The RTL-SDR dongle has long been the standard for an entry-level software defined radio. And while we do love it, the USB dongle form-factor is simply not suited for rigorous outdoor use. This is why we've developed the SDR-STK.


The SDR-STK (Software Defined Radio Special Tool Kit, pronounced "SDR Stick") is a ruggedized two-port USB hub specifically designed to fit two standard RTL-SDR dongles, and provide a durable, water-resistant housing. Having two dongles also grants capabilities not available with just one; these go beyond simply increasing the bandwidth. With one receiver acting as a tuner, you can have the second one preforming other tasks such as wide-band scanning, listening to a trunked radio control channel, or simply receiving other information such as ADS-B packets.


The SDR-STK isn't just a one-off hardware product. In the coming weeks while the pre-order is active, we will be releasing various software utilities for the SDR-STK on our GitHub, as well as the PCB schematic files. We're firm believers in Open-Source hardware software, and we hope to use this launch to kickstart several other communication related products and projects such as better Android SDR applications, and other SIGINT tools.


The SDR-STK includes itself, and a custom 1.5 foot USB Type A Male cable. Antennas and RTL-SDR's are not included unless specified or ordered in conjunction with the SDR-STK.




This pre-order will be open until midnight (MST), December 14th, with an estimated 5-7 week lead time once the pre-order has closed. Due to this being the first round of pre-orders, the item you receive might have small cosmetic differences to the one pictured (slightly different text placement, etc.)

Any RTL-SDR compatible software can be used with the SDR-STK, but here's a few of our favorites:

We also are constantly working on SDR-STK specific tools on our GitHub. You can also find a variety of our other projects here:
