- SUMMARY.txt Version 6.7
-
- APRS works best at 9600 or 4800 baud. See README.1st, APRS.doc and HELP.txt.
- See MAPS.txt on making APRS maps. To aid APRS mobiles, try to use 145.79 MHz
- if available in your area. Share your copy of APRS with others.
-
- APRS monitors the channel for STATUS BEACONs, POSITS, OBJECTs, and APRS msgs.
- It accumulates a list of all stations and all BEACONS and places all positions
- on the map. APRS sends data as UI frames, using a decaying period so that old
- data fades away. The packet period doubles after each transmission, decaying
- to about 1 packet per 12 minutes after 15 minutes. The ToGo box shows the time
- to next transmission. On start-up with a newuser, APRS Queries a response from
- all stations. To Query just one station, use the XMIT-QUERY command.
-
- Add objects on the map using the cursor and INPUT-ADD. Xmit all packets at any
- time using the X key. Only BEACON, APRS, CQ, ID, SKYWRN and MAIL packets are
- processed unless you select OTHER. One line msgs can be sent to other stations
- using the S key. Use K to Kill incoming and E to Erase outgoing traffic. DF
- bearings (entered using INPUT-D) will show up as bright yellow lines. For a
- quick demo, use the FILE-LOAD and the FILE-REPLAY commands. See DEMOS.txt.
- Small yellow crosses mark map centers for maximum initial viewing size. You
- may toggle on/off the automatic loGing of BEACONS and POSITS to disk.
- ***** all times are in DATE-TIME-GROUP format (DAY-HOUR-MIN (DDHHMM) ******
-
- APRS stores new BCNS in the ALL list in sequence and maintains a LATEST list.
- Posits are saved in the Plist. White objects are automatic, purple are manual
- yellow are yours, blue are weather, cyan are dead reckoned and gray are old.
- APRS not only plots mobiles with GPS/LORAN interfaced to their TNC, but also
- displays manual posits. The position of a vehicle entered by one station will
- be displayed and dead reckoned on all screens until the next update. You can
- disable DR'ing if desired. This tracking is ideal for public service events!
-
- APRS is ideal for SKYWARN, DX and DFing. WX stations show up blue with wind
- speed/direction. Other WX symbols can show severe WX conditions. For auto-
- matic WX reporting, use the ULTIMETER-II WXstation option. See README\WX.txt.
- APRS can display automatic Doppler DF bearings. See DF.txt. APRS will map DX
- spots from DX clusters. See DX.txt. Use J key to show Just one symbol type
- at a time. APRS is ideal for DX if stations put GridSQ's or LAT/LONG in their
- BTexts. You can configure APRS for SAREX and Mscatter. See SPACE.txt and
- other ideas in README files! For program validation info, hit F1(HELP)-V.
-
- Use V to VIEW all packets or R to READ mail. Use the OPS-COMM-TNC command to
- use your TNC in dumb terminal mode, but with APRS processing disabled.
