Safety & Usage Notes
This device is receive-only, it cannot transmit radio signals.
Do not use near high-power transmitters. The maximum input power is +10dBm; excessive input power will damage the device.
It is normal that the metal shell feels warm during operation, because it acts as a heat sink.
If you connect outdoor antennas permanently, please take protective measures against ESD and lightning strikes.
Please download the latest drivers and software via the official link (www.rtl-sdr.com/QSG) for normal use.
Avoid using in humid environments or areas with strong electromagnetic interference to ensure signal quality.
The SDR-V2 radio receiver devices are all based on the RTL2832U chip as RTL-SDR receivers, but they come with different tuners: one with an FC0012 tuner, supporting 22-948.6MHz; and one with an FC0013 tuner, extending the range to 22-1100MHz and supporting L-band input.
Note: The RTL-SDRV2 can't receive shortwave, because the RTL2832U chip in the RTL-SDR itself doesn't directly support shortwave reception. It lacks the direct downconversion feature for the HF band (below 24 MHz), so due to hardware limitations, the RTL-SDRV2 can't pick up shortwave. If you want to receive shortwave, it's recommended to go with the RTL-SDRV4.
HTOOL SDR V3 Software Defined Radio Receiver with Suction‑cup Antenna Kit
The SDR V3 is a cost‑effective USB‑based SDR receiver equipped with 1PPM high‑precision TCXO temperature‑compensated oscillator and built‑in Bias‑Tee power supply. It supports wide‑band reception from 500kHz‑1700MHz, with an aluminum alloy enclosure for passive cooling and stable long‑time operation. Matched with magnetic suction‑cup antenna, it can be easily mounted on metal surfaces to improve receiving performance. Compatible with Windows, macOS, Linux and Raspberry Pi. Working with open‑source software such as SDR#, HDSDR, GQRX, it supports air‑band monitoring, ADS‑B aircraft decoding, ham radio reception, spectrum analysis and weather‑satellite demodulation. Ideal kit for radio hobbyists, educational research and RF testing projects.
- Upgraded R828D Tuner & Built-in UpconverterReplace the traditional tuner with high-performance R828D chip. The built-in upconverter removes 14.4MHz Nyquist folding, enhances HF reception sensitivity, and supports adjustable HF gain for better weak signal capture.
- Multi-stage Optimized Filter SystemTriplex input separates HF/VHF/UHF bands for better isolation; additional switchable notch filters suppress strong broadcast interference, reduce image signals and improve overall anti-interference ability.
- 1PPM High-precision TCXOBuilt-in temperature-compensated crystal oscillator provides outstanding frequency stability, ensuring accurate frequency tuning, which is essential for ADS-B, satellite signal reception and weak signal monitoring.
- Integrated Programmable Bias TeeSupport power supply for active antennas and low noise amplifiers directly, no extra external bias tee adapter needed, simplifying field wiring and equipment combination.
- Metal Heat-dissipating Housing & SMA InterfaceFull metal shell serves as a heat sink to lower operating temperature and reduce phase noise. Standard SMA connector ensures good signal compatibility with most antennas and RF accessories. Max input power: +10dBm.
- Wide System & Software CompatibilityPlug-and-play via USB 2.0 interface. Fully compatible with Windows, Linux, macOS, Android systems and classic software like SDR#, GQRX, HDSDR, CubicSDR. No complicated configuration for beginners.
- Low Heat & Stable OperationOptimized power design cuts power consumption and heat generation compared with older versions, supporting long-hour continuous work without performance attenuation.
- Wide Frequency CoverageFrequency range: 500KHz - 1.766GHz, fully covering shortwave, FM broadcast, aviation, marine, GSM, Bluetooth and other common RF bands to meet diverse usage demands.
