Wireless system in use

Built-in table knows band ranges for common Sennheiser / Shure systems (no presets). The AI lookup uses web search to fetch the band range and factory preset frequencies, then plots them on the x-axis: clear / marginal / occupied judged against the current scan.

Uses the max-hold trace, so let it scan the band for a while first (walk the room/venue for best results). Checks the orders ticked below with the guard below.

Baseline (soundcheck)

No baseline yet. Let it scan for 30 s with the room as it'll be for the show — all your mics switched ON — then capture. Anything new after that gets flagged.

Recording

● REC records every sweep with a timestamp. ⚑ Event logs a moment instantly — if you're not recording it starts a session and keeps the 2 minutes before it, so you never miss the lead-up.

Reference field strengths

Source	Est. dBm

Free-space estimates at 600 MHz into a 0 dBi whip, line of sight, no cable loss. Real rooms vary ±10 dB — treat as rules of thumb. Edit in the REFS table in the source if you want your own numbers.

Equipment thresholds

Receiver	Usable from	Interferer trouble above

"Trouble above" = an unwanted signal on or next to your channel at this level will start squelching / dropping / muting that kind of receiver.
