WIDTH control

Bruce Beford
I have this same discussion (which way to turn the width control) on a
regular basis.

Many people buy the variable-bandwidth NEScaf audio filter kit from the New
England QRP Club www.newenglandqrp.org and ask which way they should wire
the width pot. In those cases, I explain how the circuit works, and advise
them to wire the pot the way -they- want it to respond. You can have it get
narrower as you turn clockwise, if you wish.

On the K3, Bandwidth being the control label, it should -increase- the
bandwidth as you turn clockwise. So, I'm fine with the K3 response, as the
control actually does what it is labelled to do.

OK, so can we now re-open the discussion about which way the up/down band
buttons should work?  (just kidding...)
