Is it possible to key the K2/100 for CW QSK operation with the Alpha 99. If
so, how should the delay be set in the K2. I would rather key the K2 first
rather than keying the Alpha 99 and running the keying line back to the K2.

However if you get a QSK amp, like some of the Alpha's or TenTec's, you can
retain the degree of QSK that the K2 or K2/100 is able to provide.
Sure.
Just key the K2/100 and take the AMP T-R output from the back and connect
it directly to the T-R input of the QSK amp.
I have an Alpha 76PA in which I installed retrofitted ETO QSK, and I've
keyed it in this manner since day-one which no problems whatsoever.
It is best to NOT key the amp and allow it to key the K2/100. Although
that's how ETO used to want you to do it with their Alpha 78, I never found
it to work correctly. However, using the newer QSK rigs, which offer a few
mS of pre-keying of the T-R line before RF is generated, keying the rig and
allowing IT to key the amp works just great.
