The Bendix-King KX-155 is an industry standard. A bright gas discharge, flip flop display shows 760 Comm and 200 Nav channels. It's available with or without 40 channel glideslope receiver in 14v and 28v versions. This is a very well engineered workhorse with an excellent reliability record and is one of the top radio models ever built.
Push button frequency flip-flop with display of active and standby NAV and COMM frequencies makes tuning the KX155 a simple task. Models are available with built-in audio amplifier, 25 or 50 kHz COMM receiver selectivity and can be used the KI-209 VOR/LOC/GS indicator.
The KX 155 boasts a minimum COMM transmitter output of 10 watts minimum. Operating on all 760 existing frequencies (118.00 to 136.975 MHz), the system is expandable to 139.975 MHz to accomodate possible future allotions.
'Flip Flop' frequency switching (for both NAV and COMM sections) is standard, of course. Direct tuning and a remote transfer switch are also available.
Fully self contained, the compact KX 155 is just 2.05" high by 6.25" wide.
