The receiver function tunes from 100-1750 kHz across 4 bands, which were selected by rotating the center knob below the frequency band window.  The center knob rotates a flexible shaft connected to a rotatable loop antenna.\u003c\/p\u003e\n\u003cp\u003eThe AN\/ARN-6 system evolved over time, originally using a control box similar to the BC-434A, and then in 1950's versions, using a smaller module (C-1514\/A) without the signal strength meter integrated into the cockpit communication console with a much smaller loop antenna (AS-313) without a radome.  These were made by Bendix and Magnavox, but this unit does not carry the manufacturer's name on its data label.\u003c\/p\u003e\n\u003cp\u003eThe AN\/ARN-6 system of post WWII-vintage (see diagram) typically consisted of the following components:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRadio Compass Unit R-101\/ARN-6\u003c\/li\u003e\n\u003cli\u003eMounting MT-274\/ARN-6\u003c\/li\u003e\n\u003cli\u003eIndicator ID-91\/ARN-6\u003c\/li\u003e\n\u003cli\u003eIndicator ID-92\/ARN-6\u003c\/li\u003e\n\u003cli\u003eCoupling Unit CU-65\/ARN-6 (2)\u003c\/li\u003e\n\u003cli\u003eControl Box C-149\/ARN-6\u003c\/li\u003e\n\u003cli\u003eLoop Antenna AS-.141\/ARN-6\u003c\/li\u003e\n\u003c\/ul\u003e\nThe unit is in exceptional cosmetic condition and all mechanical features appear to operate.
