Communication Options
The radio station provides two-way communication with an equivalent radio station in a medium-rough terrain in the daytime. The design and layout of the radio station allows the use of surrogate antennas. To the radio station were attached:
- whip antenna of 4 or 6 elbows (length 1.5 - 2.2 m)
- L-shaped antenna with an inclined counterweight (two beams with lengths of 14 and 9 m).
Possible transmission distances depending on the antennas:
- Pin: telephone up to 8 km, telegraph - up to 16 km
- Dipole: by telephone up to 15 km, by telegraph - up to 30 km
- Ray: telephone up to 6 km, telegraph - 12 km
Application
The radio station was produced from October - November 1941 until the end of World War II by the Gorky State Union Plant No. 326 named after M.V. Frunze (in 1943, 7,601 copies of the 12-RP type and 5839 copies of the 12-RT type were produced). Since 1942, tank radio stations 12-RT and 12-RTM were produced on the basis of this radio station, which were installed on light tanks and self-propelled guns of the SU-76 type . Radio stations 12-RP and 12-RPB were installed on the armored vehicles BA-64 .
