K3 - sub balance and LOUD audio crashes

GW0ETF
I've been liking the feel of the Ab - Ab setting for the Main/Sub balance setting lately; having AFX operating simultaneously on A and B with SPKRS=2 while mixing with the balance control sounded excellent.

But I'm sure this afternoon was the first time I used it in transmit with sub/split when I tried calling P49V on 17m. So I was alarmed to be assaulted by random and LOOUD audio crashes as soon as I started keying; seemed to chop up the keying too. Sounded serious but at least no smoke and in fact it was the same with the power wound down to zero.

Seems there is a problem with the Ab-Ab/SPKRS=2 combo. Changing SPKRS to 1 cures it as does setting the balance to A-Ab or Ab-A so presumably it's a software issue. Running f/w 3.68 here and I was using the internal keyer.

Wonder if anyone can reproduce this....but watch your ears if you try!

73,

Stewart, GW0ETF (K3 #145)

Happy ending 'cos once I sussed out what was going on I worked P49V on A-Ab......

Stewart,

I had this problem a while ago and thought it had been cleared up, but "it's
ba-ack," perhaps because I started using Ab-Ab with Sub and split again
recently. Doesn't matter if I use CW or SSB.

I'm running the latest beta FW.
