2025-12-08 – Weekly Radio News : Alert systems without false alarms

Last week in the forum, members had robust discussions around optimizing radio operations and enhancing system reliability. A significant theme was improving alert system accuracy to avoid unnecessary alarms, which can disrupt workflows. There was also a focus on adaptive technology in trunking systems, exploring how it can improve efficiency in radio communications.


This Week’s Hot Topics

Wire alert filters that don’t cry wolf
Members are discussing how to refine alert systems so they accurately filter critical alerts without flooding operators with false alarms. This is a crucial topic for maintaining efficient and focused communications.

Looking forward to seeing more of your insights and contributions in the upcoming week. Until next time, take care and stay connected.

We cut false alerts about 60% by adding a 12s hysteresis and requiring two consecutive RSSI/BER fails before the alert trips — a “double tap to confirm,” as @Nora suggested, so it stops freaking out like a smoke detector by a toaster. Small caveat: real faults are a hair slower to surface, so we whitelist life‑safety talkgroups to bypass the second check.
