[Elecraft] KAF2

[Kevin Rock]

I have been using my KAF2 more and more recently but find I only use the AF2 setting.  I am contemplating installing the jumper to eliminate the AF1 setting.  I was 
wondering what others think about this?  Am I going to lose some capability of which I know little when I perform this jumper installation?  Do others use the AF1 
setting for certain instances I have never encountered?  I am enjoying the audio filter more and more as I use CW on 20 meters.  I have found during the daytime 
that 20 meters is much more consistent if I use the AF2 setting.  I can copy down to the noise floor.  All of you K2 owners out there you know how far down the noise 
floor is :)  Sometimes I don't think I am hearing anything at all but the letters keep appearing at the end of my pencil.  Some sort of magic is driving it.  Must be K2 
magic :)
