[Elecraft] K3 question to those who have upgraded their DSP board

The LPF affects PHONES (fropnt and rear) and SPEAKER only.  It does not affect 
LINE OUT.

The component value changes improve headphone out (front and rear) low 
frequency response by changing the 10 uF output coupling capacitors to 100 uF. 
 LINE OUT is not affected by this change, nor is speaker out.

Tx Audio low frequency response is improved for all external Tx audio sources 
(front Mic, rear Mic, LINE IN) by several componenet value changes.

The componenet value changes for Tx audio and headphone audio were 
incorporated in production radios several months ago.
