Maybe some screenshots explain it better:

DL1EMA starts with dB(m) so he wanted a value that could be "measured" and not be guessed.

Yes Yes
... only the right noise Level was interesting for the first timeThank you for all answers

Take the NBTP floor as S0 (ca -127dB) and then the CW beacon has abt S5+3dB.
Strong stations have a signal about S6.
Everything above is unwanted and to much uplink power.
The strongest HAM station i saw till now had S7+3dB. (SSB)
BTW, Forget the S-Meters on the WEB-SDRs they are all wrong.

OK I will check... why -127 is over 30MHz then -147????
-
Perhaps we should use the Beacon level as S9 as this is equal to a solid SBB signal than.. everyone like to have an S9 Signal
That is good...

I will calibrate my S-Meter on SDR-Radio...
What is right on QO-100:
-73dBm = S9 (like this goes up to 30MHz)
-93dBm = S9 (like this goes from 30MHz)
How is the noise level defined?
On the Web-SDR (eshail.batc.org.uk) the noise level goes to S6.
The most OM`s are S9+, I think that is not right... or???
I know the signal to noise is right.
What are yoo doing?

Hallo Michael,
so sehen jetzt die Leiterplatten aus, wenn Diese mit einer Dampfphasenlötanlage gelötet sind.
Herzlichen Dank an meiner Kollegin (Simone) für den guten Einsatz.
Testen muss jetzt nur noch Michael, die LP`s werden heute versendet.
