UI-View (16 bit) Downloads

UI-View v2.39 (not intended for XP and newer) is a single file for doing a full installation. uisfx239.exe (1.86MB).

If you want to be able to put the installation files on two floppies so you can transfer them to another PC, then download ui239_1.exe (1.38MB) and ui239_2.exe (475KB) instead and run each of them with an empty formatted floppy in A: drive and they will create disk 1 and disk 2 of a two floppy disk installation set.

If you are using the 16 bit UI-View v2.32 or later, you can update it to v2.39 with  u16up239.exe (1.03MB). If you are using a version of UI-View earlier than v2.38 with AGWPE, you should install this update. Unless there is a reason to use the older 16 bit version, choose UI-View32 v2.03 below.

UI-View32 v2.03 Downloads

UI-View32 cannot be used without a registration.

If you are in the USA or Canada, and want to use UI-View32 with Precision Mapping, then see the UI-View32 and Precision Mapping page for information about what you need to download. PMapServer9 allows use of Precision Mapping version 9 from UnderTow Software. You can still /download PMapServer. A few screenshots can be viewed here on this site.

V2.03 is the latest full installation of UI-View32. It is supplied as a single file, self-extracting installer 32full203.exe (5.02MB).

UI-View32 V2.03 Update - If you already have a previous version of UI-View32 installed, this self-extracting installation system can be used to update UI-View32 V1.80 or later to V2.03 - 32upd203.exe (2.52MB). See CHANGES.TXT for details of all the changes that have been made since V1.80.

NOTES: UI-View32 was written before Windows Vista, Windows 7, or Windows 8 were on the horizon. Versions of Windows newer than XP use UAC... User Access Control. The operating system doesn't like programs writing to files below Program Files. UI-View saves settings in the file uiview32.ini any time you make changes, and of course the station lists are always changing. For this reason, UI-View32 should be installed somewhere other than below Program Files for versions of Windows newer than XP.

Operating systems newer than XP do not support .hlp help files. The context sensitive help built into UI-View really helps set it apart from other APRS clients. If you are using anything newer than XP but older than Windows 10, you should download WinHlp32.exe from Microsoft's site. Unfortunately, it won't work on Windows 10, but there is a solution. Download RestoreWinhelp32.exe from Stephen WA8LMF's site. It is based on work by Komeil Bahmanpour.

  • Please note that RELAY, WIDE and TRACEn-n are now obsolete in North America. The big problem with them is that they cause a horrendous number of dupes. The "ping pong" effect of the dupes does more harm to the APRS network than paths that were too long.
  • The new "universal" path is WIDE2-2. Fill-in digipeaters that used to respond to RELAY should change their alias to WIDE1-1. Where mobiles need the help of a "fill-in" digipeater, they should a path of WIDE1-1,WIDE2-1 instead of WIDE2-2. Even if they happen to be in an area where the fill-in digis haven't yet changed to WIDE1-1, this path will still be compatible with all of the WIDEn-n digis in the rest of the network.
  • There may be occasions where a station needs a longer path, but many smart digipeaters are "trapping" excessively long paths. Do your part to help fix the APRS network by helping to spread the word, as well as changing your own trackers to WIDE2-2 or WIDE1-1,WIDE2-1.
• NWAPRS - supporting APRS in the "Pacific Northwest" but lots of good information concerning configuring TNC based digipeaters with the "new paradigm" settings for WIDEn-n "wide" digipeaters and for WIDE1-1 "home fill-in" digipeaters.
• TinyTrak 3 and PocketTracker www.byonics.com
• OpenTRAC Open Tactical Reporting and Communications is a message protocol designed for carrying tactical information, including GPS position reports, weather data, and telemetry, over an unreliable, bandwidth-constrained network. Typically, this is the Amateur 2-meter VHF band using 1200 bps AFSK. The protocol is specifically designed, however, for use across multiple networks to support Internet backbones, satellite links, and so on. Time will tell if this is an "APRS replacement" or if it will be a parallel network.
• OpenTracker is an APRS and OpenTRAC capable GPS and telemetry encoder, physically and electrically compatible with the Byonics TinyTrak3. The device connects to a GPS receiver and radio, and transmits AX.25 packets at 1200 or 300 baud. The firmware is published under the BSD license.
• Xastir APRS client designed to run on several platforms including Linux & Windows.
