QSO?

What is a QSO nowadays? Not sure, in particular when talking QRSS.

The latest fashion seems to communicate via an online grabber. This this a QSO?
I don't think so, for the following reasons:

1. both stations have contact to the grabber, which is rather an automated SWL connected to the internet
2. there is no wireless link from the online grabber to neither of the two stations
3. the online grabber does not repeat a signal per se

However, all in all, I believe using a grabber to communicate is somewhat fun, since the communication is somewhat full-duplex.

What amateur radio is concerned, there still is the issue of dependency of many non-amateur communication channels, namely the ISPs of the three involved parties.
