[TenTec] PTO Drift Problem

[bames@mecasw.com]

>>The problem will ONLY exist with an outboard keyer if the PTO temp comp
caps have changed or will installed wrong to start with. That MIGHT cause a
PTO to go out of recapture range over some time and temperature extreme
excursion.

The jump is when the up comes in to take f correction control and the PTO
has gone so long on its own that it is on the hairy edge.

Incidentally, my Scout has never drifted, even at Field Day on battery
power in a tent last June.  Guess I am lucky, it is about 2 years old.

==================

I agree but that implies that if the PTO is not drifting then it dosen't
make an difference which keyer is used. The question, as
I see it, how do you evaluate your PTO to determine if it is no longer in
spec and requires repair?
