TKM MX300G 760 channel transceiver and VOR receiver. Active and standby freq displays. Includes displays for localizer and marker beacon (separate receivers required, if desired).
Serial number 6989. Product was just repaired by TKM factory service and tested to factory specifications. Includes factory Airworthiness Approval (yellow) Tag dated 9/15/2015. I have flown with it and verified everything works (except localizer & marked beacon indicators - I\'m sure they work but have no way to test).
I have a tray for it if you want it (free w/purchase).

The MX 300 Series NAV-COMM is designed to directly replace the RT328T and similar units.

In most cases the MX300 will directly replace the RT308C, RT328A, RT328C,RT328D, RT328T, RT528A, RT528E and RT508A.
With a special adaptor (MX300/540) the MX300 will replace the RT517, RT540, RT514R, RT515R and RT515A-1.

TKM products were developed to provide high quality slide in replacements for many of the older Nav/Com\'s at an affordable price.

The MX series radios provide a direct plug-in replacement so that no installation modification is required.

All MX radios feature 760 channels with active and standby displays with flip-flop capability and memory storage for both Nav and Com frequencies.
