KG4YZY-10 Digipeater & KG4YZY-11 I-Gate Coverage
This map, generated by
Radio Mobile, predicts the Longley-Rice
4/3 earth RF coverage of our 144.390 APRS Digipeater and
I-Gate at 200ft above ground level in Port Richey. Terrain is accounted for, such
as the ridge in East Pasco North thru Brooksville.
Scale is in dBm, in which
-100 is the worst, and -40 is the best signal on this map's scale.
Map assumes operator is mobile at high power (5ft high
AGL antenna). APRS, since it is a packet radio mode, requires full quieting to
fully decode the packets, so no less than -78.5dBm is required
for error free operation. Add 20-25% for a 30-50ft high outside
antenna, and remove 30-35% for HT 5 watt use inside a well built
structure. The voice repeater, on the other hand, is usable to -89.5dBm.
