NB IF NAR/CODEC

Mike K4PI
I have 2 K3 and a K3S and for some time I have noticed all 3 doing something that seems incorrect.  All the radios are all up to correct Rev levels.  For years with my normal local noise, I always ran the NB at IF Nar 1-4 most all the time with good success.  In recent months, maybe more, on Nar only when I get up to NAR 1-4 to 1-7 more noise than what I am trying to remove appears ie with no NB and S4 with some minor local line noise, at NB Nar 1-7 the noise is S6 or more.  I don’t see that on any Med and Wide.  I don’t see any difference in what band I am on but on the higher bands I have PRE 1 on.  Any input from others that might have seen this is appreciated.  I know in past years this did not occur and I have been lax in asking the question.

I see I received some criticism in regard the question on CODEC.  Someone said ask “what did I do last”.  Well the time program was set to 1 sec many months before I used the program that indicated there was some sort of problem and it was noticed as soon as I started using the K3S.  I was only looking for some input and not blaming the K3S but since it was in the equation with the computer I had to ask.  Receiving input like that I think make some not want to even ask any legitimate questions on the forum. I did receive a lot of good info and that was much appreciated.  73 Mike
