Thanks for your support Guy.
I have addressed this subject several times in the past (with no 
success). I often use diversity in contests  (ever since I have my K3, 
which carries #1255).

Now that the K3 runs the diversity form one VFO and the problem of the 
filter offsets seems to be solved, this is the last thing to improve.
