[Elecraft] KX2 firmware suggestion

[Mike Penzo]

While in CW mode, I typically listen with the filter wide open (2.8khz). Once I find a signal, I narrow the filter down (400hz) by tapping the AF knob after tapping the FIL button. 

Opening up the filter (back to search mode) requires lots of cranking on the AF knob (back to 2.8khz) after tapping the FIL button. Wouldn’t it be nice if tapping the AF knob while in filter adjust mode would return the filter bandwidth to it’s previous setting (toggle between wide and narrow). 

Maybe there’s a way to quickly switch the filter BW back and forth (wide-narrow-wide) without having to crank the AF knob that I’m not aware? If not, seems like it would be an easy firmware update.
