Regarding my CODEC issue. Coincidences can really throw you off the 'right path'. Connected my laptop to the IC-7300. The laptop has not received the latest Win 10 update. Still not working. That told me Win 10, at least this time around, was not at fault. Uploaded the IC-7300 settings from the SD card, problem solved. Why/how the IC-7300 configuration got corrupted is still unknown to me. The fact that it happened at the same moment as a Win 10 update made me waste 2 days. Well, not totally wasted. In my attempts to fix it, I did a major clean up on my desktop PC. I seems to be running better now.
