[Elecraft] K2 Audio Filter

Sat Feb 23 13:06:03 2002

It appears that the sidetone frequency is pretty low.  I am used to a higher
tone in CW than what this is set to.  Once I found out where the "center"
was (which is fairly low) I then tried the AF and there was no volume drop.
Looks like I just have to adjust the side tone to a higher pitch...

I also noticed that the pitch changes a little when I go between some of the
filters, not alot, but noticable.   (Of course being a Musician, it drives
me nuts!! hehehe)

Thanks

Jason
