QUICK DEMOS OF APRS
So you wanna know what this program does without reading all the README.files..
The following steps give the maximum exposure with the minimum of reading.
MARATHON EVENT: First, run APRS and use CTRL-L to load the MARTHON.BK file.
Hit SPACE to show the position of APRS packet stations at our marathon event.
Next do a REPLAY using Ctrl-R. Select the File MARTHON.HST. You will see
the LEADER and TAIL bicycles which were GPS equipped.
FOOTBALL RUN: To see the Army/Navy game football run from Annapolis to Philly,
load FBALL.BK, and hit PgUp for a 16 mile scale. REPLAY the FBALL.hst file.
Select only the station FBALL with Auto-centering on. To speed up replay, hit
F for Fast and W for WARP. The CHASE1 vehicle is also in the same file.
SPACE AX.25 DIGI's: See README.SAT for info on using APRS for plotting
satellite DX contacts and how to replay the SHUTTLE.HST demonstration.
CHANNEL MONITORNG: Zero memory with the Ctrl-Z. Tune your radio to an active
packet channel and monitor for 10 minutes. Select the LATEST display, and you
will see all UI frames (BEACONS) on the channel. If you know where these
stations are, insert them onto the map and save the file. Rename the file to
include the frequency for later recall. If no one is beaconing, and you get
impatient, you can turn off the beacon-Only filter by hitting the Alt-O
command. Then all packets will be gathered (but not NETROM stuff).
LOCAL AREA: To see our local APRS net, load the FREQ5-79.BK file. Zoom in to
my location and see my neighborhood streets. I drew that map using 1200 pixels
per degree. To see if your area is covered by an existing detail map, PgUp to
the USA map and hit the alt-M key. The outlines of all existing maps will be
shown. Move cursor to your area and zoom in (PgDwn) to within one of these
maps. To move long distances, CTRL-PgUp to large scale map, move to your area
and then Ctrl-PgDn. Have a friend place his LAT/LONG in his TNC BText as
follows: BText !DDMM.xxN/DDDmm.xxW/Comments... You will see him appear on
your map! Better yet, give him a copy of APRS and Add objects or station
locations to your screens by moving the cursor and using the alt-A command.
Similarly you may broadcast text back and forth by altering your BText using
the alt-B command or Send individual messages using S. Store your preferred
default map center LAT/LONG in the first line of the MAPLIST.map file, or save
a backup file with your station at the center. Reload this backup file each
time you start up to restore your screen and location. Better yet, register
your copy of APRS and get a validation number so you can save a config file.
OTHER IDEAS AND APPLICATIONS: See README.WX for using APRS in a weather
reporting net, README.DF for triangulation in fox hunting, and README.SAT
for displaying satellite beacons. Finally, read the full system documentation
in README.APR, and start drawing local maps as described in README.MAP. There
is a chess board map in the middle of the Gulf of Mexico at 25N 90W (below 64
mile scale) to show the flexibility of APRS to use any maps for any
application. Play chess on the air using APRS!
NOW WHAT?! APRS is a human communications tool. Try APRS during weekly
emergency exercises or events when humans are at their stations. Find a two
meter freq that is not saturated with BBS's and start an APRS network. In the
Wash/Balto area we are using 145.79. Please consider using this freq in your
area to help us build a nationwide mobile tracking network. Encourage periodic
reporting weather nodes (not the store-and-dump kind) and keyboard QSO's to
also join your frequency. Anyone with low duty cycle data is welcome, but
BBS's, file forwarding, NETROMS and databases should operate elsewhere! This
is NOT meant to be discriminatory, it just optimizes the frequency for the
maximum number of individual real-time users. This is best for all HAMS if
there is a frequency where human operators can communicate in real-time and not
only exchange text, but also see the instantaneous network topology.
