[Elecraft] K3 K3DSPUPG note

[Lyle Johnson]

Please contact Elecraft support.

As the designer of the DSP code, and of the DSP board itself, including 
the latest, I am 100% certain that Rx EQ 1 and 2 function no differently 
in the new board.  Further, if you are using headphones, the the 
increase of coupling capacitor from 10 uF to 100 uF earlier this year 
improved the LF response on receive.  The new LPF board is DC-coupled in 
the signal path, so it has no reduction of LF response, either.
