Genuine RTL-SDR.com product from the sole authorised UK re-seller.

V4 - HF up-converter, software bias tee, lower noise, long SMA, clock pads, 1ppm reference oscillator and improved design.

For more information visit http://www.rtl-sdr.com/rtl-sdr-blog-v4-dongle-initial-release/

Limited edition Version 4 with these features:

Built-in HF up-converter

Simply connect your HF antenna and tune in. Superior HF reception compared to direct sampling.

Software enabled 4.5V USB powered bias tee with LED

To power LNAs or active aerials via the antenna socket. Switched on and off in software.

Break-out pads for master clock

For experimental use - synchronising multiple receivers for diversity for example.

SMA antenna connector

More durable and easier to obtain and fit than the MCX connectors on standard dongles. Now much longer and with nut for panel/box mounting.

Super stable 1ppm TCXO

Much improved frequency accuracy (set-up within 2ppm) and reduced drift over time/with temperature (1ppm) over standard RTL-SDRs. 1ppm = 1 part-per-million = 145Hz at 145MHz.

Metal Case

Extruded aluminium enclosure gives better screening, reducing interference.

R828D tuner chip

Tri-plexed RF front-end with extra filtering.

NOTE: This is the newer V4 design, and it requires updating to the latest drivers to work. Before purchasing, please ensure that you understand that not all applications work with the V4 yet! Compatibility with most programs on Windows, Linux and Android is now OK, but MacOS is still catching up. Please consult the V4 users guide for more information: http://www.rtl-sdr.com/V4/

Included is one item only:

  • RTL2832U/R828D 1ppm TCXO USB stick V4
There is a huge range of uses for these sticks and masses of documentation and software on the web. Because of this and since new software is released all the time, we do not include any SDR software. No OEM driver CD is included with the device as they are not used in this application. For SDR use, consult your SDR software documentation or website on how to install third party drivers.

The frequency range of an RTL-SDR is nominally 24 – 1766 MHz. With the built-in up-converter HF signals below 30MHz can be received.

Please note: The SMA is not a reverse polarised type as often found on wi-fi equipment.


Use of this stick as an SDR receiver is experimental. Please research the subject thoroughly before buying and make sure you have the information, software and skills required to use the device. We cannot provide support for any application or software, however each stick is individually tested in our workshop with our Marconi test set to make sure it reaches you in working condition.
