Works great here Wayne. My antenna was a little grumpy on 40m, and
didn't tune down as far as on the other bands. From what I hear, that
is not unusual. But these changes have greatly improved how it tunes.
Thanks!

Joe the power meter in the K3 comes calibrated from the factory. If you
feel the need to calibrate it then you will need a fairly high

Wayne,
here's perhaps an idea: the K3 should load the memory as soon as you hit
M-V button, then
as you tune VFO-A it will load each memory number as you spin the VFO ...
This allows to receive on that memory as you spin it

Further to my last posting regarding the TX icon flashing all the time, I
