VHF Automatic Direction Finder JMC DF-5500

JMC DF-5500

VHF Automatic Direction Finder Model DF-5500. Graphic and digital indication of bearing, reflection ref. course denotation up to the end. Indication of modulation mode of receiving signal. АМ - amplitude modulation; FM - frequency modulation. Course indication. It's possible to show a true course in case of connecting to GPS. Indicator ref. bearing - RELATIVE; and true course - TRUE.

Indicators of signal attenuation of received frequency, of received channel. Automatic regulation of strengthening level, built signal attenuator. User-programmable channels. 48 user-programmable channels can be arranged in band from 118-174 MHz in a mode of frequency or amplitude modulation.
