[Elecraft] Yaesu YH77STA & K2

Hi Vic;

You can build a roll off filter with some caps and an inductor or two. Look
at an old "ARRL Handbook" for this info. I'm not sure if the newer Handbooks
cover this topic.

The trouble with these is that they are monaural.  Stereo is important
because I want to investigate binaural modes for CW, such as putting the
I and Q outputs of a quadrature sampling detector into each ear, etc.

The Yaesu phones are stereo but the frequency range is important so I
can get rid of the external DSP I'm using to kill sidetone thumps and
clicks.
