- 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.
