EXCELLENT PROPAGATION ON 11 MHz

 
EXCELLENT PROPAGATION ON 11 MHz
 
Did you know that Australia is a BIG COUNTRY? HF reception conditions vary significantly across our "Land of Sweeping Plains", even within the same city or town!
 
Here in suburban Melbourne, propagation continues to be excellent on those bands which are "open", consistent with prevailing ionospheric conditions.
 
The pre-sunrise window is good, with solid signals from 90 through to 22 metres. The 49, 41, 31, 25 and 22 mbs are dominated by darkness-mode transmissions from Europe, Africa, Middle East and Asia.
 
This is a summary of key occupancies found on Sep 1 2015 in the window  1830 to 1900.

Of technical interest –
 
* VOA's Amharic service from Woofferton, Thailand and Kuwait, pushing in from the east and north
* Kirundi services from VOA-Vatican (SMG) and BBC-Yerevan simultaneously
* Time-shifted (30 mins) transmissions of VOK resulting from the introduction of new local times there

TUNING IN TO THE 31 METRE BAND

 
TUNING IN TO THE 31 METRE BAND
 
Propagation in to Melbourne on 9 MHz continues to be very good in our post-sunrise period.
 
Solar activity continues remains very low – the 10.7 cm Solar Radio Flux has dropped to 85, and the ESSN has fallen to 27.
 
This summary of spectrum occupancy between 2030 and 2100 on August 30 2015 shows observed channel usage across the lower area of the band, up to 9565.

MONITORING RESEARCH - 11 MHZ SPECTRUM

 
MONITORING RESEARCH - 11 MHZ SPECTRUM
 
Low levels of Solar Activity continue, causing unreliable propagation on frequencies above about 12 MHz on long-haul multi-hop paths across darkness or semi-darkness zones.
 
IPS (SYDNEY) REPORT of Aug 26 -  Solar activity was Low over the last 24 hours with region 2403 (S14W27) producing numerous C-class events flares, the largest being a C4.3 event at 0631. Region 2403 remains relatively unchanged in size and in magnetic complexity with the potential for further M-class events and possible X-class. Solar wind speed ranged between 400 km/s to 450 km/s over the UT day while Bz ranged fluctuated between +2nT and -5nT. An equatorial positioned coronal hole has moved into a geo-effective position with an anticipated arrival of its high speed solar wind stream on Aug 27 to early Aug 28. Solar activity is expected to be Low to Moderate over the next three days.

The 9  MHz band is represented by high occupancy during the evening period in Europe, the Middle East and Africa – this summary shows usage monitored here in Melbourne on August 2152015 across the 1830-1900 time span.
 
Of special interest:
 
- Broadcasts in Kirundi, to Africa, from the BBC (Yerevan relay) and VOA (Vatican Radio relay), both observed 1830-1900!
- Bible Voice Broadcasting from Nauen
