Propagation and Monitoring - good Asian signals on 11 MHz

Sunspot activity continues to be ZERO, and the sun remains blank of sunspots (at least on the visible disk).

It's reported that there appears to be a new region that has formed high in latitude in the southern hemisphere.

Unfortunatly this region is rotating out of view and it's not known if there is a sunspot unless it survives the rotation around the hidden side of the sun.

So, Cycle 24 has still not started, and is not liklelt to so any time soon!

Although sunspots themselves produce only minor effects on solar emissions, the magnetic activity that accompanies the sunspots can produce dramatic changes in the ultraviolet and soft x-ray emission levels. These changes over the solar cycle have important consequences for the Earth's upper atmosphere.

See this NASA site for interesting information:

http://solarscience.msfc.nasa.gov/SunspotCycle.shtml

MSFC Solar Physics Branch members at the Marshall Space Flight Centre have studied the sunspot record for characteristic behavior that might help in predicting future sunspot activity. Current predictions of solar activity for the next few years can be found at

Despite the lack of sunspots, the ionosphere continues to work very well for long-distance propagation on frequencies above about 12 MHz for daylight transmission paths.

Reliable propagation over darkness, or semi-darkness paths, is confined to frequencies below about 12 MHz - here in Melbourne, the 3, 5, 6, 7, 9, and 11 MHz bands continue to be very good during the various propagation windows which appear during any 24 hour period.

We are very close to the September Equinox - after that, we will begin to experience the summer daytime propagation phenomena from Asia and Africa in the bands below 12 MHz.

Melbourne reception on 11 MHz is scintillating in our evening window, centred around 0930, with some interesting occupancies for broadcasters in Europe making increased use of relays in Asia and the Far East, at times when direct shortpath propagation is not posssible.

Some occupancies noted in the 0930 to 1000 window include:

11565 TAIWAN WYFR-Taipei Mandarin
11580 MARIANAS KFBS-Saipan Mandarin
11620 CHINA CRI-Xian, English
11675 SINGAPORE Croatian Radio, Kranji, Croatian
11700 PHILIPPINES RFE-Tinang, Russian
11735 N. KOREA R. Pyongyang, Korean
11740 SINGAPORE NHK-Kranji, Japanese
11765 USA KNLS Alaska, Mandarin
11780 CHINA CNR8, Minority Langs network, Uighur
11825 PHILIPPINES VOA-Tinang, Mandarin
11865 N. KOREA VOK, Japanese
11875 TAIWAN RFI-Tainan, Mandarin
11905 CHINA CNR6, Taiwan Network, Hakka
11965 THAILAND VOA-Udorn, Mandarin
