[Elecraft] [K3] Another way to access APF

[Al Lorona]

There was recent discussion about the need to HOLD a pushbutton to turn on the 
APF. In January 2011, Wayne made a post entitled "Tips for using APF" in which 
he wrote,

"2. There are two filter "Presets" (I and II, accessed by HOLDing the  HI/WIDTH 
knob). You can turn APF on for one preset and off for the  
other. This control is closer to where the action is than DUAL PB, and  
I find it more convenient to use."

Although this still involves HOLDing a button it may provide a better 
alternative to the whole business of enabling APF.
