Hi LF

I=20 am not stable enough, or is it the radio, to run WSPR15 on = 600m.

For=20 those stations that can / do it would not be easy to run WSPR2 and =
WSPR15 at=20 the same time, within those limits is anyone seriously
studying the=20 results.

Does WSPR15 really achieve anything that WSPR2 does=20 not?
