PROPAGATION RESEARCH 9 MHZ

 
PROPAGATION RESEARCH 9 MHZ
 
Solar Activity has fallen considerably, with the 10.7 cm Solar Radio Flux now down to 71 and the Daily Equivalent Sunspot Number has dropped to an extraordinary low of 6, according to the Dept. of Meteorology in Sydney. Dept also advised that these levels are expected to drop even further in the days ahead, as we move through Sunspot Cycle 24.
 
This means that the frequency window of propagation opportunity has contracted, and will continue to do so, with reliable, long-haul multi-hop transmission over darkness or semi-darkness paths now limited to below approximately 10 MHz.
 
Here in Melbourne, good propagation continues in the 9 MHz spectrum during our winter daytime period, and this summary of frequency occupancies was made on July 4, 2017, late-morning, between 0100 and 0130, just prior to Solar Noon.
