[TenTec] Titan tuning problem

[Hans Björneberg]

I am the owner of a TITAN 425 which forks fine with one exception.
On lower bands 160 and 80 meter the tuning is not stable, meaning
it varies with heat. During a QSO I have to readjust C1 a couple of
times. I suspect that heat is causing something to the capacitance
but not sure what. Can anyone please tell me whats wrong and how to
cure it, please.
