[arm-allstar] motorola gm350 4 channel radio

[Les Barker]

Hi Doug

Unfortunately I have tried all the obvious solutions without success.

I did download the windows exc file and burn the resulting image. Still no
luck!

I seem to be having my usual problems with the RPi.

Will the image work on a Pi Zero? Just a thought.

I'll just have to keep looking for solution.

Alan,

 From what you saying the COS looks to be working correctly. Is there any
chance you have the RX and TX audio lines reversed? I don't have the radio
connections handy but maybe someone else does.
