CommentsThere is no Rack and Connector included with this radio, as it is designed to use your existing ARC (Cessna) RT-328D / RT-328T hardware.

We offer the option of ordering a brand new MX-300 for you. We would have this radio shipped directly from the factory to your shipping address.


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-300 is the TKM radio designed as a slide-in replacement for a variety of 14 volt ARC radios. The most common replacements are the following radios:
  • ARC RT-328D
  • ARC RT-328T
  • ARC RT-528E
If you have an older 14 volt ARC radio, we may be able to supply an adapter that allows the MX-300 to replace it. (Please contact us for price and availability.)

This radio is available with either a black or tan faceplate, to better match your radio stack.

There is more to the MX-300 than just painless installation. It features:
  • 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-300 installations (the same as with an RT-328T installation):
    For VOR/LOC installations:

  • IN-514R VOR/LOC Indicator
  • IN-514B VOR/LOC Indicator (with backcourse light)


  • For VOR/LOC/Glideslope installations (requires an R-443B Glideslope Receiver):

  • IN-525A VOR/LOC/Glideslope Indicator
  • IN-525B VOR/LOC/Glideslope Indicator (with backcourse light)
If they are not already installed with your original ARC NAV/COMM, you may also be interested in a Glideslope Receiver or Indicator to use with this MX-300.
