MX300 (MX-300)

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: IN-525A VOR/LOC/Glideslope Indicator & R-443B Glideslope Receiver IN-525B VOR/LOC/Glideslope Indicator (with backcourse light) & R-443B Glideslope Receiver
