MCX-100 Model Numbers

The following tables show what the different model numbers mean for MCX-100 VHF/UHF. To determine the Frequency and Power check the model number in the charts below. If you have other information I will add it to the page!

Example -

    MB  - International Model Prefix, CANADIAN Made
    T   - Mounting Type, Remote Mount
    4   - Power 30 Watts

    00  - Synthesiser Step 20, 25, 30kHz
    A   - ??
    K   - ??

To decode the model numbers here are the keys for UHF and VHF radios. If you have other infomation, pass it along and I'll add it to the lists below. The last 2 digits for the model should define the range, but they don't seem to match up to the service manuals.

* For 2-9 Mode radios, you may be able to change them into
16 modes by removing the stop behind the mode select knob. The
display for the 10's digit can then be added, ie, a led or a 7 Segment
display can be wired into the missing digit slot to indicate channels 10-16.
