There is some debate over QRP and declining solar activity. Certainly more power helps when conditions are marginal although often if a path is open then a few watts are fine for a QSO. At present, I use 5W maximum and most times 2W yet still seem to get spotted around the world on WSPR and JT 2-way modes. As I have mentioned before, even at the rock bottom of earlier solar cycles I have still worked LU (over 11000km) on QRP SSB on 10m with very modest wire antennas. No, more power may help with a pile-up but even QRP is fine if the band is open. Of course, summertime Es generally needs only QRP. I have worked Es DX on 6m with QRP and a helical whip on the FT817. Es can be great fun.
