Whether you’re deep into digital modes, exploring HF bands, or just getting started with software-defined radios (SDR), SparkSDR is a game-changer you should know about.

Developed by M0NNB, SparkSDR is a cross-platform SDR application designed to work seamlessly with Hermes Lite, Red Pitaya, Apache Labs radios, and even SDRplay.

Works Across Platforms

One of SparkSDR’s standout features is its flexibility. It runs smoothly on:

• Windows 7 and up
• Linux (x64 and ARM, including Raspberry Pi!)
• macOS

So no matter what system you’re using, SparkSDR has you covered.

Why SparkSDR Rocks

Here’s why operators around the world are switching to SparkSDR:

Smart, Built-in Digital Modes

No more messing around with virtual audio cables or COM port routing! SparkSDR comes fully loaded with built-in support for popular digi modes like:

• FT8 / FT4 / FST4 / FST4W
• JT65 / JT9
• WSPR
• PSK31

You can monitor and decode multiple modes simultaneously using virtual receivers that share the available slices of your SDR.

Exceptional Audio and DSP

SparkSDR features low-latency audio and a cutting-edge DSP chain. Plus, it supports SSB compression using a controlled envelope clipping algorithm for crisp, punchy audio on transmit.

AI-Powered Noise Reduction

Tired of fighting with background static? SparkSDR includes neural network-based noise reduction, making weak signals easier to pull from the noise floor.

Touch-Friendly UI

Running SparkSDR on a tablet or touchscreen PC? No problem. The UI is designed to be intuitive and touch-friendly, perfect for portable setups or ham shack touchscreens.

MIDI + CW Keying

Integrate your MIDI controller to run the rig like a pro studio mixer, or hook up a low-latency CW keyer and start pounding brass with confidence.

Built-in Time Sync

It even supports frequency correction using NTP, so your rig stays right on frequency — ideal for weak-signal digital modes like WSPR or FT8.

Note on Transmit Support

Currently, transmit capability is available only with Hermes Lite devices. However, receive functions work across other OpenHPSDR-compatible radios. Some advanced features (like filter switching) may vary depending on the radio.
