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?
