Hello Rik, all...

The alert feature would be useful to me.

Ideal alert level to me would be new station *or* DX station (based
on distance). But if I have to pick on, then new station.

Alert via a pin on a serial port seems best, as long as it has the
possibility to work with some of the better USB to serial
converters. I have three sound cards, it's still not enough, they
are all busy. :)

73,
Paul N1BUG
