During NAQP CW this weekend, I noticed a thump/click sound in my right headphone when using AFX. I tried a different (new) set of phones thinking maybe I had a bad diaphragm in the old set, but same sound. It doesn't occur in normal mono mode.
Too, the headphones feed is from the rear panel, not the front panel headphone jack.
I'm using firmware 3.23...
I hadn't noticed this before, but haven't used AFX for a while either. So not sure if it is coincidental or not...
Thanks,
Julius
