[aprssig] IS-to-RF alternate proposal - 'marked beacons'

YMMV but my Range 25 miles, -IS stations, maybe 15 (excluding CWOP) @ 
1/30 minutes.  -IS mobile stations, maybe 8 (max) @ 1/10 minutes, total 
-IS to RF IGating load: 40 every 30 minutes.  Current RF reception rate: 
5/minute up to 12/minute depending on propagation.

I personally have no plans to configure any -IS to RF gating parameters 
that would give a "good accumulated path" presentation over RF like the 
-IS users have come to desire/expect.  Just making their presence known 
is sufficient IMHO.

Other areas will have other loads and some areas may choose to gate NO 
stations from -IS to RF.  It's all dependent on the area's RF landscape 
and the desire of the IGate operator.
