[Elecraft] K2 - NOISY POLLING

[Chris Page]

Does anyone else have a problem with noisy polling with their K2 when 
used with a computer logging program, and is there a cure for it?

I have two K2/100s which both have the 160m, NB and DSP options and 
one has the SSB option.  I am using N1MM Logger with an old desk-top 
(about 300MHz) computer under Windows 98 and when I listen to the SSB 
K2 on any band with the AF gain at minimum, I can hear a soft pulse 
every second or so.  This does not increase as the AF Gain is 
advanced and normally the sound of signals, etc masks it, but it is 
slightly annoying when tuning on a very quiet band.

I can just about hear it on my other K2 if I really listen hard for 
it but I don't think I would have noticed it on this K2 had I not 
first heard it on the SSB K2.  The problem must therefore be 
something to do with the SSB K2.

Gary Surrency suggested moving the ribbon cable between the K2 and 
K2/100 further away from the KSB2 unit and also try switching off the 
RTC (in the secondary menu).  I have tried both and neither make any 
difference and Gary suggested I now ask on here.

Thanks for any help.
