The archives of this list contain many postings on cures for Scout drift
while the microcontroller is occupied with keyer duty.

Fan on the heat sink at full power seems to help.   There were in QST some
cap changes to stabilize the PTO with temperature coefficient caps.

Not going over 25 wpm is another sure cure.   And simplest of all:  Follow
the factory instructions and PAUSE once in a while in your high speed
sending to let the micro switch to PTO compensation!
