FM-transceiver is a main component of the PRC-9 radio-equipment. Only in literature we can find the name PRC-9A, but on the equipment the -A suffix is never present.
Frequency range is 27-39 MHz, FM (F3), 1 W.
VFO-tuning and a crystal calibrator stage giving 4,3 MHz checkpoints. In the receiver-part we find 2 RF-stages, 4 IF stages, a discriminator FM-detector with 2 germanium diodes, a squelch-circuit and a pulse sweep generator to control the transmit frequency.
At the top we find all controls and connectors for the headset and 3 antennas: long whip AT271, short whip AT-272, and a ca. 50 ohm BNC-connector.
The set was designed for field use with a 3,65 kg multi-voltage battery BA-279, or for vehicular use with a 24 volts PSU and audio-amplifier AM-598.
All tubes, exept the noval 5A6, are of Special Quality subminiature B5A type. The factory aligned complete IF circuits, including the mini-tubes, are housed in sealed metal cans with B7G-pins, as well as the discriminator-circuit and the pulse sweep generator.
Similar, but with different frequency-ranges are RT-174A / PRC-8 20-28 MHz, and RT-176A / PRC-10 38-55 MHz.
A variant with different circuitry and 16 tubes, but a look-alike, is the RT-175 / PRC-9. Another variant is the 1 channel, 30-42 MHz, crystal controlled RT-339/PRC28.
