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.

How come we can transmit out to 4K but can only receive to about 3.5K. Seems
strange to me. I would like to hear as wide as I can transmit. 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.
