I wonder if we tried a PSK31 NET on a schedule we might discover some
marginal propagation that CW and SSB are missing?

OR ...

I am guessing that digital mode software can be set to beacon CQ's,
pause to listen, then auto-respond?

If that is correct then we could look at the saved log to see when the
propagation was open.
