K3 very loud pops on 80m

[Allan Taylor]

I have K3 S/N 740 and reasonably current firmware (late 2009). As it
happens, I used the K3 for the first time on
80m last night during the CWT mini-event. During the appx. 20 minutes
I was on 80m, I heard several VERY LOUD
pops. They weren't sustained but were dangerously loud. The first few
occurred with headphones on. I resorted
to speaker operation after that. This has never happened on 40 or 30m
where I have principally been operating with the K3.

Is this a known problem? Am I missing a firmware update?  This was not
nice at all.

1.  If AGC was used, do you have CONFIG: AGC PLS = nor?
2.  If AGC was not used, do you have CONFIG: AF LIM = 18-20?

Without wanting to start a thread on this subject, I want to say that I can't see any
reason not to always load the latest beta release. As a field tester I always load the
latest pre-beta code as soon as Wayne and Lyle make it available, and I've /never/ been
seriously 'burned'.

Each new version contains fixes for problems and new features -- and it's easy to go back
to an earlier release if you wish.

Just did a version check on the _ftp.elecraft_ (ftp://ftp.elecraft)  site
and it says the current versions  for the K3 are MCU 3.76, FPF 1.07 and DSP
2.52
 
Not sure why the version differences but I think I did see 3.78 and 2.54  
Betas released.
