SUMMARY.txt  Version 8.27

APRS works best at 9600 or 4800 baud.  See README.1st,  APRS.txt and HELP.txt.
and others. See MAPS.txt on making APRS maps.  The North American APRS Freq is
144.39 MHz and it is 144.80? in Europe.  Share your copy of APRS with others.

APRS monitors for  STATUS, POSIT, OBJECT, and MESSAGE  packets and accumulates
them on lists and the map.   APRS uses UI frames, on a decaying period so that
old data fades away.   The packet period doubles after each Xmission, decaying
to about 1 packet per 12 minutes after 15 minutes. The ToGo box shows the time 
to next transmission. APRS no longer Queries all stations on start-up.  If you
must get a refresh from everyone, use the XMIT-QUERY command.

Add objects on the map using the  cursor and INPUT-ADD.   Xmit 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 STATUS, BULLETINS AND MESSAGES on the  LIST-LOG page.   Posits
are saved on the Plist.  White objects are automatic, purple are manual yellow
are yours, blue are weather, cyan are dead reckoned and gray are old.   Posits
with a COURSE and SPEED are deadreckoned on receipt.  They show with an anchor
circle and the ICON shows where they should be in the elapsed time.  

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.
