Unable to reproduce on macOS Mojave and node v8.15.0. Any clues on how to trigger the bug?

brannondorsey commented 5 years ago

This bug was triggered after leaving the chattervox chat functionality open for an extended period of time, and presumably receiving a non-chattervox packet like APRS. My guess is that this could be triggered by tuning your radio to 144.39 (the APRS frequency in the US) and receiving normal APRS traffic for some time.

I've got a fix inbound ;)
