The RTL-SDR Blog V4 is a USB software-defined radio receiver built around the R828D tuner and RTL2832U ADC, covering roughly 500 kHz to 1.766 GHz through an SMA input. Its main upgrades over older RTL-SDR dongles are a 1PPM TCXO for stable tuning, a built-in upconverter for better HF and shortwave reception, and a software-switchable 4.5V bias tee. It comes in an aluminum case with a diode-protected RF front end. The best new price is $34.99 at tindie.com as of November 5, 2026, with three stores listing it new.
