[aprs-fl] Fill digipeaters in the area

[Thomas A. Dye III, CCP]

Tom and Paul,

I have been saying for years that there are APRS coverage holes in the areas
of Dunedin and South West Palm Harbor, even for high powered mobile
stations.  Improving the network to allow coverage for 5w trackers would be
a very good idea.  This is a worthwhile discussion and I'm glad this list
has been revived.

I am interested in the 5 watt HT coverage for Pinellas county. It appears
you are using actual data versus path projections based on propagation
density. To reflect what a tracker was experiencing, you would have to have
a fully covered network and report the dbm of each received packet for
analysis. That would also assume we had a 5watt HT trying to get in that
actually did get digipeated.

Note, I think this is a fine network here and I am not denigrating it at
all.. I saw the same thing when I lived in Alexandria, VA - relatively close
to the birth place of APRS. It is just hard to get every nook and cranny
covered in packet systems with low height digipeaters (1000 feet and below).
I was just trying to ensure as close to full coverage for minimal power
trackers. I figure it will even help the area where my D710 running 50watts
does not get digipeated either (like the southern Pinellas beaches).

Thanks,

Tom NY4I

I have been generating APRS utilization graphs for quite some time now,
including state-wide Florida.  Look for *FLORIDA* and *PALMBAY* files at:
