Yes help, If it ain't one thing, it's another. Having just fixed the AGC problem in my K2 (2631), enjoying the beautiful radio, weirdness has again struck. I get high SWR on 40 meters after I cut the output down, to raise it again for full output. When I back the power off to minimum, there's the high reflected power indication, about 9 to one. When I run the power back up, the SWR again behaves. Souns like antenna glitches, no? The antenna is a big loop (240 feet) open at the top, fed with 450 ohm open wire line. I use an SGC 230, and the combination with my K2-100 has been perfect. When I back off the power, only on forty meters, the SWR goes crazy. Only on forty. All other bands tune thru the tuner just fine. So, thinking still it must be the antenna, I ran the K2 into a dummy load. Same Thing Happens !!!!!!!!! Is there a bad solder joint in the low pass filter on the K2?; that lets it operate at some power levels but shows high levels of spurious transmitted signal sometimes? I don't get it. Any ideas?
