The Becker AR6201 VHF Transceiver is smaller and lighter than its legendary forerunner AR 4201 due to implementation of state-of-art DSP (Digital Signal Processing) technology. It is mountable in the 2 1/4 inch standard instrument panel recess, equipped with a highly efficient AM-transmitter, offering easy switching between the 8,33 and the 25 kHz mode. A built-in-test facility increases flight safety. The dual monitor mode allows scanning of two different channels.
