Got it going dinking around in some settings and sound levels. No idea why anything changed as this was all hooked up and running on another Yaesu. Murphy I suspect.
Over the last 6-8 years I've set up some combination of new radios, new interfaces, and new computers maybe 16-20 times. And I think that EVERY time I've done it, I've had the physical connections set up correctly in a couple of minutes, but there's always some little setting that isn't quite right. Like enabling "digital VOX" on my 950, or adjusting the sound card output when switching from one T60 laptop to another T60. Finding and fixing that one little glitch takes a LOT longer than the physical setup. And once it's done, everything works just fine.
At least these days I KNOW to expect the "one little glitch" and I know I'll spend 20-30 minutes figuring it out before the new setup works properly. :-) At first it was frustrating; now it's just part of the routine. :-) 73! --ken
