Track HF band openings and view the propagation paths to Queensland Australia
WSPR technology is well suited to reporting of weak signal strengths (below the noise floor).
The following charts show received spots reported by VK4EMM located in Queensland Australia. The charts show unique spots from six continents over a 24 hour period. These charts are useful to indicate when bands are open and closed.

Real-time analysis
An advanced site for collection and analysis of real-time data is produced by Phil VK7JJ – Highly recommended. Phil’s website is located at http://wspr.rocks/
At another level, Phil’s charts help transmitting stations see their signal strengths as received from any distance at any time of day.
