Installation Notes

APRS is distributed on a single 3.5 inch HD disk with these files:

  INSTALL.TXT  - This file
  PKUNZIP.exe  - For unzipping APRS (omitted from some disks to make room)  - ALL major files.  Builds 6 subdirectories:
                 MAPS - Holds all MAPS     
                 HSTS - History files      SYSTEM - APRS system files
                 BAKS - BACKUP files       README - all README files
                 LOGS - LOG directory      MAPLISTS - all maplists  - Regional maps  - East maps
                          - North East maps
                           - Midwest maps
                           - Central Maps
                           - West Maps
                          - S.East maps

APRS will run on any 8088 through 486 PC with CGA,EGA, or VGA. BUT NEEDS ALMOST 540 K of free memory. You may have to remove TSR's or reduce the requirements of your CONFIG.sys. APRSMIN.EXE will run with only 411K. APRS will NOT work with non standard video cards, for example, the Hercules Video card. You may make this work marginally by running the readily available SIMCGA P program first to make it simulate a real CGA device.

--------------------------------------------  --------------------------------
1.  Create APRS directory on your Harddrive-  MD APRS
2.  Change Directory into that directory   -  CD APRS
3.  Put APRS disk into A and change to A   -  A:      (or B:)
    Do Pkunzip with directories:           -  PKUNZIP -d  APRSvv.ZIP  C:
4.  Get the maps for your area             -  PKUNZIP -d  Xmapsvv.ZIP C:
    (where X is your region, E,NEA,M,C,SE or W)
5.  Execute APRSxxx                        -  APRSxxx
    a. Give your call and other info as prompted.
    a+ Use MAPS-CHANGE to select your EAS,NEA,MID,CEN,WES or SE
    b. Move cursor to your exact QTH using arrow keys and PgDn (shft-PgDN)
    c. Hit INPUT-MY-POS command and answer QTH questions
    d. Use UNPROTO command to set your VIA Digipeater path (needs TNC)
    e. Move and center map to your area of interest and preferred range scale
    f. Save a config file using alt-S-SAVE  (repeat steps e - g at anytime)
    g. Provide your Validation # when requested during the SAVE command.
       (APRS will only ask for the V#'s for your present configuration.)
    h. WRITE DOWN YOUR V#'s on your wall.  Don't lose them!
6.  Troubleshooting tips.  READ TROUBLE.HTM!
    a. Verify COMMS with TNC using the OPS-COMM-TNC command.
    b. For AEA or KANTRONICS, set EXPert ON or INTFACE TERMINAL in order 
       for the TNC to respond to some APRS commands
    a. For convenience, you may RENAME the .EXE file to APRS.EXE.  You can
       always find the Version # on the F1-LOGO or HELP screen.
    b. APRS has two command line options:  
       *  APRSxx /b will execute APRS AND load the last BACKUP file
       *  APRSxx /xyz will execute APRS from an alternate config file .xyz
          see 5f above.
    c. You may customize the TNC commands INITIALIZED and RESTORED by APRS
       in the files named InitTAPR.TNC, InitAEA.TNC and RESTORE.TNC.
       Add commands or use the * to REM out any unused lines. BE CAREFUL,
       APRS will NOT work unless all the parameters are correct for ur TNC.

My distro disk contains the big USA maps and your regional maps. You must check with your local BBS or APRS friends for your own STATE maps. Look for where XX is your state abbreviation, and VV is the latest Version number. See MAPS.HTM for info on additional maps, and MAPMAKIN.HTM on how to make maps or to customize your file to your area.

THE LATEST APRS is posted on the TAPR.ORG FTP site in the /tapr/SIG/aprssig /files/upload directory along with a file similar to which will contain only the files that changed since the earlier release. Come join the aprssig on the INTERNET! See for details

************ REMEMBER TO USE PKUNZIP -d ***********

UPGRADES: If you are unzipping an upgraded copy of APRS, or any of the XMAPS.ZIP files, you can use the command PKUNZIP -dn and only NEW files will be unzipped into your APRS directories... Also READ NEWNOTES.HTM to see what has changed!

FOR A LIST OF INTERNET and other phone line BBS's known to carry APRS, and more state maps, see the last paragraph of the READMEREADME.1st file. It also announces the APRSsig on the Internet for exchange of ideas on APRS! See also DOWNLOAD.HTM file too.

See my web page: FTP the latest APRS: in tapr/SIG/aprssig/files/dosstuff/APRSdos


If you want to zoom into other areas of the country, not included on your distro disk, simply download and PKUNZIP -d some of the other map.ZIP files, and use the MAPS-CHANGE command to temporarily load the MAPLIST appropriate to the new maps. Then just zoom in and maps will automatically appear.

MINIMUM SYSTEMS: Despite the 3 Mbyte size of the whole APRS system, a minimum system can be built in under 500K with only the .EXE,, at least one .MAP file, and all SYSTEM files. All directories must be at least created even if empty. You can also delete the SYSTEM*.POS files.

RUNNING ON A and B FLOPPY-ONLY SYSTEMS: Build a Boot-System disk, copy only APRSxx.EXE onto that disk. Put that in the A: drive. On another disk put as much APRS as you need. Put ALL of the SYSTEM directory there, Make MAPS and MAPLISTS directories and put at least the MAPLIST.USA and USA.MAP files there (add others as you have room). Then at least create the LOGS,HSTS,POS,README directories. Now Boot up on the A drive, Change default drive to B:. Then RUN APRSxx from B: with the command A:APRSxx. APRS will then use the B: drive as the default and run just fine.

DISTRO ON TWO 720K FLOPPIES: I do NOT do this, but it is easy for YOU to split the APRS distro disk for sharing with others on TWO-720K disks as follows:

  1) MD ATEMP                           (make a temporary directory)
  2) PKunzip MAPS*.* ATEMP (Unzip just the USA MAPS there)
  4) PKZIP -d  MAPS*.*    (DELETE all USA maps from this ZIP)
  5) PKZIP ATEMP*.*        (Zip up all the maps into
  6) Now copy, about 650K onto one disk
         Copy and your regional XmapsYY.ZIP onto the other....
  7) The 720K user then uses PKUNZIP -d on the APRS and Xmaps files
     then he changes into his MAPS directory and does a regular PKUNZIP
     of the file.
