- NOTES: The 1700 mile vacation trip over XMAS was a blast. Stations all over
- the country reported tracking us on the HF freqs below. Just in one week, the
- number of APRS stations on the HF net doubled to about 2 dozen! Use the Alt-R
- command to Replay the XMAS93.HST and the 93BLOCK1.HST files to see how well HF
- can be used for tracking! Here are a few of the really active centers of APRS
- activity: Maryland, S.NJ, Boston, SanFrancisco, and Columbus OH.
-
- RV AND MOBILE HF NET: We have begun a nation wide Boat, RV and APRS position
- reporting net on HF using 7.085 and 10.151 MHz LSB. (Yes this is in the band!
- 10.151 MHz - 1700 Hz audio modulation is 10.149.3 RF energy. This is the same
- frequency as saying 10.147.6 USB, but the convention on HF is to specify packet
- frequencies using the LSB convention to be compatible with everyone else on the
- band) If you run an AEA or other TNC that uses 2210 HZ instead of 1700 Hz
- center tones, then tune 510 Hz higher on LSB and lower on USB. We are trying
- to get the WaterWay net to start using APRS on 10.151, so its time to start
- looking for a playing freq on 20 meters for new users that just want to play.
-
- BBS ADDRESS: My BBS address is WB4APR @ WB3V.MD. I cannot respond to tons of
- traffic, but will try to keep up... Do feel free to send me any comments o
- r suggestions. Similarly, I would like to add your return BBS address to my
- database in case I have to send out any erratta info on the APRS program.
-
-
- START HERE!!!: You should read all of the following README files on the disk:
-
- README.1st - This file
- README.NOW - Tells you how to unzip the APRS distribution disk
- README.NEW - Tells of important changes in the latest versions
-
- README.APR - General description and overview of APRS
- README.BBS - Suggestions to BBS SYSOPS on how to use APRS
- README.DF - Information on DFing and the new V 3.0 Doppler interface!
- README.DIG - Using DIGITIZERS to draw your own maps with MAPFIX.bas prgm!
- README.DUM - Info on APRS formats so you can use DUMb terminals and TNCs
- README.GPS - Interfacing a Magellian or Motorola GPS to a stand-alone TNC
- README.HF - Notes on the APRS HF tracking network
- README.HLP - Describes each of the APRS commands in detail
- README.MAP - Detailed information on how to build your own maps
- README.MCM - Lessons learned at the Marine Corps Marathon
- README.OPS - Suggestions on routine APRS operations
- README.QIK - A quick summary of demonstrations and replays to impress you.
- README.RPT - A discussion on ways to use digipeaters to extend an APRS net
- README.SAT - Suggested use of APRS for plotting satellite packet stationns
- README.SYM - A table of APRS symbols and the symbol designator
- README.TNC - My thoughts on how TNC code should support APRS
- README.WX - Info on using APRS for displaying weather information
- README.WWN - Suggested use of APRS to support the WaterWay Net
-
- Next you should customize APRS to automatically come up centered on your
- favorite map screen. If you are a registered user, first use the V command to
- validate your callsign. Once this is done, the yellow control panel will show
- the VALID box. Now set up the map to your center of activity. Either your
- home, or a WIDE area APRS digipeater. Next set your desired digipeater path
- using the Ctrl-V VIA command. Finally, use ALT-C to save your configuration.
- From then on, APRS will always come up ready to go on your chosen map area.
-
- Non-registered users can force APRS to default to their favorite map area and
- scale instead of the USA by simply using a DOS text editor to set the Lat/
- Long/Range in the first three lines of the MAPLIST.MAP file to their selected
- area. Without a config file, APRS defaults to this area and all you have to
- do is place your QTH on the map with the insert key, and you are ready to go.
- Of course save the original center USA coordinates so that when you give out
- copies of APRS to others, they will have the whole US map to start with.
-
- MAPS! - I will try to generate "starter" maps for regions where there is APRS
- interest. These "starter" maps give you an initial structure for adding more
- detail. They have a rough state outline and maybe an interstate or two, just
- to give you a starting point. It is really quite simple to draw a map. Using
- just a state Highway map, it should only take you an evening to enter all of
- the interstate roads and the important four-lanes; and another evening if you
- have to do a lot of detail coast line or rivers. Fortunately, everyone in the
- state can use the results of your efforts! I find that with just the inter-
- state highways and the important four-lane roads, you have a perfectly useable
- map for most VHF packet operations. You only need to draw more detail maps
- for special events or applications.
-
- PACKET POSITIONS ON ALL FREQS: Finally, encourage all BBS's, NODES, Servers,
- and stations in your area, to start placing their LAT/LONG in their beacon text
- using the format: BT !DDMM.xxN/DDDMM.xxW/....comments. As of version 2.05,
- APRS will also plot the positions of stations reporting by Grid Square
- surrounded by brackets [FM19xy]. And as of version 2.08, the !LAT/LONG can be
- anywhere in the BText. This permits TheNET Nodes to add it to the end of their
- ID Beacons. If all packet stations get in that habit, then APRS will
- automatically plot a map of packet activity on any frequency!
-
- FLASH! Just learned that all PACCOM TNC's with version 3.1 firmware include
- a GPS ON command! This command tells the TNC to look on the serial port for
- GPS data (NMEA-0183 format) and take the GPS position information and place it
- in the TNC BText. Then the TNC will transmit that Position every time it
- sends a BText. Now anyone with ANY GPS and a PACCOM TNC can go GPS mobile!
-
- MORE READING: For more info on APRS, see page 92 of July and page 11 of the
- August QST and the Dec issue of CQ. Also see the front page of the May issue
- of the AMSAT journal (but the registration information is incorrect there).
