BENDIX/KING KX155 Nav/Com 14V GS - 069-01024-42
The KX155A gives you access to all 200 NAV and 760 COMM frequencies, along with its optional 40-channel glideslope. In addition to its standard use – offering both active and standby navigation and communications frequencies – the KX 155A incorporates a number of new control features. Program up to 32 COMM channels. Pre-selected frequencies are stored in a non-volatile memory circuit, eliminating the need for backup battery power. Other new features include a bearing-to-station mode and a radial-from-station mode. An internal Course Deviation Indicator (CDI) has been included for such times as when the external CDI is being driven by your GPS receiver, and the system now includes a handy elapsed-time and approach timer. On the COMM side, the KX 155A system gives you 10W minimum transmitter power.
