Notes

Speakers in Firefox: if you pick headphones or speakers other than your computer's default, your own CW sidetone may be slightly delayed. Station audio isn't affected.
Safari: audio plays through whatever output your Mac, iPhone or iPad is set to use. To change it, use your system's sound settings or Control Center.
iPhone and iPad: no setup wizard is needed. You'll be asked for microphone access the first time you connect. LocalMate runs only on a Mac or Windows computer, so WSJT-X and N1MM+ aren't available on iPhone or iPad.
For every feature: use Chrome, Microsoft Edge, or Firefox.

The browsers are untested, and some functionality may not work:

If you are using LocalMate, we provide releases for the following operating systems:
