Expected ambient noise

One of the casualties of the cessation of VK1OD.net was an article on expected ambient noise.

The original work was based on ITU-R P.372-8 which has been updated to -10 and now -12, but the updates do not alter the basis for the original article.

Since the work was a reference cited on my FSM pages, it has been updated and copied to Expected ambient noise level. The graphics and tables in the article and the PDF file all refer to ITU-R P.372-8 but remain correct wrt ITU-R P.372-12 (2015).
