We’ve been busy with updates! Lots of improvements and more to come, notably Internationalization!
As always if you find any bugs or have any suggestions or comments, we welcome those in our Groups.IO, Discord and Facebook channels.

GridTracker v1.22.1008 is now available for download.

This release addresses numerous issues from our issue tracker and further enhances POTA hunting, and now reporting.

Most importantly we are welcoming the GridTracker creator, Tag Loomis N0TTL back into the development team. He had stepped away to take some personal time and we’re glad he’s back. Tag has also been active again on FT8 mostly on 20m, he shouldn’t be hard to miss with his “star” in the call roster so do give him a call if he scrolls across your roster.


Main App:

  • New option in Settings -> Lookups -> Feature Control -> POTA. When “Enabled”, track POTA spots from pota.app and auto-report activations. When “Menu Button” checked and menu button active, show active parks following “Map View Filters” rules.
  • OAMS spotting fixed for multiple-instances
  • St. Maarten continent changed from SA to NA
  • DXCC none ( ie: CALL/MM ) no longer counted in Scores or DXCCs stats tabs
  • After long window minimize, restore looks correct.
  • Fixed dupe check for last QSO partner (chasing bands, not logging)
  • Prefixes and direct callsign updates from BIGCTY 2022-09-20

Call Roster:

  • Fixed right-click on DXCC not showing DXCC ignore menu
  • Fixed “Clear Call Roster On Band Change” bug that caused the roster to blank
  • Fixed Age column not sorting correctly
  • Fixed County cell not doing lookups when allowed
  • Changed County column to show number of potential counties for a callsign
  • Add “RR73 as CQ” to Exceptions
  • Added 4 new “Masters of Radio Communications” awards from QRZ.com to Award Tracker
  • Award Tracker now shows in the Wanted cell the first award that meets criteria
  • Instances now horizontal between controls and roster table
  • New option in Settings -> Call Roster -> “Call Roster Delay On Focus”.. when enabled will delay redraw of roster after decode round(s)

Happy New Year

It’s been a busy holiday season with the GridTracker team, a couple of us are settling into new jobs, one of us moved to a new state. And we’ve been working on old bugs and new features as well. We’ll continue to work on those with testing on some changes currently ongoing. The plan is to release a version before Spring.

What started as one hams way to not get buried in highlighters and printed off gridquare maps 4 years ago has evolved into the hamshack companion for operators of all kinds, we still track grids, but also now DXCCs, states, counties, CQ Zones, ITU Zones, WPX, various other awards, we have filtering and sorting that’ll make it much less intimidating for operating on today’s very crowded digital sub-bands.

So to celebrate as we’re testing all the new features and bug fixes we’re working on from February 1st through the 14th, members of the development and test teams will be signing with special event callsigns. Afterwords we’ll collect all the log files and prepare a nice certificate to email out to anyone that worked us.

The best part is that we’re going to make a lot of fun QSOs with everyone which to me is one of the best aspects of amateur radio!

Release of GridTracker v1.21.0928

The GridTracker team is excited to announce the release of GridTracker v1.21.0928 with a couple of bug-fixes and the availability of packages now for 64 bit ARM architectures.

ARM builds now use NWJS 0.54.2 which introduced support for 64 bit ARM processors and OSs. Until now, we were using the 32 bit version on 32 bit OSs with 64 bit hardware. There could be performance improvements with using 64 bit software on 64 bit hardware.

Bug fixes include a fix for malformed ADIF records when special characters where included in the record. That has been fixed and the length counting of the record should be correct and allow the entire record to be sent including the full “<EOR>” tag at the end.

The other bug fix is further improvement to doing differential downloads from LoTW, we look at the ADIF headers provided by LoTW and save a “last fetch” date-time stamp to use to refer to pull records only since the last check. That code has been simplified for reliability.

You can find GridTracker v1.21.0928 in the Downloads page.
