[aprssig] APRS QSO frequency

[Bill Vodall WA7NWP]

> Yes, it will be really nice when there are enough people putting their true-real-time operating frequency in their position reports so that people will actually begin to trust that if you call the person on their "position report published frequency" that they will actually be there!

Maybe this could be extended to include the "Live Operator" bit even
for home stations.  On the other hand, is this a good thing to show
the operating frequency of a station when there's no operator.
