Scott Tilley found Starshields transmitting in the wrong band over Canada and the US. I checked for these signals of the Starshield constellation, but received nothing at 2067.5 MHz. I switched from LHCP to RHCP at 14:53. They are not active over my place in the Netherlands.

Deep WALE (4G-ALE) async call using PSK2 (not MS-141D App.G compliant).Perhaps it is some specific implementation of a new and more robust Deep WALE call, given that PSK2 is more robust than PSK8.

I did set up my amateur radio station in our holiday home in Oreoi in Greece with the callsign SV1/DF3LZ. The Endfed antenna is working very good. Contacts to Japan, South Korea and USA were possible in CW and FT8. And at the end of the day dinner at the harbour. That's life!
