[Elecraft] K3 Low end roll off in Data mode

[Dean]

I have noticed significant low end roll off in the Data mode below .5 kHz.
(Both transmit and receive). This is not present in the SSB mode. It is not
related to the settings on my roofing filters because it is there with both
the 6 kHz filter and the 2.7 kHz filter, and even with shift and width
settings set correctly for low end coverage.  It seems like it is the DSP
firmware.

 

This roll off can be limiting with some digital modes. Using SSB mode does a
great job of flattening out the lower end but it is very inconvenient to
have to zero out my equalizers each time I want to switch from voice to
digital.

 

Could somebody at Elecraft confirm if it is a firmware issue and if there is
a way to turn it off and make the Data lower end flat like SSB?

 

Thanks!
