Product Description

When you want to upgrade your radios, one of the common barriers is the cost and hassle of installation. Wouldn't it be great to just slide a replacement right into the existing rack? If you have thought this, you should know about TKM.

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 quickly and easily replace the original radio at no installation cost, while enjoying convenience features such as frequency flip flop, frequency memory, and a bright easy-to-read display.

The MX-385 is the TKM radio designed as a slide-in replacement for the ARC (Cessna) RT-385 and RT-485 series of NAV/COMMs. This radio is available with either a black or tan faceplate, to better match your radio stack.

There is more to the MX-385 than just painless installation. It 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
  • 10 memory channels
  • 8 watts transmit power
  • Automatic squelch

These are the most common indicators used in MX-385 installations (the same as with an RT-385 / RT-485 installation):
