[Elecraft] . K3 dvr playback distortion

[Don Wilhelm]

Geoff and all,

Currently, there is no way to bypass the equalization for the DVR.
When you record someone's off-the-air signal, it passes through your RX 
EQ settings, and then when you play it back, it goes through your TX EQ 
settings - so the audio gets hit with the "double whammy" of both RX EQ 
and TX EQ in a situation where you do not want any equalization at all.

If your EQ settings are all flat, then you can obtain and playback 
something that represents what you heard, but if you have either the RX 
or TX EQ settings adjusted for your ears, speaker, headphones, 
microphone, etc.  Then the individual whom you recorded will not be able 
to hear an honest assessment of how he sounded when you play it back 
over the air.

So yes, any "fix" will not be applied to the DVR, rather what is needed 
is the ability to turn off EQ when recording or transmitting previously 
recorded audio.  One would normally want to have the audio pass through 
TX EQ if it was recorded locally, but playback of recordings made off 
the air is different and needs EQ turned off.
