TECHNICAL DATA

Frequency range              1.5 to 29.999 MHz

Transmitter output power

Full         1000 W±1dB

Reduced              500 W ± 1 dB

Modes of operation

  • Frequency list scanning, programmable unrestricted
  • Frequency list scanning, programmable unrestricted with automatic jamming
  • Band searching, up to two bands simultaneously
  • Band searching, up to two bands with automatic jamming
  • Operation at single dedicated frequency, surveillance or jamming List of friendly frequencies (forbidden for jamming)             up to 96

Jamming modulation sources

  • Jamming modulation generator GEMOS
  • Cassette recorder
  • Telegraph key and
  • Microphone

Jamming signal types (from GEMOS)

  • Gaussian noise
  • Carrier frequency FM modulated by Gaussian noise (FM noise)
  • Linear FM signal (sweep)
  • Binary FSK signal
  • Tone
  • Impulses, generated in pseudorandom manner or with predetermined time duration

All jamming signal parameters (sweep width, sweep time, bandwidth, binary FSK frequencies, etc.) can be varied by software means

 

Signal classification

  • AM voice transmission A3E
  • SSB voice transmission J3E
  • Morse telegraphy A1A
  • FSK transmission F1B
  • Multichannel telegraphy transmission R7B
  • Unmodulated carrier A0 noise
  • Unknown modulation

The signal parameters like FSK mark and space frequency and the duration of Morse telegraphy impulses and pauses can be determined, too
