2009-04-08 Thread DAVID POWELL
On my K2 (#3014) I hear signals and noises while tuning across 160m with the antenna disconnected. The worst is a strong but unstable signal that moves from about 1850 kHz to about 1910 kHz during about 15 minutes after I switch on the radio. I accidentally traced the signal to U10C on the contr

Okay...had to give it a try. Just worked him on 40m after about 3 minutes of calling. 2.5 minutes spent calling "blind." Then I heard him call a G3, found the G3 on VFO B (no dual rx) and I was the next call. Doug has confirmed that his QSO followed mine. I was using my K2/100 at 100W. An Ele
