SDR--Patch a radio together
Wire a receiver to a channel, the channel to a speaker, a map or a recorder. On your desk, or on a server at the antenna.
macOS, Windows, Linux. Free and open source.
Every flow is a wire
A Device node feeds channels. Channels feed speakers, maps, logs and recorders. Nothing happens behind your back.
Choose what the signal becomes
A channel turns IQ into sound, messages, pictures or a recording.

- @david3rd X The first SDR that works in an intuitive way. I stopped using SDR software because they all failed to work properly.
- Muhammed Mustaqim YouTube This NEW SDR Software Is AMAZING!
- YouTube viewer YouTube This is probably the best software so far. Thank you.
- YouTube viewer YouTube So it's what GNU Radio should have been.
- @david3rd X Light years more capable and is also flow graph based.
- j2T-QkTx38_atdg72G r/sdr I'm pretty new to the sdr world and been looking for a main workhorse as far as software goes, and I think this might be it!
- Reddit user r/RTLSDR Hell yes this is exactly what I've been wanting!

Plug in a radio. Start patching.
The app runs its own server. Or run the server alone by the antenna and open it from any browser.
brew install newspicel/tap/sdrminusminus
or the server
brew install newspicel/tap/sdrmm
brew services start sdrmm winget install Newspicel.SDRminusminus
curl -fsSL https://newspicel.github.io/packages/key.gpg \ | sudo tee /usr/share/keyrings/sdrminusminus.gpg > /dev/null echo "deb [signed-by=/usr/share/keyrings/sdrminusminus.gpg] \ https://newspicel.github.io/packages/deb stable main" \ | sudo tee /etc/apt/sources.list.d/sdrminusminus.list sudo apt update sudo apt install sdrminusminus
sudo dnf config-manager addrepo \ --from-repofile=https://newspicel.github.io/packages/rpm/sdrminusminus.repo sudo dnf install sdrminusminus
yay -S sdrminusminus-bin
or the server
yay -S sdrmm-bin nix --extra-experimental-features 'nix-command flakes' \ profile install github:Newspicel/sdrminusminus sdrmm-desktop
git clone https://github.com/Newspicel/sdrminusminus.git cd sdrminusminus docker compose up -d
Then open localhost:8080 and pick your radio on a Device node. The
server has no auth by default: set a token and HTTPS
before exposing it.
