I would disagree the 80 Channel is completely compatible with the 40 Channel unit.
We have been running 80 channels narrow band from the start and have found compatibility problems when 80 channel units are being used in a group of 40 channel units.
Some of the issues have been soft transmit audio and lack of range from our 80 channel unit and broken transmission from 40 channel units that we receive on our 80 channel unit.
We have over come the compatibility problems by programming our radio to be 1-40 wide band and 41-80 narrow band.
The compatibility problem is starting to raise it's head by people who use their radio's in a group of 40 and 80 channel units even to the point of transport companies and large pastoralists refusing to buy 80 channel units and seeking secondhand 40 channel units.
