Blindscan, FastScan, CableScan and other scan modules
Plugins extend Menu → Setup → Tuners, Scanning & Reception. Install them through the plugin browser/feed where available for your image. A menu entry alone does not make a frontend blindscan-capable.
Blindscan: discover unknown transponders
Section titled “Blindscan: discover unknown transponders”Blindscan searches a frequency and symbol-rate range. The driver or manufacturer-specific helper must support the tuner. Some reception paths, including certain SCR or FBC combinations, cannot use the same blindscan process. Follow restrictions reported by the plugin.
| Option | Meaning |
|---|---|
| Tuner / satellite | Select a configured reception path |
| Search type: channel scan | Search discovered carriers for services and save them |
| Search type: transponder scan | Display carriers and select transponders for further scanning |
| Start/stop frequency | Range in MHz; limits depend on Ku/C band and LOF |
| LNB inversion | For special LNBs whose LOF exceeds the reception frequency; distinct from normal scan inversion |
| Polarisation | H/V or L/R and combinations appropriate to the system |
| Start/stop symbol rate | MSym/s here; do not copy kSym/s numbers from manual scan blindly |
| Step size on supported devices | Smaller steps can be more thorough and take longer |
| Clear before scan / only free | Same basic decisions as for a normal scan |
| Only unknown transponders | Filter against the known satellite list |
| Disable sync with known transponders | Keep measured parameters without matching existing data; specialist use |
| Disable remove duplicates | Retain duplicate candidates; can clutter the results |
| Filter adjacent satellites | Exclude known carriers from neighbouring positions; requires useful reference lists |
The plugin writes results in satellites.xml format under /tmp; the result dialog shows the filename. This does not automatically replace the system list. /tmp is temporary: save wanted results before rebooting. Open XML displays existing results; Restore defaults changes plugin settings.

FastScan
Section titled “FastScan”FastScan reads prepared service/bouquet tables from supported satellite providers. Choose tuner, provider, HD list, FastScan numbering and FastScan channel names, plus a separate radio bouquet if wanted. Automatic FastScan and its provider selection control later updates. Without a matching provider transmission, it is not a universal shortcut for Astra/Hotbird.
CableScan
Section titled “CableScan”CableScan requires a supported cable provider and its initial frequency, symbol rate, modulation and Network ID. Official channel numbering, HD list and automatic CableScan control the generated list and updates. This differs from a normal DVB-C band search: a valid entry carrier for that network is required.
Other tools
Section titled “Other tools”Satfinder tunes a transponder and displays signal values; it does not replace a full scan. PositionerSetup additionally controls a motor. AutoBouquetsMaker generates provider bouquets. DAB+ Scan processes DAB ensembles. Regional plugins may add further methods; these are not installed on every receiver.
Frequency files such as satellites.xml, cables.xml and terrestrial.xml provide starting data. Preferred local files under /etc/tuxbox and packaged data under /usr/share depend on the image and installation layout; check the existing path or symlink. In contrast, lamedb/lamedb5 and userbouquet.* under /etc/enigma2 contain discovered services and their ordering. Do not substitute one type of file for the other.
