SDRplay RSP1B — Wideband Software Defined Radio Receiver

The SDRplay RSP1B is a wideband software-defined radio receiver covering 1 kHz to 2 GHz. Reviewed and recommended by Tech Minds in February 2024, who noted that the improved noise performance under 1 MHz results in significantly better reception of NDB signals from airports — a real-world improvement over the RSP1A. Matt demonstrated the RSP1B with SDRplay's SDRconnect software, showing features including IQ recording, asymmetric notch filtering, and the remote server capability for network-based SDR use.

The RSP1B covers a wider frequency range than the RTL-SDR V3, includes a built-in bias-T for powering active antennas, and operates at up to 10 MHz of instantaneous bandwidth. Compatible with SDRuno, SDRconnect, GNU Radio, SDR#, and HDSDR.

• Frequency range: 1 kHz – 2 GHz
• ADC: 14-bit
• Instantaneous bandwidth: up to 10 MHz
• Software: SDRconnect (Windows/macOS/Linux/Raspberry Pi)
• USB powered, no external supply required
