Where Does Universal Radio Hacker Store Projects?
URH keeps analyzed signals, protocols, and device configs in project files you save yourself. Autosaves guard crashes but projects are the archive.
Last updated
URH treats signals as documents. Captures, demodulator chains, decoded protocols, and fuzzing sessions persist in project files stored wherever you save them. Device settings for supported SDR hardware sit in the app config.
That file-per-project design makes folders the archive: one directory per investigation with captures, notes, and exports together. Exact paths may vary by version, so save explicitly instead of trusting autosaves. Label everything; mystery captures age into noise within weeks.
Where Universal Radio Hacker stores this, by platform
%userprofile%\Documents\URH\
Projects save where you choose; autosaves only guard crashes. Exact config paths may vary by version. Keep one folder per investigation with captures and notes.
~/Documents/URH/
Same project-file model as Windows. Device access may need group membership for SDR hardware. Save dated projects; unsaved work evaporates.
Frequently asked questions
How do I save analyzed signals?
Save the project after each analysis session with a dated name. Autosaves cover crashes, not organization. Demodulated protocols and labels live inside the project file, so unsaved work evaporates on close.
Why does my capture look garbled?
Match the sample rate to the signal bandwidth with headroom, then verify the SDR device string in the config. Dropped samples usually mean USB contention or an overambitious rate. Start wide, then narrow once the signal decodes.
