[Elecraft] K2 #4970 is now a K2/100

[Fraser Robertson]

John, our club's K2/100 does the same thing - high current on topband, but 
it seems normal on all other bands.  I mentioned it on here some months 
back, and received some useful suggestions to try, but I never did find 
anything wrong as such, or a cure for that matter.
