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
