[Elecraft] K3 Audio Response - Version 3.33 Firmware

[David Lankshear]

I spent much of the evening browsing AM shortwave stations and can confirm
that the additional bass lift capability in 3.33 can be used to give a much
warmer sound.  I reduced the first couple of equaliser bands to +3dB and
with the full bandwidth possible with a 13kHz filter, a slight shift below
the FC Norm of 1.5 gives much warmer audio.  I did find that adjustment
varied depending on the voice being listened to in order to get the most
satisfying result.  In all cases, I did not go below the 1.05 setting to
achieve the most satisfactory sound with most being around the 1.30 mark.

 

Similar results were heard with SSB, and brought the K3 into line with good
sound from my K2 and a comms Rx, both of which rendered a warmer audio than
the K3 prior to beta 3.33.  Many thanks, Elecraft.
