SparkSDR: The All-in-One SDR App for Serious Radio Enthusiasts

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.
