you can run SRSRan on a small self contained SDR such as the Seeve board. Throughput is not going to be good as a custom stack as it's unoptimised, though. https://rfnm.com/blog/in…

> When my AoA sensor fails, then what? crickets, let's just randomise which sensor we use during boot, that ought to do it!

Strange. I haven't changed a thing. Just to confirm, the problem yesterday was that the website would be stuck, not that you couldn't move down further by scrolling in an unnatural…

:-) The HF daughterboard is the only thing that's missing, I think. To be honest, I was hoping for someone to suggest a nice design on that front. Here is a render of the enclosure…

PPS input/output is off to the side, look for the "User Interface Connector" paragraph on the website. > What do you mean? Do you have your own DSP stack to deal with that while us…

Is this with an older Firefox version maybe? I've tried with a relatively recent one and couldn't reproduce, but I'll look at the logs and try to fix this now that the HN storm has…

It would need to be a different design entirely.

NXP are open sourcing a lot of the support stack for the LA9310 to go along with this product release, but I'm afraid they consider the VSPA DSP to be highly proprietary, yes. Exam…

The schematics will be released publicly when the product is shipping, but it won't be OSHW. I don't want to end up like the HackRF, where one small company is burdened with suppor…

You'd probably want something way more sensitive than that, right? Something that goes well into the micro/nanovolts rather than millivolts. But it should be reasonably simple to d…

8x ADCs and 2x ADCs @ 153 MSPS -> 4x RX I/Q pairs and 1x TX I/Q pair. The way the math works, you can sample a 153 MHz signal at 153 MSPS using I/Q, or you can use each ADC line to…

We need volumes, so the best I can hope for is people join the waitlist and pre-order when we show a functioning prototype. We already placed sizeable orders with the manufacturers…

Here is a fast render of what the enclosure might look like (work in progress): https://i.imgur.com/AEYgLxU.png The idea is however you get shielding and cooling, sit it on the des…

A few practical use cases that are not easily covered by similar platforms: 1) Direction finding thanks to the 8x 153 MSPS ADCs and coherent clocks. 2) Mixed domain analyzer: have …

No, I think your feedback is fair, MMCX connectors are certainly more durable. Maybe the tradeoff there is that they are not as common, so I might need to include adapters as well.…

I don't like them either, but I couldn't find a better way to provide the clock in/out feature and still fit in that area of the board. The optional OCXO on the opposite side of th…

I can't commit to pricing before I have decided on a partner for the distribution (DIY vs Kickstarter vs Crowdsupply, they all come with different costs and tradeoffs), but $550 is…

The Granita board should already work down to 10 MHz. If you need to go lower, I (or someone else) would need to design a custom RFNM daughterboard for low frequencies. You could d…

A few reasons: (1) The AFE7903 wouldn't allow for any modularity in the system (look at what we are calling the RFNM interface on the website, I think that's the real reason this p…

We should have a fair number of boards going around in a couple of months (10-20), when the first batch is done and basic software is complete. Mostly as loaners at first as there …

I routed the i.MX block like a normal human being, then rotated everything 23 degrees to (1) avoid the fiber weave effect and (2) not collide with any of the mounting holes, as tha…

*i.MX 8M Plus, please :-) The 8M Plus is not that different from the RPi4! Yes, of course, this will be sold to anybody and be very, very competitive, like in the order of ~$550 in…

You need to work directly with NXP. Our first big batch will be here in September. We could have had them earlier but there are plenty of different moving parts, things to do and s…

I designed this system (not the chip, clearly), so feel free to ask any questions!
