The only difference is the label and what the switch label says. The 16 channel and the 8 channel clamshell head are electrically the same. You may have to pop the lid on the transceiver and there is a jack on the front interconnect board where you plug in programming cable, click here to see where. Now, don't email us asking why this is the cable since you can't find anywhere to plug it in to. You can plug in a Radius microphone and use it to key the radio, talk on the radio, etc, it's the SAME THING.Ĭheck out the programming cable. The M400 Programming Port is the same as a standard Maxtrac / Radius Mic Jack.
The M400 is a suitable radio for use in the 450-470MHz band, but it IS internally different than the Maratrac. The Maratrac on the other hand has no problems operating in the amateur band as we've been told. When the radio was programmed, it received beautifully in the ham band, but put only milliwatts of power out.

This appears to be a firmware or software limitation. Something in the Radius M400 does not allow the PA to operate outside the specified band limits of 450-470. OVL file of the standard software, and by using the lab software, and here were the results: The radio was programmed both by modifying the.
The Radius M400 does NOT perform very well out-of-band, at least with the UHF 450-470MHz model that was tested. The standard Maratrac & M400 software does not allow out-of-band programming by using the SHIFT key, but the Maratrac Lab software allows direct out-of-band frequency entry.
The Radius M400 uses a MaxTrac / Radius type VCO board, whereas the Maratrac uses a unique VCO board specific to it. Although they do use the same software, the VCO boards are physically different. The Radius M400 is actually NOT the same radio as the Maratrac. The Maratrac and Radius M400 Mobiles The Maratrac and Radius M400 Mobiles
