Yesterday I changed PTT-KEY to OFF- DTR so Logger32 would be able to key via RS232. Worked great however this morning, with the K3 turned on, I booted the PC. During boot, the K3 emitted about 3 sidetone beeps. Later when I tried to key the K3 via direct paddles I got zero power out. Turning the PWR knob revealed that Power had been reduced to the zero setting. I turned up the PWR via the knob and all was well. I guess this proves the importance of first booting the PC then turning on the K3.
