Every day, I monitor the FT8 frequency on 28 MHz and feed the spots up to the PSKReporter website. I don't have any real interest in making loads of contacts but I use the FT8 reports to follow the propagation and watch for unusual conditions.
On Tues 19th May 2020, I could see that the Sporadic-E skip was going short so I left the FT8 signals and concentrated on QRSS and WSPR signals instead. The map above shows the WSPR stations heard on 28 MHz over the space of maybe two hours.
What is interesting here are the signals from the UK with a skip distance as short as 400 kms on 28 MHz, a really intense opening. I also heard the GB3XMB beacon on CW which ties in with this.
What I find really amazing though are the stations running very low power on WSPR.
These are the stations I heard with less than 100 milliwatts....

As you can see, these range from 50 milliwatts all the way down to an amazing 5 milliwatts!
