[Elecraft] K2 drift

[Julian, G4ILO]

I have never found a problem with my K2 drifting, even when operating data 
modes. It's the 10W version, of course. I think the problems of excessive 
drift only affect those with the 100W PA installed internally.

The BFO does drift when it warms up. I can tell this because the passband 
of the narrow filters shift and the pitch of the hiss that you hear changes 
slightly. One of these days I'll get round to installing the BFO stability 
mod I've got, to fix this. But I've seen enough posts from people who've 
installed mods and found their K2 no longer works to be a staunch advocate 
of "if it ain't broke, don't fix it."
