Well, a week or so ago I asked if people were hearing clicks in the
passband when listening to strong CW signals on 40 M. I saw the problem in
my Corsair II when tuned as much as 5KHz away from an s-9+20dB CW signal,
even when running the 250 Hz CW filter.
Anyway, I've done some more testing. First, the noise blanker wasn't the
cause. I hear about the same amount of clicking with or without the noise
blanker. With the noise blanker on, the upper end of 40 M is a mess, but
that's another issue. I still hear the clicking noises but not on all
stations. Some click all up and down the band (+/- 10 KHz or more), while
most signals are gone when I'm around 2 KHz away.
So I'm gonna say the problem is actual key clicks from non-TenTec
transmitters!!! :)

P.S. I had the pleasure of working AA1AC / VP9. The best part was the
AA1AC part, not the VP9 part!!
