[Elecraft] My K1 is sick, please help!

[Hagood, Larry]

I'm in Japan and I brought my K1 along but it's developed a weird problem.
It happens on Rx and I think its in the AF stage but I could be totally
wrong. When tuning around any band and come across some QRN the audio will
blast a harsh static that sounds just like if I turned on a very poorly
shielded piece of HV electronic equipment right next to the rig. Then if I
turn the volume all the way down and then slowly back up it will be gone
until I get to about one o'clock or so and then it instantly blasts out
again and the volume has to be turned all the way down to make it go away.
It only happens with an antenna connected and CW signals don't seem to
trigger it, only broadband hash stuff.

Thanks a lot,
73 from JA land
