Key benefits Wide, flexible receive range: Tunable from 500 kHz to 1.7 GHz to cover HF, VHF and UHF signals in one compact receiver. Stable frequency reference: 1 PPM TCXO provides accurate, low-drift tuning for reliable signal decoding and recording. High instantaneous bandwidth: Up to 3.2 MHz instantaneous bandwidth (2.4 MHz stable) for wideband monitoring and fast spectrum scanning. Robust, passive cooling: Aluminum housing with passive cooling improves durability and thermal stability without fans. Easy connectivity: Standard SMA F connector and RTL2832U/R820T2 chipset for broad SDR software and platform support. What it is and how it solves problems This is an SDR (software-defined radio) receiver based on the RTL2832U and R820T2 chipset with a precise 1 PPM TCXO. It replaces multiple dedicated receivers by covering HF through UHF in a single unit, letting you decode different services and signals with a computer or Android device. Passive aluminum housing and SMA F connector make the unit suitable for desktop use or simple outdoor installation without extra cooling or adapters. HF reception is supported via direct sampling mode, enabling reception of lower-frequency signals that many other USB dongles cannot handle. Compatibility and software Works with Windows, OSX, Linux and Android. Compatible with common SDR applications: SDR#, HDSDR, SDR Radio, GQRX and SDR Touch (Android). Uses standard drivers and integrates with existing SDR workflows for demodulation, decoding and spectrum analysis. Included antenna kit and mounting options Supplied with a versatile dipole antenna kit suitable for beginners and experienced users: Short antenna elements work well for ADS-B aircraft tracking. Longer antenna elements improve reception at lower frequencies. V-dipole configuration is appropriate for 137 MHz weather satellite reception and ISS SSTV/telemetry passes. Vertical configuration favors omnidirectional reception for common local signals. Includes brackets and RG174 coax cables for easy outdoor mounting and antenna placement. Performance highlights Chipset: RTL2832U with R820T2 tuner. Frequency range: 500 kHz to 1.7 GHz. Instantaneous bandwidth: 3.2 MHz (2.4 MHz stable). Frequency stability: 1 PPM TCXO. Connector: SMA F. Housing: Passive cooling aluminum case. HF: Supported via direct sampling mode. Practical use scenarios 1) ADS-B aircraft tracking: Connect to a Windows or Android device with SDR software and the included short antenna to receive 1090 MHz ADS-B transmissions and track nearby aircraft in real time. 2) Weather satellite reception: Configure the antenna in a V-dipole and use GQRX or SDR# on a laptop to receive 137 MHz NOAA/Meteor M2 imagery or ISS packet/telemetry during passes. 3) Public safety, digital voice and hobby scanning: Monitor local VHF/UHF channels, P25/MotoTRBO, APRS, ACARS, or use as a panadapter with amateur radio transceivers for visualizing band activity. Who this is for Radio hobbyists and beginners who want a single, affordable receiver to explore HF through UHF. Amateur radio operators seeking a low-cost panadapter or spectrum monitor. Educators and experimenters needing a compact SDR for signal decoding, satellite work, or radio science. What’s in the box RTL2832U / R820T2 SDR receiver with 1 PPM TCXO, SMA F connector and aluminum passive-cooling housing Dipole antenna kit with short and long elements RG174 coax cables and mounting brackets for outdoor aerial installation If you need a single, stable SDR receiver to cover HF (via direct sampling) through UHF for scanning, satellite work, ADS-B and more, this RTL2832U/R820T2 unit with TCXO and a full dipole antenna kit delivers broad compatibility and practical mounting options.
