[Elecraft] K3 transmit and receive audio response

[amfmtv at aol.com]

Hello everyone,

I had a chance at Dayton this year to chat with the Elecraft honchos, 
and had every one of my K3 questions answered.  Thanks, gentlemen.

Meanwhile, a few hours ago, Wayne had written:

{While I'm on this topic, I'd also like to suggest using a minimum of 
both RX and TX EQ. The '0' levels were carefully determined 
empirically, and in most cases the optimal values will be well below 
the maximum range provided. Unless you have an aural sensitivity issue 
in some pitch range, or a serious mic deficiency, I'd stay between +/- 
6 dB. As with filter gain settings, excessive values can result in 
adverse interaction with the DSP.}

What I would like to know is just what the ACTUAL response curves of 
the K3 transmit and receive audio are (when all EQ settings are set to 
'0', since Wayne stated: "The '0' levels were carefully determined 
empirically."  It would appear from this statement that setting the 
EQ's to '0' wouldn't necessarily result in a 'flat' response.

I design parameters for some broadcast audio processors (Omnia's) 
and just am curious (and picky) what 'flat' actually is when the EQ's 
in the K3 are all set to '0'.  And,  for transmit, is the internal RF 
speech processor applied "pre" or "post" of the frequency response 
shaping circuitry? 

Thanks & 73.
