Hi
codec gain settings, broken or missplaced red straps, damaged cables are the only reasons I can think of.
You can send me exported settings(html) files if you want me to take look
73 de mike
I went over the straps and jumpers again last night with my voltmeter to check continuity from the straps to the RJ45 AUX/MIC port. All good with that. I noticed that that mic ground and ground on the control rrc are shorted but on the radio rrc they aren't. Don't know if that has anything to do with it. Attached please find pics of the radio setting. I will do the export as soon as I get home.
