SDR6-V3: RTL2832U+R860 SDR receiver, 500kHz–1.7GHz, 1PPM TCXO, Bias-Tee support.
On July 24, 2026, HTOOL launched the SDR6-V3 high-performance SDR receiver. Built on RTL2832U+R860 architecture with 1PPM TCXO and software-controlled Bias-Tee, targeting radio enthusiasts, amateur communications, RF R&D, university teaching, and spectrum monitoring.
Dual-chip: 500kHz–1.7GHz continuous coverage, max 3.2MHz real-time bandwidth, 2.4–2.56MHz stable; native Q-branch direct sampling for HF.
1PPM TCXO: ultra-low drift for DMR, P25, ADS-B, AIS, NOAA weather satellite decoding.
Bias-Tee: software-controlled, 4.5V/180mA max, overcurrent protection.
Design: 88×25×13mm aluminum enclosure, USB 2.0, cross-platform.
