[Elecraft] K3 vs. HPSDR Mercury receiver

[Alan Bloom]

One way to get better-sounding audio, both on transmit and receive, is
to use a wider-bandwidth crystal filter and let the DSP do most of the
filtering.  Because the digital filter is linear-phase it will sound
much more natural than an analog non-linear-phase filter.

That's why I leave ESSB enabled all the time on transmit, with the
bandwidth set for minimum.
