Abstract.   An investigation on noise immunity of digital demodulator with bearing and clock frequencies tuning out is performed with the use of ADS. A prototype of radio station for the VHF range is developed, and possibilities of its application as a part of radio communication system equipment operated in frequency slot pitch of 6,25 or 3,125 kHz are tested experimentally.
Keywords: VHF radio station, GMSK, narrow-band reception, coherent demodulator.
