Bug Reports

Bug reports are always welcome. You can contact the author at ab0wv at arrl.net. Please include as much detail as possible, like settings in the Tools>Options screen, what you are trying to do, any relevant screenshots, and please include the files PinpointRawpacketsMMDDYYYY.txt and PinpointDebugLog.txt from your Documents folder since they may contain clues to what is going on. The point of providing this detailed information is that I must be able to reproduce the issue that you are encountering locally on my computer before I can attempt to resolve it. Thanks for your support!

Older Versions

If you run into an issue with a newer version of the software, feel free to download a previous version to see if the problem goes away. If you download an older version, please manually remove PinPoint APRS from your system first through Add/Remove Programs inside of Windows, before installing the older version. Then, please submit a bug report (see section above) to let me know what's wrong.

Beta Release Notes

April 9, 2026
This is a huge update, so lots of new features that need to be tested. PinPoint APRS was developed with the Amateur Radio Emergency Service (ARES) in mind, so I've spent time adding some features that help with additional situational awareness.
Here are the things that have been updated and added:
- First and foremost, please read the updated v2.2 Quick Start Guide to get more detail on some of the new features listed below.
- Added NexRad weather radar imagery. NexRad radar imagery is available from two sources: The National Weather Service (source: NWS) and Iowa State University's Environmental Mesonet (source: IEM). The default settings under Tools > Options > WX & Fire work well. It will select the closest radar to your location in PinPoint APRS, and use the hi-res NWS NexRad reflectivity feed. In the WX & Fire settings, you can override the default radar site to be used using the Single Radar Site option + dropdown list. The CONUS Mosaic option will show weather radar for the entire USA, but the resolution is not as great. If you want to use CONUS Mosaic, the IEM source is best.
- NWS Single Site settings under Tools > Options > WX & Fire(either automatic selection of closest radar site, or overriding with the dropdown list) will automatically support various NexRad radar modes where intervals between radar scans are shortened. These modes are often initiated during severe weather, and PinPoint APRS will update the radar imagery faster when available. If a NexRad radar enters SAILS mode, which increases the refresh rate of the NexRad radar data, PinPoint APRS will also start updating the Weather Warning polygons every 2 minutes (default is every 5 minutes). This feature is not available when using IEM.
- When using individual radar sites, right below the +/- for map zoom top left, you will see two buttons marked R & V, where you can quickly switch between Reflectivity radar product and the Velocity radar product, which is useful when trying to spot tornadoes and other weather events.
- Added a Weather and Wildfire warning/watches/advisories overlay with polygons showing affected areas on the map. Select the warnings / watches, etc you want to see by selecting the appropriate checkboxes under Tools > Options > WX & Fire. Polygons and data are updated every 5 minutes, except when an active NexRad radar goes into SAILS mode, accelerating updates to every 2 minutes.
- If you enable "Alert when I'm inside a warning area" in the WX & Fire setting, the map will show a red banner around it when your PinPoint APRS location is inside a weather warning area. The banner will clear once you move outside of the weather warning area, or when the warning expires or is canceled.
- Clicking on a weather warning, advisory, etc, on the map will give you more detail about the event.
- Added a Wildfire overlay with polygons (where available) to show wildfires and prescribed burns on the map. Wildfire are sometimes shown as polygons (when available) to show the fire perimeter, and sometimes as a round dot, where the size of the dot is commensurate with the size of the fire when polygons are not available. Clicking on a wildfire will give you more information about the fire. Polygons and data are updated every 5 minutes. Fires that are 100% contained show up a gray. Fires that are not 100% contained show up as red. Under Tools > Options > WX & Fire you can hide wildfires from the map that are 100% contained ("Show Active Wildfires Only").
- NexRad radar, Weather & Fire Warnings and Wildfire data all require Internet access. PinPoint APRS will still work fine without Internet access after maps have been cached, but you will not be able to use these new situational awareness features. - Your PinPoint APRS location must be in or near the USA for these new weather related features to work, since only USA-based NexRad, Weather & Fire Warnings and Wildfire data is being drawn on the map. PinPoint APRS will prevent you from using these features if your location on the map is outside the USA to reduce unnecessary strain on these public API's.
- When enabling the map scale, it now remembers the last setting at application start (show or hide).
- Fixed an issue where the map provider was sometimes changed when going into the Options menu.
- Updated credits to account for the additional data providers (NexRad, warnings, wildfires).
- Updated the 'save map to image' feature so it includes all additional data (NexRad, warnings, wildfires).
- Fixed a few typos.
- Fixed a bug in the compressed packet decode code related to altitude.
- Fixed an issue related to the direction (rotation) of the symbol on the map in compressed position packets with no course or heading.
- Cleaned up some fields in the Last Heard window that were being displayed when no value was available.
- SHIFT-Click-ing on the map now shows the "Add APRS Object" feature. This doesn't work yet since it's under active development. It's coming...
- Your own position on the map is now shown as the symbol you selected in Tools > Options > APRS, within a small yellow circle, rather than the green marker I used before. The mouseover now shows "My Position" and your call sign + SSID.
- Added an "Optimize' button under Tools > Options > Misc > Map cache info. Clicking this button will optimize the cache database on your computer, which can take up to a minute.
- Improved the GPX File import code. Made it more resilient against errors. Added support for GPX Routes (in addition to Tracks & Waypoints).
- Added support for KML/KMZ File imports.
- Added support for GeoJSON File imports.
- Pinpoint APRS now remembers the last GPS location you were in and resumes from there.
