Dirty switches can cause all kinds of strange problems in the Drakes. GL
Eddy. I hope that cures it.

Hi Again All,
Well, to-day I could have SWORN that some demon had taken possession of
the PTO in my T-4X transmitter, & that it was sent to this earth with the
express purpose of taunting me...!
I mentioned before that last week I re-soldered a visibly bad connection
of the 33-pfd. temperature compensating capacitor to the board of my PTO,
and that---so far!---it appeared to be the proverbial "silver bullet" in
fixing the "warbling". Well, this morning---at the very moment that I was
seriously considering taking the "4-Line" on a road trip to the cottage to
test
the PTO "in the field"---the frequency suddenly jumped a coupla KHz, and
was raspy-sounding...!
Oh no, here we go again! ("Why do the gods taunt me so...?!").
Turns out---I think!---that I was monitoring the T-4X with the function
switch in the "Tune" position. By wiggling that switch ever-so-slightly, I
could make the frequency jump a prescribed amount of KHz----exactly the
amount that I get when switching the mode switch to Phone.
I wonder if a dirty mode switch may have contributed to my initial
confusion in this whole matter...?
The testing continues...
