Hi Bob
I work in Motorola Plantation Depot for 8 years working on Maxtrac radio,
They use to call the convention unit MAXTRAC and the trucking unit MAXTRACS
with a "S" The Maxtrac 900 has a common audio problem specially the 900
trucking converted to conventional, on the volume control there is a module
Motorola call it hear clear, module, at one time there is a bad batch of hear
clear module, even after replacing a new module it never last because it belong
to a bad batch, replacing that module to clear up the problem. hope this help.

I ran my 900 MHz MaxTrac up. No setting in RSS for the hang-up box. I
wonder why they did away with that.
I also discovered that my radio has a serious receive audio problem at the
moment; very weak, very distorted. Almost sounds off-frequency or like a cap
has gone leaky and has upset the bias in the RX audio chain. If it's not one
thing, it's another.
Adding a short piece of wire across the two pins in the MIC jack is very
easy. You only need a T15 driver to remove the front panel, then a T10 driver
to remove one screw that holds the VOL/MIC board into the front. Unplug one
connector and you can work on the assembly on the bench.
