I have not had my K2 on for several months now due to the other things in my life. I turned it on this morning and started working K9OZ (another K2 Addict) and the audio started to dwindle. I had to crank up the audio all the way to hear the CW. I have check antennas, coax, and listen to another rig. The audio has just faded away. Anyone have an idea? Lee - K0WA
