VK6BN, whoever you are, your station has great ears!

Here is a map showing all the WSPR stations this evening on 20 meters that could hear my station. If you’re unfamiliar with WSPR, it’s a group of amateur radio operators using K1JT’s MEPT_JT digital mode to probe radio frequency propagation conditions using very low power (QRP/QRPp) transmissions.
