I had a similar issue, except my encoder noise was most noticeable around 5MHz. After testing and discussions with Wayne, it appears to be due to "hot synthesizers."
I do not notice this problem in the 6m band. 73 de James K2QI -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Graham Kimbell (G3TCT) Sent: Saturday, June 27, 2009 1:31 PM To: John Lawrence; Elecraft reflector Subject: Re: [Elecraft] K3 VFO tuning hash This noise was previously reported under the title "K3 Tuning encoder pulses and birdie problem" In my case it is only noticeable at the low end of 28MHz when there is a low noise level from the antenna or with a dummy load attached. Wayne suggested using the noise blanker on a low setting like t1-5, also tightening screws and tmp cables may help. In my case it seemed to get better when I installed the KRX3, but maybe cos I tightened up the screws and cables.
