Plus a minimum-voltage readout that speaks punch-out sag while I am still flying.Part 8: Four Things Wrong With Ithttps://itohi.com/fpv/edgetx-cockpit-voice-whats-wrong/Sun, 16 Aug 2026 16:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-whats-wrong/ Stacked thresholds that layer sirens, zero debounce against punch-out sag, an alarm that fires before the first telemetry frame arrives, and the link-quality warning I never wired up.Part 7: Two Antennas, Two Bands, and the Quad I Lost to Polarisationhttps://itohi.com/fpv/edgetx-cockpit-voice-antennas/Sun, 16 Aug 2026 15:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-antennas/ ELRS control-link antennas are linearly polarised, not circular like video. Why one horizontal and one vertical on a true diversity receiver beats a single antenna, and why my telemetry already measures it.Part 6: Telemetry Logging, and the One Number You Have to Measure Yourselfhttps://itohi.com/fpv/edgetx-cockpit-voice-telemetry-rates/Sun, 16 Aug 2026 14:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-telemetry-rates/ ELRS telemetry ratio, CRSF frame round-robin and the EdgeTX log period sit in series. Why the arithmetic is not the answer, how to get the real per-sensor rate out of your own CSV, and the 3D viewer I built to read it.Part 5: Where the Callouts Come From, and Why You Cannot Just Copy My Confighttps://itohi.com/fpv/edgetx-cockpit-voice-audio-and-sharing/Sun, 16 Aug 2026 13:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-audio-and-sharing/ The callouts come from the stock EdgeTX voice pack, not from anything I recorded. What to scrub from a model YAML before publishing it, and the positional sensor-index trap that makes a shared config misbehave silently.Part 4: What the Radio Actually Sayshttps://itohi.com/fpv/edgetx-cockpit-voice-callouts/Sun, 16 Aug 2026 12:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-callouts/ The battery ladder, the satellite callouts, and an altitude alarm that fires on change rather than absolute height. Including the self-test I like most and the delta function I did not plan.Part 3: Three Buttons, Three Colours, and the AND Gate That Ties Them Togetherhttps://itohi.com/fpv/edgetx-cockpit-voice-buttons/Sun, 16 Aug 2026 11:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-buttons/ How EdgeTX customisable function switches, an RGB colour per subsystem, and one AND slot per logical switch turn eleven threshold detectors into three things you can switch on and off.Part 2: The Calibration Every Battery Warning Rests Onhttps://itohi.com/fpv/edgetx-cockpit-voice-calibration/Sun, 16 Aug 2026 10:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-calibration/ A miscalibrated voltage reading does not look broken, it looks plausible. Why report_cell_voltage makes a vbat_scale error propagate twice, and what the 3S-to-4S move does to your alarms.Giving My Quad a Cockpit Voice, Part 1: Why a Drone Should Talk to Youhttps://itohi.com/fpv/edgetx-cockpit-voice-why/Sun, 16 Aug 2026 09:00:00 +0300https://itohi.com/fpv/edgetx-cockpit-voice-why/ A low-battery number in the corner of the OSD is an interface failure, not a pilot failure. Why I made my RadioMaster GX12 speak, and the one flight-controller setting the whole thing depends on.
