Stan,
?
Thank you for taking the time to explain how to troubleshoot my speaker issue.? Following your instructions, I sampled pin(3) and pin(5) of the LM386 with my scope.? I don't have much experience using a scope, so this exercise was a good learning experience for me.
?
I settled on setting the sidetone volume at 80 while using the speaker.? The volume is perfect with the case covers in place.? I set the sidetone volume at 50 when using my headphones.
?
I am really enjoying the portability and flexibility having a QMX+ with an ATU, self-contained battery and speaker.
