What next?

 As I mentioned in an earlier post today, 630m WSPR seems to have "gone off the boil" and I may try something new over the spring and summer. 

I want to try 8m QRPP WSPR using 10mW and ISM rules (open to anyone in the UK without a licence, possibly in your area of the world too?).  This is mainly a daylight challenge.

Is there a new nighttime challenge? A band that remains good at night. Possibly 160m or 80m using the earth-electrode "antenna" in the ground? I could try FT8 on these bands perhaps.
