R-1051B Radio receiver, frequency range 2-30 MHz, 2-4 microvolt sensitivity, direct digital frequency synthesis, 0.1 KHz tuning increments, modes of operation USB, LSB, ISB, AM and FSK. Bandwidths: 3.1 and 6 KHz depending to operating mode. Operates from 115 VAC 48-450 Hz 55 Watt. Made in USA by General dynamics.
The R-1051B is a Triple conversion Superheterodyne HF receiver. Solid state construction except for two 6BZ6 tubes, which are used as the RF amplifiers in the front end delivering excellent performance and immunity to signal overload. The receiver is isolated against signal leakage to prevent enemy detection of the local oscillators.
The frequency selection is done by turning mechanical decade knobs. The Mhz stage is tuned by an internal motor. Frequency stability is 1X10-8 per day! The B model has a 100 Hz synthesizer which can be unlock for accurate tuning.
The receiver is supplied tested and operational Grade 2. Grade 3 Untested may also be available, please E-Mail for details.

The R-442/VRC is supplied in good working order Grade 2. Some accessories and cables are also available.
Specifications: Transducer type: moving iron. Sensitivity (into 150 ohms load): -51dB nominal re 1V for normal speech. Impedance: 155 ohms ?20% at 800Hz. Frequency response: rising to approx. 2.5kHz for higher intelligibility. Noise exclusion: a white noise sound field of 120dB produces an electrical output 6dB less than the speech output quoted.
The units are supplied as a pair, one MA-4230A Morse Encoder and one MA-4231 Morse Decoder and in very good condition, like new.
The MA-4230A Morse Encoder Unit enables a message to be transmitted in Morse code. The Morse message is entered using an alpha-numeric keyboard therefore no knowledge of the Morse code is necessary to operate the unit. The MA-4231 Morse Decoder decodes the Morse code being received and displays it one letter at the time on its red dot matrix display or sends it to a printer. Both units are powered by an internal rechargeable battery which provides approximately 16 hours use without recharging. The case fully sealed and waterproof.
Message entry is done via the keyboard which contains forty three Arabic alpha-numeric tactile keys, including SP space and seven function keys. Three indicators are provided showing when power is available, data is being emitted, and when the store is nearly full. The power indicator extinguishes when the battery voltage is low, and when the unit is switched off.
1024 character, non-volatile electronic memory Message store, Normal Transmission speed of 15 w.p.m. and High Speed 120 w.p.m. Keyed Tone Data output - Normal frequency: 1.0kHz. Amplitude: 20mV ? 3dB from 300 source. Contact closure Data output - normal speed only Contact rating 0.5A max.
These Battery Cassettes take 10* standard or rechargeable "C" sized batteries to power the radio set and is also fuse protected and simply clips on to the bottom of the TRA-967 radio set. These MA-968B Battery Cassettes are supplied in brand new condition, NOS. Available in limited numbers, batteries not included!
The radio incorporates a built-in test sequence which automatically checks transceiver performance and displays results.
A 16 Kbits/s data capability is also incorporated in the transceiver and options extend the facilities to include built-in pseudo-white-noise encryption of both data and speech.
The front panel which is removable provides full-control over a simple serial data line. It can be relocated and mounted anywhere on a tank with a radio located in the hull or a similar remote position. The control panel also provides control of two radios from a single remote position.
The control panel enables selection of operating frequency and up to nine pre selected channels as well as encryption codes and the transceiver mode. An alphanumeric display gives read-out of frequency and status.
First announced in September 1979, the VRM5080 was in production by Racal Radio Ltd in Reading, England for users worldwide and by Kapsch for the Austrian Army. These radios are supplied in good used condition, tested and operational Grade 2.
