For what its worth,
You might try to choke all cables connected to the K2. Sounds like RF is
getting is somewhere. You might have such a high RF field in your shack
because of your antenna system that it might be impossible to cure on the short
term Choking all the cables might be a start. I use RG174 for all keying
lines and such. You might want to choke your headphones as well. I have had
trouble in this area too until I got a more resonate antenna installed on my
city lot. It is a true inverted-L...around 130 foot long. You can use an UNUN
to get to the right feed point impedance or use a tuning cap/inductor
arraingement. With your Titan (goooooood amp) the components would have to be
pretty healthy. As for the second harmonic, I was in a 160 meter contest
several years ago where a guy came on and said we were 20 of S9 on 80 meters.
We were into a 1/4 wave verticle on 160 with a very good match. I think that
sometimes RXs are pretty good that --46 to -55 db down is not enough. He
ck, what
do I know though? These are just random thoughts. I've had a neighbor compain
that when she was curling her hair with a curling iron (coil of hot wire) that
she could hear me in her hearing aid!
