KG4YZY-10 APRS Digipeater & KG4YZY-11 I-Gate
Information
KG4YZY-10 is a Wide Area Digipeater for Pasco and
surrounding counties in West Central Florida. The KG4YZY-10 node digipeats only
Widen-N unproto paths as described in
Bob Bruninga's Fix 144.390MHz page
(the New n-N Paradigm as it's named).
KG4YZY-11 is an APRS I-Gate
that sends and receives on air APRS packets to and from the APRS Internet System (aprs-is).
The I-Gate, operating on the same antenna that the KG4YZY-10 digipeater does, covers
the greater Tampa Bay Area in West Central Florida.

The TNC and VHF transceiver powering this APRS node...
|
A Kantronics KPC-3
with version 9.1 of firmware is the terminal node controller.
This model is used heavily for APRS digipeaters.
KISS mode connects it to a server where
AGW Packet Engine Pro permits
TNC sharing.
|
A Kenwood
TM-271a
transceiver is the VHF 2 meter radio. This model is mil
spec, and has no fan to worry about. It produces 60 watts of spectrally
pure output. All connections to the TNC are done
internally on solder pads designed for TNC hookup.

228ft above sea level - 200ft above ground level on a commercial broadcast tower in
Port Richey, Florida. The site is located near the intersection of
US Highway 19 and Ridge Road in West Pasco County.

Tampa is a heavy APRS traffic area, you can see that with the load

Unproto path selection is simpler
in the New Paradigm. It does, however, mean that relay, wide, trace, tracen-N
are now obsolete unsupported paths.
If you are still using depreciated paths please
reconfigure your system's
unproto paths as suggested below, or none of your packets
will be digipeated:
These paths are suggested
for use by fixed location users:
wide1-1 - replaces old relay or single wide - gets digipeated once.
wide2-2 - replaces relay,wide or wide,wide - gets digipeated twice.
wide3-3 - the longest path supported - gets digipeated three times.
If you operate mobile using fill
in digipeaters these are your paths:
wide1-1 - replaces old relay or single wide - gets digipeated once.
wide1-1, wide2-1 - replaces relay,wide or wide,wide - digipeated twice.
wide1-1, wide2-2 - longest mobile path - gets digipeated three times.
