Install the exact EZ Scan edition and preserve the current SD-card configuration.
Whistler publishes separate EZ Scan downloads for each TRX model and region. Open the edition that matches the scanner, read or copy its current configuration first and keep an archive before adding any new objects.
Important: Do not choose an import action that replaces the whole SD-card configuration. Add the rows as conventional objects, assign them to a deliberate scan list and review that list before writing.
Import the three columns, assign a scan list and write the updated configuration.
- 1
Open the matching EZ Scan edition
Confirm the title identifies the correct TRX model. If you use a UK-market TRX-1E or TRX-2E, use its international EZ Scan download rather than another model's edition.
- 2
Load and archive the current configuration
Connect the scanner in its SD-card or mass-storage workflow, or insert its SD card in the computer. Read the current configuration and save a separate archive before editing.
- 3
Start a conventional text import
Open Conventional Frequencies and use EZ Scan's text-import function. Select the supplied ScanLocal .txt file rather than trying to copy it directly onto the SD card.
- 4
Map the supplied columns
Treat row one as headings and map Alpha Tag to the object name, Frequency to receive frequency and Mode to receive mode. The file uses decimal MHz and clean 16-character alpha tags.
- 5
Choose a scan list
Assign the imported conventional objects to a new or clearly named scan list. Confirm that the list is enabled and is included in any Scan Set you normally use.
- 6
Review the conventional AUTO objects
Every selected assignment is supplied once as a conventional object with Mode set to AUTO. ScanLocal does not create separate DMR, NXDN or P25 trial copies. Same-frequency rows can still represent separate licence assignments, so compare their names before removing anything.
- 7
Write through EZ Scan
Use EZ Scan's Scanner/SD Card workflow to copy the updated configuration to the correct scanner or card. Wait for completion, then eject the storage safely before restarting the receiver.
- 8
Confirm DG Mode Auto and test
On the scanner, browse the imported objects, open the object menu and confirm DG Mode is set to Auto. Start scanning with the new scan list enabled, then keep, skip or refine entries as listening evidence develops.
Check the imported objects, scan-list assignment and written SD card.
Alpha tags appear as names, frequencies display as decimal MHz and each imported object shows AUTO rather than shifted header text.
Every imported object belongs to the intended scan list, and that scan list is enabled in the active Scan Set.
EZ Scan finishes writing without an SD-card error and the receiver can browse the new conventional objects after restart.
Restore your backup: Return the original card unchanged where possible, or restore the dated EZ Scan archive to the correct scanner or replacement card. Never restore a configuration made for a different TRX model.
If EZ Scan imports no rows or the scanner says there is nothing to scan.
The columns are shifted
Repeat the import with comma separation, use row one as headings and map Alpha Tag, Frequency and Mode explicitly. Do not resave the text file through a spreadsheet first.
Nothing to scan
Confirm the new objects are assigned to a scan list, that the scan list is enabled and that the active Scan Set includes it.
The SD card is not recognised
Stop writing, use the saved configuration backup and check the card or USB mass-storage connection through the matching EZ Scan edition before trying again.
An AUTO object remains silent
Confirm DG Mode is Auto on the scanner and that the object is active in the chosen scan list. Some assignments may be inactive, encrypted, unsupported or part of a trunked system that needs site and talkgroup data not present in WTR.
A compact conventional import that preserves separate public assignments.
The file has a UTF-8 marker, Windows-style line endings and exactly three columns: Alpha Tag, Frequency and Mode. Alpha tags are cleaned to 16 characters and every selected assignment becomes one conventional AUTO object, with no protocol-driven duplicates.
Separate licence assignments are preserved even when their frequencies match. The list is for conventional discovery and does not supply talkgroups, a complete trunked-system definition or guaranteed protocol and access-code data.

Questions
Is this a complete EZ Scan configuration?
No. It is a conventional-frequency import that you add to a backed-up configuration and assign to your own scan list.
Why can the same frequency appear more than once?
Matching frequencies can belong to separate licence holders, sites or digital uses. Review the alpha tags before deciding whether two objects are redundant for your own listening.
Why are the imported objects set to AUTO?
AUTO keeps the Whistler file compact and avoids guessing DMR, NXDN or P25. Confirm DG Mode is Auto after import so analogue, digital, mode-not-stated and data/other tuning leads remain available without implying that every signal can be decoded.
Does the file program trunked systems?
No. It contains conventional objects only and does not create sites, talkgroups or a complete trunked-radio system.
When were the official software links checked?
The Whistler downloads, FAQ and product-guide links were checked 11 August 2026.
