FM BROADCASTING TRANSMITTERS  ” MARK” 

It is intended for the broadcasting in FM band. The system transmits stereo and mono radio  programs.Frequency synthesizer with digital indication allows the discrete  tuning with a step 25kHz. Transmitters are produced in three modifications:

“MARK-66”; “MARK-88”; “MARK-100”.
