Jack - I've been using my K3 with my ALS-600 for about 18 months now. My ALS-600 takes 65 watts drive to get full output, so I just put a 2dB attenuator in-line whenever the amp is turned on (relays switch in the attenuator automatically). That way I can leave my transmit power always set to 100 watts and not worry about the drive level. Info on my auto-switch attenuator is in the "Articles" section of my website at www.ad5x.com.
I modified my ALS-600 for QSK operation. The QSK relays operate in less than 5ms, which is within the 8ms default delay of the K3. So this all works fine as well. Details on the ALS-600 QSK mod (which is very simple) are in the "Equipment Modification" section of my website.
