Stuart, et al,
No, we are not imagining the drift problem. I use an external
keyer and I get QRH reports all the time on CW. When at my
home I monitor my Scout with my Paragon and I hear it first
hand.
In addition, I've done cold-to-hot tests using an external
keyer and a frequency counter and have recorded shifts of
up to 150Hz in pathological situations.
Even when using an external keyer, the processor needs
a 60 ms or so gap to keep things under control. If you
deny the processor of that time, as my worst-case test
did, then no correction occurs.
It's a great rig, and its stability is OK for most CW
situations. But there is a real issue which can't be
attributed to people's imaginations or the QST review.
