Hi Mal
630m band is much much more active than 600m at the moment
at least. All DLs of course, there hasn't been a night over
the last couple of weeks when I have not heard a CW Call or
QSO on or around 472.5. It may be like 600m at the start then
die out. The NDBs give a very good indication of band
conditions. Some of these stations are only 25Watts and I am
hearing stuff 400 to a 1000 miles out every night, but getting
the operating conditions for most is difficult, too bad it's
not published.
