Troubleshooting
Rows with ⚠, empty windows, packer shortfalls, scan files that will not parse, a plan replaced by mistake and plans that did not sync.
| Symptom | Likely cause & fix |
|---|---|
| A row shows ⚠ | The plan check found a problem on that row. Hover the ⚠ for the reason — too close, an intermod hit, or blocked spectrum. See The plan check. |
| Export asks This plan has n problems … Export it anyway? | The plan check found ⚠ rows. Cancel, fix them, export again — or export anyway if you know why. |
| Toast The plan already has intermod hits | + Add row or Coordinate cannot find a clean frequency next to a broken plan. Fix the ⚠ rows or press Recompute first. |
| Windows panel says Pick your hardware to see free windows | No band is selected. Pick a Manufacturer / Band, or import a scan. You can still print the regional whitespace. |
| No windows ≥ X MHz | Min width is higher than any gap in this band. Lower it, or zoom the spectrum to check whether the band sits in mobile spectrum. |
| Coordinate button is disabled | The packer needs a manufacturer band. Select one above. |
| Y requested, X placed — try a larger spacing | The band ran out of intermod-free room. Reduce N, change the Channel spacing or choose a band that reaches more usable spectrum. With several bands in the plan, the other bands' rows take room too. |
| Toast Band full when adding a row | Same cause — no clean room at the current spacing. |
| No clean backup left in this band | Every clean frequency in the band is taken. Lower the Backups count, or free room in the plan. |
| Toast Lost: … after Coordinate | The re-pack produced fewer slots than you have named rows; the names listed lost their row. Raise N and press Coordinate again. |
| Coordinating the IEM band moved my mics | It does not: re-coordinating a band re-packs only that band. Check which band is selected — the gear name under each talent says which band a row belongs to. |
| I cleared, loaded or imported over a plan by mistake | Press Undo in the toast — it puts the previous plan back exactly. |
| A window looks free, but there is a signal at the venue | FreqSense does not know which local TV transmitters are on air. Import a scan — see Import a scan. |
| A German band outside 400–960 MHz (174–230, 1350–1400, 1785–1805 MHz) is not on the spectrum | The spectrum covers 400–960 MHz. Those bands are listed in the regulatory table only; FreqSense does not coordinate them. |
| Scan import: no valid data points found | The file is not one of the supported formats. Save it as a plain two-column CSV (frequency in MHz, level in dBm) and retry. RF Explorer's binary file is not read — export CSV. |
| Scan import: many lines rejected | Wrong units or an odd header. The warning names the first bad line; check that frequencies are in MHz, kHz or Hz consistently. ; separators and decimal commas are fine. |
| Trace limit reached (3) | Remove a trace, or accept the prompt to replace the oldest. |
| Imported WWB/WSM plan: Format unrecognized | Set Force format to WWB or WSM. |
| Imported plan: fall outside the selected region's allocations | The plan was made for another country. Change Region first. |
| File too large (max 1 MB) | Remove unused columns or split the CSV. |
| Plan references scan "…" after loading a plan | Plans store which scan they used, not the data. Import the same scan file again. |
| Toast Saved plans are not synced right now | No connection, or the sync failed. The plans stay on this device and sync when the connection is back. |
| Plan saved on one device is missing on another | Both devices must be signed in to the same account and online. Reload — the toast Account data arrived means a newer copy has just come in. See Account sync. |
| Save failed — storage unavailable | The browser is blocking storage (private mode or full). Use a normal window or free up space. |
| Print view is missing the coordination table | Nothing was placed. Run Coordinate or add rows, then print again. |
Spectrum looks wrong for my country
Check Region / Regulatory Framework first — it is the single input everything else depends on. Spain has no region of its own: use EU and read Spain's row in the regulatory table. If the region is right and a band still looks wrong, open the Source linked for that band, compare it with the German write-up at /rf-cheatsheet/funkfrequenzen-deutschland (for DE) or your regulator's current order, and treat the regulator as the authority.
Thanks for the feedback.
