For those of you who, like us, don't want to stop where the spec tells you to stop, for those who like beating the record, here is a demo of XTRX receiving 140 MSPS (140 MHz) of SISO spectrum. Read the full update.
Now that the XTRX design is finalized, we've published its 3D model files and pinouts. Read the full update.
When we launched the campaign, we had our XTRX prototypes running stable at 80 MSPS (both SISO and MIMO), but we were saying that we're confident we can go up to 120 MSPS. Read the full update.
First of all, a big thank you all for supporting XTRX campaign and congratulations to everyone interested in SDR! The $108k/120% funding raised for XTRX so far is the best evidence that it's time for off-the-shelf, embedded SDR solutions. Read the full update.
We've received so many questions about the HF band and RF performance lower than 30 MHz, that we decided to do a special update. Read the full update.
TL;DR: a very positive response to the Octopack pledge level; we've corrected a mistake in the survey we sent out yesterday. Read the full update.
We're giving away a handful of XTRX revision 3 boards to the best proposals on how to use them. We've also released a bunch of software. But first, a big thank you. Read the full update.
Thank you for signing up for updates on the XTRX software-defined radio project. The XTRX campaign is going live today; please follow along, pledge, and help spread the word about this project! Read the full update.
Check out slides from our presentation at the GNU Radio Conference 2017 and many other SDR related talks at the GNU Radio Conference 2017. Read the full update.
A few people asked us about ARM support and most of them were interested in NVidia Tegra, so we grabbed a NVidia Jetson TK1 development kit for testing. Simple cross-compilation of the driver gives us 22 MSPS right away. Read the full update.
Life of a hardware company is never easy. Every error in hardware leads to significant amounts of lost time and money. You can’t just roll-out a hotfix to fix an issue. Which is why we’re taking a rigorous approach to testing our hardware before releasing it to the public. But today’s update is not about testing. Read the full update.
Most of the updates so far were related to hardware design progress, but hardware is nothing without software, so it’s time for a software update. Sergey has been putting massive amount of work into making sure XTRX software is high performance, flexible and stable. And making sure all most popular applications are supported. Read the full update.
Planning to attend GRCon’17? Drop us a message if you want to meet, or just find us there to chat! Read the full update.
Andrey has just finished a redesign of the RF part of XTRX to reduce Tx-Rx leakage and external interference. XTRX has much stronger RF shielding now to protect the most sensitive parts of the RF chains and will hopefully pass our internal tests. Read the full update.
Answering most frequently asked questions about a carrier board design for XTRX. Read the full update.
First of all – the project is not dead. :-). We decided to spend a bit more time optimizing RF performance to make sure we don’t disappoint you. Read the full update.
We often get asked how many receive and transmit chains does XTRX have and whether you can tune them to different frequencies, so I decided to clarify this once and for all. Read the full update.
We recently gave a talk and a workshop at 33rd Chaos Communication Congress aka 33C3 on funny and not so funny issues one faces while building a high performance SDR. Read the full update.
Just got the first batch of test boards. Feels really good to hold them. Onto the testing. Read the full update.
First prototype PCBs are ready for assembly at our fab! Can’t wait to get our hands on the prototypes. Read the full update.
So while we’re waiting for the first test run of the boards to be manufactured, I have been working on advancing the software side of things. Read the full update.
A number of you requested more technical information on the board. Below are the most important parameters of XTRX. We will provide a more detailed view into each of these in followup posts. Read the full update.
