JAMMING by Rimantas Pleikys
Technical specifications of some Soviet made High Frequency point to point transmitters that were also used for radio jamming:
|A1A, R3E, A3E, B8E, F3E, F1B, F7B|
SHORTWAVE TRANSMITTERS, OF USSR MANUFACTURE, USED FOR HF BROADCASTING, COMMUNICATIONS, AND/OR JAMMING
|TX type||Power, kW (AM)|
|VIAZ-M2 (M2 OP)||5|
Note: As far as is known, serial communications and broadcast transmitters were used for jamming purposes. There is no information available on the use of any specially designed transmitters or antennas for the above purpose.
It is believed that in some cases jamming transmitters were connected in pairs, resulting in higher power: 2 x 15 kW, 2 x 20 kW, or 2 x 100 kW. Frequency modulation was widely used in jamming. As in the case of the Sitkūnai radio station, sometimes the Soviet Union used shortwave radio broadcast transmitters for jamming. The typical power level used for skywave jamming was 20 to 200 kW.
