Gregory's Server@niconiconi It indeed makes an interesting read!
Not so sure about its universal utility, though. Legal base is local.
And the #hamradio service is special in it does not operate by any fixed written standard. It continuously adjusts its own procedures, informally.
E.g., by the RR book, "CQ QRP" would mean "all stations, please lower your transmit power". In the #hamradio service, it has come to mean: "I am seeking a contact with any low-power station."
Nothing wrong with that.
@niconiconi For what it is worth: At the German Hamradio fair, I have been in a presentation yesterday of the ENAMS project. It has distributed some 50 or 60 stations, most of them in Germany, that continuously measure radio background noise data. It wants to establish what the present state is, compared to the data published as recommendation ITU-R P.372-12 (07/2015) "Radio noise". I understand the latter is mostly based on measurements some 50 years old.
