Thanks for the great commentary along the way Eddy. Hope to work you
one of these days with the "new" sound.

*/Hi Guys,/*
Yesterday I took my R-4 receiver & /T-4X/ transmitter---the one with
the ailing PTO---to the lakeside cottage for a bit of a field trip
operation on 40-meters, to validate the effectiveness of my "fix" to
the frequency stability...
After some 5 hours of off & on CW operating---and all-the-while
monitoring my actual signal on the receiver---it pleases me to no end
to report that the intermittent warbling / raspiness / instability of
my signal is now */GONE...!!!/*
I made a half dozen or so, QSOs, & specifically asked for a critique
of what I sounded like in the contacts I made. To a man, each
respondent said that the signal was good---no chirp, no clicks, no
/NOTHING/ that might be considered to be "...untoward". Two of the
fellows that I worked even complimented me on the great "/Drake/
sound" coming out of the T-4X, & at least one of them expressed regret
that he'd sold his own /Drake Twins /years ago.
One comment that I received---meant to be a compliment, I'm
sure!---was that the /T-4X /sounded like an old /Johnson Valiant/
transmitter "../.on its best day, when brand new/". I personally can
remember with special fondness the note those old rascals emitted, but
only /WHEN OLD! /Hi Hi.
*/LESSONS LEARNED:/*
(*1*) Always suspect /MORE/ than just one single issue with your PTO
in the event of "raspy warbles". Mine was two-fold here, i.e. /TWO/
bad solder joints with the 3000-pfd. silver mica cap, and a consequent
bad solder joint with the 33-pfd. temperature compensating capacitor
(probably my own fault, after my first "fix" to the s.m. cap!), and,
(*2*) Do not discount the "ill effects" that circuitry /EXTERNAL/ to
your PTO might have upon your signal. I discovered yesterday that I
have some serious cleaning / inspection ahead of me in the matter of
the function switch of my /T-4X/: by rotating the switch
ever-so-slightly off of its "normal" detent, I could induce raspiness
& a shift of the frequency of the PTO rather easily---/and with shades
of the original ailment! /These rigs are wonderful, to be sure, but
they /ARE/ fast-approaching the half-century mark in age(!).
Rigs---like the owners of same---need a bit of TLC as they grow
older. Hi Hi.
I hope this personal saga of mine might serve to inspire others not to
give up. Many thanks to all who generously & graciously took the time
to share their own personal experiences with me, during the course of
my journey of discovery here...
