Feature Request: TX Watchdog Timer

Open ben-kuhn opened this issue 2 years ago • 3 comments

I occasionally run in to an issue where the TNC will get stuck in TX and need to be reset. I'm reasonably sure this is due to RFI somewhere, but I've never been able to track it down and no amount of ferrite beads help. It happens on my mobilinkd as well as several NucleoTNCs. The documentation suggesting ferrite beads on the cable between the radio and TNC suggest I'm not the first to see this. My current work-around is a TOT set on the radio, but the TNC still needs to be reset once entering this condition.

As a workaround, and for HT use, etc... where rf conditions may be out of the user's control, it would be a nice feature to have a user-configurable TX watchdog timer to reset the TNC after a user-defined period of time in TX--user defined so it doesn't mess with M17 voice QSOs.

Thanks for your consideration.

Does pressing the reset button on the TNC when it hits this condition stop the radio from transmitting?

Kind Regards,
