[Elecraft] [K3] K3 Rev C DSP with Low Freq Enhancement ship date info; New swap out option on parts order page. CORRECTION

[David Lankshear]

May I ask why the LF response improvement was confined to headphones only? 

Why was the improvement not applied to all audio outputs, or am I missing something here?

Grateful thanks.  DaveL  G3TJP

The hardware mods improve the *TX* audio path low frequency response from all 
three sources (front microphone, rear microphone, line in).  They also improve 
the Rx low frequency response for *headphones* only.  Lined out and speaker 
low frequency responses are not affected.
