Keith,
One thing you might look at, as you said, is the tuner.
I seem to recall wayyy back when I first got my ticket I had a very
similar antenna issue. I can't remember the details too much, but it
turned out the tuner was arcing. It was an MFJ tuner of some sort. I
distinctly remember hearing a buzzing noise from somewhere in the
shack when I was keying my Century 21. After listening closely you
could hear popping coming from it.
I traced it to the tuner and pulled the cover off. Once I did that
the problem went away. Putting the cover on made it happen again, so
I turned the cover upside down so I could see inside and watch. There
was a nice 1/8" arc between the coil and case. The fix was easy - I
tried various things and ended up settling on a piece of cardboard
between the coil and the case. It was enough of an insulator to stop
it. Of course, I was just waiting for the day that the cardboard
would ignite, but it never did.
