REMOTE CONTROL TRANSMIITER


Posted on Feb 5, 2014

This transmitter sends an FM signal in the 88-to 108-MHz range, with a tone of 19 kHz. This can be used to activate the FM MPX pilot carrier indicator, which can be interfaced to external devices. L4 is for use with a 15 CM wire antenna. L1 is 9 turns of #26 enamelled wire on a 1/4-W 10-k © resistor (carbon type), L2 is 2 turns wound over L1. L3 i
