[Elecraft] P3: Span control logic

Kenwood?  On the TS-930  clockwise is widest in CW, counter clockwise narrows.  
In this case I think it is just as logical to state that,  just as I reduce the 
volume by going counterclockwise I also reduce the bandwidth by going 
counterclockwise.

Neither way is right or wrong it is just a learned preference.

I open my own jars and my first radios only had barn door wide for bandwidth.

No, no, no...every filter control I've ever used (until the K3) narrowed the filter bandwidth as the knob was rotated clockwise.  Hallicrafters, Collins, Kenwood, etc.  That's the one control I am still having trouble with on the K3.  It is bass-ackward from anything else.  Heck, when I put a lid on a jar, I turn it clockwise to screw it down tighter -- like tightening the bandwidth.

Of course, if you're too young to have used any other radio gear, or if your mother always opened the jars for you, I can understand why you might feel as you do.
