MX 170C NAV/COMM

The MX 170C is designed to be electrically and mechanically interchangeable with the KX170/175 series of NAV-COMM'S. The channeling outputs are for 40 channel glide slope (King Glide Slope) and 200 channels (King Slip Code). The early model KX 170 has 2 out of 5 channeling and some interchangeability problems may result. The MX 170C operates on 13.75 vdc with 7.0 Adc maximum current in transmit.

The MX 300 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.
The NAV Demod output pin is on pin BB on J4 on the MX 300 and on the RT328T, RT328D, RT528E.
The RT308C, RT528A, RT328A & RT328C, however use pin L of J3 for the Demod output.
The MX 300 can be modified to output the Demod on pin L of J3.
The MX300 operates on 13.75 vdc with 7Adc maximum current in transmit.
The special adapter (MC300/540) can be placed in existing installations and locked in place.
The MX300 can then be installed by simply sliding into the MX300/540.

The MX300T NAV/COMM is designed to replace the RT328T and similar units. In most installations the MX300 will directly replace the RT308C, RT328T, RT328A.. The MX300T is available with beige faceplate. The MX300T operates on 13.75 vdc with 7 Adc maximum current in transmit.
