Makes no difference in my case. I also noice that it never happens when
the rig is cold -- in fact, just listening time doesn't count -- I have to
be transmitting a lot (like CQ-ing in a contest) before it happens. Once
it starts, it gets progressively worse. Originally, it was only noticeable
on CW, but now I notice it starting to get into phone as well.
