Minor problem or K2 design quirk?

[Ken Bessler]

For the last 6 months, K2 #4913 has performed almost flawlessly - almost.
Several times, I've returned to the shack and turned up the AF gain to find
that the XFIL setting had changed.

See, I never turn 4913 off - I just put all the controls and filters to a
default setting, stow the
mic and paddles then turn the AF gain down all the way. It's an old
habit....

So, I come back to the shack to find XFIL set to 1 yet the rx audio is very
narrow. Cycling through
the XFIL selections, returning to #1, restores the audio. This has happened
about 4 or 5 times
since March.

Anyone with a guess?

Ken,

I can only guess, but that kind of behavior strongly suggests an
intermittent connection (read = bad solder joint) somewhere.  I only know of
one other person who leaves their K2 powered on all the time - and Steve
follows this reflector, so perhaps he will provide his experience.

I don't yet, but I was considering leaving mine on 24/7 with some
self-written software to scan a few beacon frequencies looking for band
openings.

I'm therefore also interested to hear how I might be affecting the life
expectancy of the rig. I'd probably be band-changing more often than
most of the other 24/7 K2s too, so any info on the expected lifetime of
the relays would also be much appreciated.
