I noticed this problem on 40m using N1MM logger. I haven't used other
programs with RS232-like interface to the K2 yet. I removed the top
cover to see if there was anything simple like moving the RS232-like
cable that is internal from the front panel to the rear panel, but that
made no difference. I haven't done anything else to try to correct this
yet. I don't use logging programs very often, but it is somewhat
annoying when tuning across a quiet band. All signals I've worked have
been well stronger than this noise, but it is just another annoying
noise source to listen to (or try to filter out or ignore). I did
resolve some discreet noises by getting rid of my CRT monitor and
upgrading to a nice LCD monitor. Obviously that didn't help the RS232
problem though.

My newer laptop does not have a serial port and doesn't run DOS so I
got a MicroHAM CW Keyer. It works fine with my FT1000MP Mk5, but with
my K2/100 I get significant noise (like, S5 on the meter) on all bands
whenever the MicroHAM is polling the K2 RS232 for VFO/Mode data.
Has anyone else seen this problem? MicroHAM support says it's a known
problem with the K2 (?) and suggested asking on this list whether
there are any known fixes.
