Rik,
WE2XGR/6 is running at least 10dB more ERP than WE2XGR/3.
The limit for WE2XGR stations is 200 W ERP, and WE2XGR/6 (Bob W2ZM)
actually attains this when he runs full power though I believe that
Bob only runs about half that power on WSPR.
FYI WE2XGR/6 has been copied on ssb by Finbar - they even had a QSO
with Bob on ssb and Finbar using cw.
