TKM has developed a special niche in the avionics market. They make only direct replacement radios for common older avionics. This means that the owner of a TKM radio can replace the original radio at minimal installation cost, while enjoying convenience features such as frequency flip flop, frequency memory, and a bright easy-to-read display.

The MX-12 is the TKM radio designed as a slide-in replacement for the Narco MK-12A / MK-12B  NAV/COMM. Since it has a more modern design, it no longer requires the MK-12A / MK-12B's remote power supply. This saves weight, heat, and complexity, while boosting reliability. However, the MX-12 requires more installation effort than other TKM radios.

Per the TKM manual: "Since the remote Power Unit of the MK12A is no longer required, the existing cable to the Power Unit must be disconnected and the adapter plug supplied with the MX-12 must be inserted where the Power Unit was removed." We will include this adapter plug (see photo).

If you are inserting an MX-12 into a Glideslope installaton, there is an additional cable needed to interface with the Glideslope Receiver and Indicator. It used to be a simple matter to order this cable from the factory. However, they have run out of these cables and do not expect more. If you need this Glideslope cable, please let us know, and we will determine the additional cost and lead time.

Additionally, the MX-12 features:

• 200 NAV channels
• 760 COMM channels
• FM Immune (ICAO Annex 10)
• Simultaneous digital display of both active and standby frequencies
• Push button frequency flip-flop
• 100 memory channels
• 8 watts transmit power
• Automatic squelch
