I got handed a 6550 for repair.
It won't change channels using the 16 channel knob.
I can't shag the feeling that somewhere in the software, there is an option to use, or not use the top knob to change channels. But I have swam thru all the software, and don't see it.
All the channels and banks are programmed correctly, I can read and write to the radio.
But it's not changing channels, staying on channel one in every bank of channels, no matter where the knob is at. I can change banks using the menu on the radio.
Anyone have an easy fix for this before I send it off to a repair shop?
