[Elecraft] [K3} [KX3] SSBT like CWT ?

[Gary Gregory]

Eric,

I have the K3 and KX3 sounding pretty close in the headset on RX. (CM-500)

I have found that adjustment of the RX-EQ needs to be done first and then I
set the Hi/Lo cut and I then went and rechecked my RX-EQ settings to be
sure I had the best audio for me. By doing it this way I now rarely find
the need to adjust my Hi/Lo cut again unless the band is acting
dramatically different to when I did my set up or a station has moved close
to the frequency I am operating on and I still need to work the frequency I
have been on. Obviously I have no need to alter my RX-EQ settings now that
I have them set.

My ears are not good, the internal speaker on both rigs don't work well for
me. Tinnitus IS an issue that I can't get rid off short of
decapitation...:-)

As I don't hear the lows very well, I have changed the RX-EQ to improve the
audio quality and I check that against the Hi/Lo settings I prefer so that
now I rarely have a need to change them.

Tuning up and down the band for me now is pretty easy with respect to
hearing a 'pleasant' tone of voice.

YMMV of course and my opinion must be taken as purely subjective and I hope
you don't have to deal with the difficulties I have to deal with on a daily
basis.
