[Elecraft] K3 Weird Intermittent Problem

[Ken K3IU]

My K3, s/n 202 with all mods including the new synth boards, 
is presenting no noise as has been described in the several 
emails on this subject. Of course there is a lot of 
indescribable noise in the upper part of the band that I 
don't understand, but I think that is my problem and not the 
radio.:-)
73, Ken K3IU
