[Elecraft] Is there a reason the receive is so Skinny

The K3 receives perfectly well all the way to 4 KHz (200 - 4200,
100 - 4100, 50 - 4050 [if you can stand the growl]) as long as one has
a suitably wide roofing filter.  I regularly see 100 to 4100 Hz in data
modes using the FM roofer (I did not bother with a 6 KHz filter).  The 
response is easily dead flat for 3800 Hz with 4000 Hz at +1/-3 dB on
"Line Out" and slightly more on the headphone output with judicious
use of the RX EQ.

73,

Yes I know I can shift the center frequency, but by doing that the low end is diminished and I don’t like that either. Couldn’t this be done in a future DSP update. Just wishing.
