Hi all, I have K2 #402, and am planning to upgrade it someday. But I was using it last night during the QRP-L fox hunt, and in its present state this K2 seems to be quite exceptional listening to weak signals (or static) on 40 meters.
For most of the time, when I had actually located both of the foxes, they were in the noise most of these times. I finally got both by waiting until propagation got momentarily marginally better. My strategy was that I figured that propagation would either get better (50% chance) or worse (50% chance) and it was no use transmitting until I could copy most of what the fox was sending. Why send when you can't hear the fox give your call sign back?(HINT!!). Anyway since I was using all the performance my K2 could give me listening to mostly static, I tried putting the preamp off. It is usually on all the time. What I found was that I seemed to hear the fox better over the static with the preamp off, but the volume was too low. With the preamp "on" I had plenty of excess audio volume, but with the preamp off I didn't have enough volume I felt necessary. With the preamp "on" I also tried putting the af volume on full and then reducing the rf gain slightly. This actually helped but I sensed that using the rig with the preamp off and having a little extra volume would be significantly better. So I wonder if I need more af gain in the rig or maybe a little amp on the way to the headphones. Or maybe I am imagining things and somebody with more experience can set me straight.
