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. HTH Graham
