RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with 2x Telescopic Antennas
We don't know when or if this item will be back in stock.
- Enter your model number to make sure this fits.
- Includes 1x RTL-SDR Blog brand R820T2 RTL2832U 1PPM TCXO HF Bias Tee SMA Dongle (V3), 1x 6cm to 20cm telescopic antenna, 1x 20cm to 1.5m telescopic antenna and 1x 4.5cm diameter magnetic mount base with full braid RG174.
- Great for many applications including general radio scanning, air traffic control, public safety radio, ADSB, AIS, ACARS, trunked radio, P25 digital voice, POCSAG, weather balloons, APRS, NOAA APT weather satellites, radio astronomy, meteor scatter monitoring, DAB, or for use as a low cost panadapter with a traditional ham radio.
- 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 shielded case with thermal pad for passive cooling, activatable bias tee circuit, thick braid RG174 coax on the antenna base and a copper foil sticker on the antenna base for improved antenna performance.
- Can tune from 500 kHz to 1.7 GHz and has up to 3.2 MHz of instantaneous bandwidth. (HF reception below 24 MHz runs in direct sampling mode)
- The included telescopic antennas are great for beginners! Our long and short antennas cover almost the entire frequency band that is receivable by the RTL-SDR. Our antenna base has a larger more stable 4.5cm diameter and also comes with full braid RG174 coax which is a large improvement over the lower quality cabling used by the generic brands.

This is an RTL-SDR software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz of instantaneous bandwidth. (HF works in direct sampling mode - V.3 models and above only). Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, Linrad, GQRX or SDR Touch on Android. Works on Windows, MacOS, Linux, Android and even embedded Linux computers like the Raspberry Pi.
Great for many applications including general radio scanning, monitoring air traffic control, public safety, ADS-B aircraft radar, marine AIS, ACARS, trunked radio, P25/MotoTRBO digital voice, POCSAG, weather balloons, APRS, NOAA APT and Meteor M2 weather satellites, radio astronomy, DAB, or for use as a low cost panadapter with a standard ham radio.
Includes two telescopic antennas with magnetic mount. The short antenna is perfect for ADS-B when collapsed and works up to around 230 MHz when extended. The larger antenna is perfect for frequencies between 230 MHz down to 50 MHz. You can improve reception and stability of the large antenna by placing the magnetic base on any metal plate such as a cookie tin lid. For custom antennas note that this dongle has an SMA F connector (not RP-SMA).
This model has several improvements over other models. It uses the improved R820T2 tuner, has a 1PPM TCXO (2 PPM initial offset, 1 PPM temperature drift), has improved component tolerances and an SMA F connector. It also comes with a software activatable bias-tee circuit for powering external devices such as LNA's and active antennas.
Requires USB 2.0 (works on most USB 3.0 ports, but we cannot guarantee it to work on all so please ensure your PC has a USB 2.0 port just in case). Installation on Windows is simple, please Google for the free RTL-SDR Quickstart Guide for installation instructions.

As for the freq correction (ppm) both my units are ZERO and centered on the freq.Read more ›
I bought an earlier R820T based RTL-SDR a few years ago. It was a fun thing to play with, but that was about all it was - a plaything. Something caused me to recently rediscover it, and to my delight, the 'state of the art' has moved forward in the several years that have passed.
I know there are 'entry level' units currently offered on Amazon for half the price of this unit, but I decided to be 'extravagant' and get this unit instead. The manufacturer is a reputable and respected company that contributes generously to the radio community overall with an excellent blog full of great content and I was pleased to support them, and to see what I'd get in return.
The unit didn't disappoint. Quite the opposite - it exceeded expectations greatly.
It is hard to know how much of the improvement is related to the two antennas provided and in truth I attach little value to their proud claim of using 1% tolerance components - well designed circuits rarely need such exactness.
Actually, I sort of do know the impact of the antennas. Using the older product and then comparing it to the newer product with the short antenna set to a similar length to the older product's supplied antenna, I saw a few dB of signal improvement. That's nice, particularly from my unfortunately located in the basement shack. Oh - and when I used the larger telescoping antenna, I could adjust that to bring in another 20 dB of signal over the noise floor. Wow. That's stunning (but also mainly the antenna rather than the dongle).Read more ›
The 'old' plastic covered design has had major noise problems here in WA.
I stayed up most of the night enjoying my 'new' dongle and, I have been amazed at just how much difference the new design and the aluminum case make. Laptop noise is all but gone and the frequency stability is amazing. 'Should have ordered one months ago; it would have saved me a lot of time building filters that mostly didn't work.
This is the way to go! Metal case. Great stability. You will need a SMA set of adapters to daisy chain your filters, especially a SMA to F connector for a good FM trap. Do the base ground mod recommended by …....... The 'long' antenna can be adjusted to the best length for your frequency. There are “wind your own” band pass filter designs for those that need them; just google what you need.
You can buy cheaper dongles; BUT don't. You will wind up buying this one later anyway!
The SDR radio with supplied antenna, beyond the standard UHF/VHF bands, providing a casual radio listener with numerous additional options from listing to stereo FM (see photo) to NOAA Weather Service (see photo) to simultaneous monitoring of all 40 channels in the CB band (see photo). The 24 MHz to 1.7 GHz frequency range of the device not permitting for the listening of general AM broadcast.
The RTL-SDR device and very understandable given a cost of $24.95, not providing any means to decode various digital modes such as C4FM, P25, D-Star ... Since the price of the device and included hardware in the kit permits for a broad range of users, the principle limiter being access to a computer, will not delete any points for not including the necessary driver program and user interface software to control and operate the SDR.
Such device and similar, being optimal for use in advance middle and high school RF projects or part of a greater curriculum with an SDR kit provide to a small group of students (e.g. 4 students per radio). The radio providing an opportunity to learn via interaction of a real, not simulated nature, the general properties of radio to the more mathematical IF and FFT, along with carrier and transmission modes (AM, FM, USB, LSB ...), to include in a direct feedback manner for the student, how alterations in tuning, bandwidth, modes, filter, ... contribute in the received or audible output of the radio.Read more ›
