Thanks Guy. I will wait your suggestion. I maked some different settings test but dont solved at the best. Working 90% CW, I tried different agc settings of agc thr and slp, but really I haven't found great solutions.I read some emails on reflectors about best agc settings, and tried them: THR - SLP12 - 510 -78 -2( I dont like higher THR settings, too noisy)OR5 - 12 (STANDARD ON k3S)7 - 1210-12But at the end I found that I prefer original 5 - 12  or the  little better 7 -12.I set agc hold that was 0 to 0,40 - it is better, it reduce noise between  cw letters, the K3S so seemed more as my old Cubic Astro 102BXA, that have a wonderful agc and a great qsk...But I understood also that thr-slp  5-12 is not the best for taking out of noise lower dx signals.So, really I havent found the ultimate setting...Also I am moderately satisfied of NR and totally unsatisfied of  NB.I confirm that I wouyld like your suggestions.73 de Ian IK4EWX

Have not forgotten this.  Have been sick for a while. It's on my reply list. 73, Guy

Many thanks Guy for you help. I use K3S from april and can be that I havent set at the best the rig.I work 90% CW, usually with 500hz 5 pole filter, sometime with the 200hz 6 pole.Usually I work 40-20-17-15-10 meter, in contests also 80 meters.In these last months I worked expecially 40-20-18-15.Usually I have AGC slow for ragchewing and fast for contests, always qsk with a bug.PRE - noATT-  no AGC - slow, sometime fastANT - a Force 12 C4 yagi (2el 20 - 3el 15 - 3 el 10m - 1 element 40m 17m 12m  - also have a dipole 80m-40m inv vee low on a roof at 5th floor; the yagi is 8m high from this roof (composite material, including aluminum layer), the buildings around are lower.RX ANT - noWIDTH - the same as xtal filter, 500hz or 200hz.
in the CONFIG MENU I have: AGC DCY - norAGC HLD - 0.00AGC PLS - norAGC SLP - 012AGC THR - 005AGC-F - 120AGC-S - 020
Now with the 500hz filter and agc fast, no preamp no attenuator,  ant yagi  to north america,  in this moment, I have this noise (local time 22.00):40m---- S7 20m ----S4 S517m --- S3 S415m -  S312 m --- S1 S228mhz--- S4Some time of the day noise from long range radar, wide spectrum military emissions or domestic applience or lights noises go up to S9.
You asked the higher signals that I receive: say 20dB over S9 or even 30dB over S9 from a pair of local hams at the other side of my town.
But I work all kind of signals low and high (327 countries DXCC and a lot of ragchew CW).
Thanks for your patience :)

Hi, Ian,

Can you possibly tell me these settings, please? You are getting
results very, very different than I do.

What bands are you using?

On each band in question, what is the noise floor on the s-meter when
the band is open.

On each band in question, what is the s-meter reading for the loudest
signals you are receiving when the band is open.

On each band in question, what are these settings made from the front
panel: PRE, ATT, AGC, ANT, RX ANT, WIDTH,

What are these settings made in the CONFIG MENU: AGC DCY, AGC HLD, AGC
PLS, AGC SLP, AGC THR, AGC-F, AGC-S

There is some kind of interaction with NB and NR for each of these.
Perhaps there are one or two of them that are reducing your results.

73, Guy K2AV
