A solar eclipse is always a nice reason to experiment on the low bands. Especially 160m and 80m bands could be surprising when the solar eclipse is going on.
This solar eclipse will be on at Friday 20 March 2015. The local (Groningen) 84,7% solar eclipse begins at 09:33, maximum at 10:40 and ends at 11:51. All local time (UTC is -1 hour).
I understood that there will be activity on 160m WSPR from several stations in Iceland and Faroer Islands. It will be interesting to view how the solar eclipse is affecting the low bands. I will be QRV on 160m WSPR as well and invite everyone that has the ability to be QRV on 160m WSPR as well.
Update 20-3-2015: The solar eclipse has begun. So unfortunate I don't see activity anymore from TF4M on 160m since 6 UTC. It is nice to see the number of spots did decrease after sunrise. Now I expect to slowly get more spots when the eclipse evolves. I use my horizontal loop as endfed and 1W output power.
