[Elecraft] RS232 polling noise with MicroHAM CW Keyer

[Craig Rairdin]

I have a MicroKEYER that I use with my K2 and I seem to recall hearing that
noise when I was running it using my laptop but I don't get the noise when I
use my desktop PC.

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.
