I would take a listen to a K3 on ssb mode and compare it to others
before deciding.
A flat RX equaliser setting sounds terrible with aggressive white noise
on my K3, using good quality headphones and/or ext speakers.
The pink noise roll off setting for RX equaliser as per ;
http://n1eu.com/K3/K3_notes.htmRed settings made the difference I can live with along with agc settings;
AGC THR = 8
AGC SLP = 2
AGC DCY = soft
AGC S = 15
AGC F = 80
AGC HLD = 0.2
AGC PLS = NOR
RX Equaliser (This is what really makes the difference to me)
50hz = +16 100hz = +6 200hz = +2 400hz = 0 800hz = -1 1600hz = -3
2400hz = -5 3200hz = -10
Using RF gain reduction to reduce noise against audio level is
beneficial until NR is required.
Also recommend the 1.8k 8 pole ssb filter with 1.6~1.8 k rx bandwidth
settings.
