NEC-LIST: Re: [Antenna Discussion] World Radio Noise Maps

A google search on - CCIR Report 322 1963

resulted in

& for question #2
Which I think may be found at the IEEE if you have a subscription.

I will add this to my list of stuff to download and share on my next
trip to the free public terminals at the local University, if nobody
else has direct access and wants to upload it to the files archive.

> Good day,
>
> I have a copy of CCIR Report 65 "Revision of Atmospheric
> Radio Noise Data", ITU, Geneva, 1957 which has maps of
> average noise contours for six time blocks and four season,
> and curves of average noise vs. frequency to go with them.
> A search of the web and a reading and search of the ITU web
> site indicates that the most recent such data is CCIR Report
> 322, from 1963, but this doesn't seem to be available
> anywhere. I did find an ITU Opinion that there are errors
> in 322 which ought to be fixed. Whatever their utility, I
> think a sample of these maps and curves has instructional
> value.
> 1. Is the data in 322 significantly different than the data
> in 65?
> 2. Is there an electronic version of these maps anywhere?
