Hooray! A new edition of rfax.pdf from NOAA!

I just noticed the existence of a newer edition (9 Feb 2011) of NOAA's HF fax guide. Because it took me ages to download it from their site, here is a copy of it!

E25 today on 9450 kHz


This is the 1230 UTC E25 transmission on 9450 kHz recorded in AM mode. The young lady has a variable rhythm. I suspect that the operators switched to Windows XP since there are reports of that particular OS sounds accidentally escaping to the airwaves. This may be the reason for the varying speech speed.

Nowadays there are more reports of E25 on 9450 kHz probably due to the improving HF conditions.
