Shortwave Challenge!

 
Here is another Challenge!
 
This time we explore the 9 MHz and 11 MHz spectrum between 1830 and 1900, which currently provide many opportunities for frequency usage analysis and propagation.
 
This challenge was on March 7, 2017, from Melbourne.

Shortwave Challenge!

 
Shortwave Challenge!
 
 
Very low levels of solar activity continue, meaning that the available "propagation windows" for frequencies above about 13 MHz have been compressed for long-haul multi-hop transmission paths crossing darkness or semi-darkness regions.
.
The challenge is to determine the optimum window for your location for the higher frequency bands!
 
Here in Melbourne, the 9 MHz band currently is "open" for the full 24 hours, yielding many chances for orderly analysis and research into frequency usage
 
This is a summary of notable occupancies between 2230 and 2300 on March 1, 2017.

MONITORING RESEARCH - 9 and 11 MHz

On the Boardwalk, near the monitoring site!
 
MONITORING RESEARCH - 9 and 11 MHz
 
This is a summary of notable frequency occupancies observed in the mid-afternoon, 0330 to 0400 on January 27, 2017, at one of my favourite field sites, in Westerfolds Park, at Templestowe, in Melbourne's outer east.
 
Receiver was the little Eton E5, with two metres of antenna. Some good E-mode propagation from Asia and Pacific apparent.

Spectrum Research - 9 MHz

 
SPECTRUM RESEARCH  - 9  MHz
Solar activity remains very low, according to the Department nt of Meteorology (Australian Government), with the 10.7 cm Solar Radio Flux at 84, and the Daily Equivalent Sunspot Number down to 26.
 
Those indices are expected;ected to drop even further in coming days.
 
This means that long-haul, mufti-hop propagation following darkness or semi-darkness paths on frequencies above about 14 MHz will continue to be unreliable.
 
Research of frequency usage in the 9 MHz region on January 24, 2017, revealed these notable occupancies, here in Melbourne, across the time span 1900 to 1930.

MONITORING RESEARCH 6 MHZ SPECTRUM

 
To all members and readers!
 
Here in Melbourne, our sunrise and sunset times have started to changed due to later sunrises and earlier sunsets. This altered pattern has resulted in variations in signal fade-in and fade-out timings, particularly on the 6, 7 and 9 MHz bands.
 
Propagation patterns have also changed, due to the continuing low level of Solar Activity, with the daily Equivalent Sunspot Number falling to as low as zero on some days!
 
This is a summary of notable frequency occupancies researched on January 9 2017,  across the time span 1930 to 2000.
