Still having issues with repaired unit

Hi,

I had thought that the issue was fixed with some of the suggestions about the simulcast changes. I have done all that was suggested, but I am finding I still have issues.

This morning, it was working fine for hours, hearing all calls, etc...........It suddenly went silent. After a bit, I realized it is never THAT quiet and put on the scanner app, where there were clearly calls going out.

I have been watching it now for the past hour.....it stops on the channel for the appropriate amount of time for the calls going out on scanner app.....but no sound at all out of scanner.....

This is what I sent it to repair for....the intermittent sound........

Is it possible that the speaker or something of the sort is going bad????? Not sure what else could cause it to work fine for hours than just stop...Do I need to send it back for repair again? or what???

Thank you in advance for your help.
