Mike, all
Just a round trip ticket to what I found.
It took me a while to get to the bench...... school has started... busy, busy.?
I did change out the BS170s when I found the tuner (MFJ969) bought new 26 years ago has a bad solder connection in the back of the large induction coil.
The roller bar was not making connection. That's why the error was intermittent and all over the place.
I noticed this had effects on the other radios in the shack I didn't catch right away.
I thought it was my imagination or......... age? Nah.... couldn't be that?
I started checking everything.....?
I put on an auto-tuner from another maker and found no problem with any radio including the QDX.?
The change for the BS170s was just a precaution.
The unit from MFJ was repaired after I found the bad connection.
All is well with the world and back in the air.
Thanks for your help and encouragement.
