At 0854z I went on 15m FT8 with 2.5W and the tiny indoor loop.
So far (0935z), 8 RX spots. It is a dreadful day outside: cold and rainy.
I get the feeling 15m is only just open today. I have seen far better days.
UPDATE 1322z: 9 spots of my 2.5W QRP FT8 so far.
UPDATE 1526z: 16 spots of my 2.5W with the furthermost K1CA (5246km). On RX 156 stations spotted with the furthermost YB3LZ (12245km).
UPDATE 1925z: 26 spots of my 2.5W to the indoor loop antenna today on 15m FT8 TX.
