RTL RTLSDR
[RTLSDR]

$19.95

24-1766MHZ SDR Dongle

This item is currently in stock.


The R820T2 RTL-SDR is currently the cheapest, most common and is the best in terms of general usability. The R820T2 has a frequency range of 24 - 1766 MHz (frequencies above 1.2 GHz may require cooling/heatsinking) and is fully 100%
compatible with any software for the older R820T.

At RTL-SDR.com we sell significantly improved RTL-SDR dongles at low prices. See our announcement post on our V3 units for a full overview of all the features, or scroll down for our store. Also see our V3 users guide for information on
using special features of our dongle. Our dongles come with the following improvements:

<1 PPM temperature compensated oscillator (TCXO) - Accurate tuning and almost zero temperature drift (2 PPM max. initial offset, 0.5-1 PPM temperature drift)
SMA female antenna port - Most dongles use the less common MCX or PAL antenna ports. SMA is more common, so more adapters and antennas are available for it. It is also more durable and has lower RF insertion losses.
R820T2 tuner - More sensitive than the older R820T tuner. 100% compatible with software for the older R820T.
4.5V USB powered bias tee - Can be enabled by running a simple program (see V3 users guide). This allows the RTL-SDR to power low noise amplifiers (like the LNA4ALL and HABAMP) and active antennas through the coax cable.
Experimental: HF Direct Sampling Mode - Listen to 500 kHz - 24 MHz with direct sampling. Simply connect an HF antenna to the SMA port, and choose the Q-branch to use. There is a built in 25 MHz low pass filter, but additional HF filters may
be required for optimal performance (e.g. to knock out strong MW AM).
Aluminium case and passive cooling - These units come stock with an aluminium case and passive cooling via a silicon thermal pad.
Various additional improvements compared to other RTL-SDRs - Higher quality passive components, a choke on the USB line to reduce USB noise, a much improved PCB design for significantly less internal spurs and noise, various break-out pads,
improved ESD protection, additional bypass capacitors and ferrite power line chokes, improved front end matching circuit and a better LDO.

Several improvements over generic brands including use of the R820T2 tuner, improved component tolerances, a 1 PPM temperature compensated oscillator (TCXO), SMA F connector, aluminium case with passive cooling, bias tee circuit and break
out pads for easy direct sampling modification.
