What's New in HAMSignal
3.2
August 26, 2026
This update fixes a bug where the app's home screen could show a different grid square than the one you saved for your station location (QTH), making it look like your QTH wasn't saving. Your saved QTH is now shown correctly everywhere, including grey-line, propagation, and band alerts. Also in this release: - Numeric keyboards (frequency, coordinates, calculators) now have a Done button so they no longer block the field you're editing - Fixed several forms that silently rejected valid input on non-US keyboards - Clearer error messages when a form entry can't be saved - General stability and performance improvements
