[Elecraft] K3: Strange VFO Behavior

[Ed K1EP]

Reminds me of the old comedy routine -

Patient: Doctor, it hurts when I do this.
Doctor:  Don't do it.

If I am casually tuning around, hunting DX and I want to check on two 
different bands (like the current multi band/op dxpeditions), the 
easiest thing for me to do is put one freq/band in one VFO and the 
other freq/band in the other VFO.   Hitting A/B allows me to 
conveniently switch between the two.  Seems fine as long as I don't 
accidentally hit VFO B in the process.  I don't have exceptionally 
fat fingers, but I do manage to hit the wrong knobs once in a 
while.  I don't think that it is good behavior for this to 
happen.  What if you don't purchase the second receiver?  Are you not 
allowed to do this?
