Hi Mike,

I've fiddled with all of the AGC, PRE, ATT, RF, and DSP options on my K3,
and still experience a relatively high noise floor - at least compared to an
FT-1000 side by side.  

I never gave it much thought until these subject came up on the reflector.

Cheers,
James K2QI

G'day,

The simple fact is that the faithful will always suggest that the K3
hears more, is more sensitive or is more transparent to band noise
etc etc.  Also you have to fiddle with the AGC, PRE, ATT and RF gain
whereas other radios just sound nicer out of the box.  I don't have
a problem with fiddling with AGC and equaliser parameters to tailor
the receive to my liking, but to have to do it to make it sound
acceptable is another thing altogether.

There is an often referred to AF filter module which installs on the
main DSP board and apparently cuts out a lot of unnecessary high
frequency audio.  Sadly though often referred to it just isn't being
made available despite very positive comment from some of those who
have field tested it.

The KAF2 filter for the K2 made all the difference in the world to
listening to SSB.

Regards,

Mike VP8NO
