The Narco MK-12E NAV/COMM is a bit more sophisticated than the MK-12D. Like a King KX-165, the Narco MK-12E can use its internal VOR/LOC Converter to calculate additional NAV information. This radio can display the digital bearing to and radial from the active VOR. This information may be displayed instead of the standby NAV frequency. Not only is the MK-12E less expensive than a KX-165, it also uses less expensive Narco Indicators.
The MK-12E has a bright gas-discharge display, with automatic dimming. This display shows simultaneous active and standby frequencies for both the NAV and COMM sides. The MK-12E NAV/COMM tunes in 200 NAV channels and 760 COMM channels.
This version also includes an internal 40 channel Glideslope Receiver, which will drive a Glideslope Indicator.
The Narco MK-12E also features:
- Solid state design
- Internal VOR/LOC Converter
- Remote DME channeling
- Push button frequency flip-flop
- Automatic audio leveling
- Automatic squelch
- Audio amplifier (for driving a cabin speaker)
