Could it be the AFX function is on? This adds a bit of delay between L
and R. In using a pair of non-amplified external speakers connected
to the rear SPKRS jack, I don't notice any objectionable echo when NR is
engaged. The setting which I use for SSB is NRmF5--1. This is mixed
audio being part original audio and part being DSP audio.

My K3S has sounded like that since I bought it.

Last year we upgraded one of the K3's with the installation of the
KIO3B interface kit. Shortly after we noticed that the NR sounded
different. Like an "echo", even on the least aggressive setting. The
NR performance appeared to have significantly suffered. Coincidence
with the KIO3B installation ? We put the K3 on the shelf and used the
backup K3 w/o the upgraded IO board. Two months ago we upgraded the
backup K3 with the KIO3B interface. Guess what, the same issue,the NR
reduction has suffered the same symptoms as the 1st K3 ! What is
going on here ? Tnx,73,Peter,HS0ZKX
