Overview
This page shows how to modify the Motorola MC micro to turn it into a fully-fledged ham-radio transceiver.
The simplest modification comprises the replacement of the memory device (EPROM) which contains the control program of the transceiver. In a second step it is then necessary to realign the RF frontend of the radio to the desired frequency range (430 - 440 MHz or 144 - 146 MHz), if this was not already done before.
After this modification, the radio is ready for FM voice transmission and reception. The feature set can be further enhanced by employing other modifications. For a complete list have a look at the modification matrix.
