Virtual SDR
Tune a receiver — set a center frequency and bandwidth, and whatever signals live in that window get captured, at their real place in the spectrum.
Open the tunerPoint it at a band. See what's there.
Every emitter sits where it really lives — on its own broadcast dial, channel raster or allocated band. Where you tune decides what ends up in the capture, the same way it would on real hardware.
Tune to a band and you get what populates it — a site with its repeaters, a dial of stations, a constellation overhead — each emitter on its own channel and its own schedule. The band fills itself.
In-band signals land at their correct offset and anything outside the window is rejected, with no aliasing artifacts. Add the impairments real hardware brings — carrier and clock offset, phase noise, IQ imbalance, DC bias.
Capture raw IQ (float32/64, WAV, SigMF, MATLAB, VITA49) or a spectrogram of the tuned window — the same output formats as the dataset generator.
Tune, then capture.
-
1
Set the bandwidth and tune the dial
Drag or scroll across the spectrum, or jump straight to a band — the window highlights whatever falls inside it.
-
2
Choose what's on the air
Include or exclude each in-band channel and set how many emitters populate it. Open a channel to fine-tune its parameters.
-
3
Pick an output format
Raw IQ for a pipeline, or a spectrogram image of the tuned window.
-
4
Capture the window
Download the slice of spectrum you tuned to — in-band emitters summed at their offsets, everything else rejected.
