June general update

The June general update v1.21.0620 is now available on the downloads page. This update contains a more permanent fix for downloading logs from ARRL’s Logbook Of The World (LoTW) that doesn’t require GridTracker to pull down the entire log. GridTracker did several versions ago pulled down only what we thought were changes since the last time logs were downloaded, however there were reports that QSOs and QSLs were missing so we went to pulling down the entire log which did insure we didn’t miss any QSOs or QSLs that had changed but put an additional load on the LoTW servers. Last week we disabled automatic loading of LoTW logs on startup to alleviate that load and allow other logging programs to sync on startup. Now with the improved code in v1.210620 we have re-enabled loading of LoTW logs at startup but we only pull the changes since the last time logs were downloaded reducing the load on the LoTW severs further. This version also implements a cool-down timer that doesn’t allow logs to be downloaded from the LoTW servers within 5-minutes of the last download.

We want to thank everyone that has contributed and that has been a lot of you. Your contributions are a great help in maintaining this website and the Off-Air Message Service (OAMS) servers. We made a change in how we update the file in GridTracker that contains the list of our contributors so now once a day GridTracker pings us and get’s an updated list (except when in off-line mode).

We are already thinking of what to put in our next update which wont’ be until July because who wants to download new software during ARRL Field Day this next weekend! If you have any comments, suggestions, ideas or constructive criticisms, you can drop us a note in our Groups.IO email group, in our Discord server or in GitLab.

Speaking of ARRL Field Day, we’re looking forward to getting on the air this weekend as we’re sure most of you are. If you are using GridTracker at your Field Day setup, take a photo and share it on social media (which counts as Field Day bonus points) and include the hash tags #ARRLFD and #GridTrackerFD.

Hotfix v1.21.0613

A hotfix release v1.21.0613 was released tonight to address an issue where when launching GridTracker and other logging programs that all try to sync their LoTW logs at the same time, the LoTW download abuse mechanism is triggered causing errors. This is a temporary fix where we’ve disabled automatic downloading of LoTW logs at start-up. LoTW logs can still be downloaded by clicking the LoTW icon in the control panel. The long term fix is in the works and should also speed up the time it takes to pull down LoTW logs.

This new version of GridTracker can be downloaded here.


This is our May 2021 general release including several bug fixes and a few new features and updates.

Due to the high volume of GridTracker users that were polling for spot data on the PSK Reporter servers, GridTracker was blocked from accessing data. The team worked with the operators of PSK Reporter to make changes to GridTracker to reduce the load we impose on their system and this version includes those changes. To restore PSK Reporter spots users need to upgrade to this version of GridTracker.

We want to thank everyone that contributes to GridTracker. Starting now if you donate to GridTracker and provide your call sign we’ll add you to the list in the next version. Then when your call sign will receive a special recognition icon next to it when is displayed within the program. If you’ve contributed to us in the past and want to be included, send an email with your call sign to ‘[email protected]’.

The latest version of GridTracker can be downloaded here.

UPDATE: We’ve found a bug that prevents log loading in the new version. We’ve pulled down the links to the new version for now and will update when we have it fixed. Thanks to everyone that found and reported the issue to us. We’re working away at it right now.

We know it’s been a while since the last version of GridTracker. But the wait is now over. There’s been a few changes not only with what’s in GridTraker but also with how we’re developing, fixing, and packaging GridTracker, while maintaining the purpose and vision that Tag N0TTL started out with. He’s still around and throwing little bits at the project, peering over the shoulders of the development team and taking time to himself as needed. A rest he well deserves for his hard work the past three years.

This is the first official open source release of GridTracker. It contains a number of bug fixes and a handful of new features.

Stephen ‘Tag’ Loomis has graciously made GridTracker open source. That means we can all work together to make it better. ‘Tag’ has decided to spend more time focusing on other projects, but there is a new core team of developers who are working to keep things current and continue on his great work.
