I gave up trying to read the page for these reasons.

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 passed :-)

Firefox mobile on Android 111.1.0

I abandon all sites that override scroll because they're too frustrating to read.

As a data point (another aFF on Android) I could scroll down, but the experience is painful. I am interested in SDRs and have a bunch of HackFRs and dongles, but the page was very off-putting. I suspect most tinkerers that would be interested in this hardware would love an option to see all this on a static web page.

It is really cool. I have some questions.

> There are two embedded antennas to ensure that we can always correct any internal frequency drift by syncing to the cell network.

What do you mean? Do you have your own DSP stack to deal with that while user receiving/transmitting? If there is, do you provide any control over it?

Aside from that,

- What is the compatibility with open source LTE, 5G solutions(SRS, OAI, etc.)?

- I couldn't see PPS input. Are you planning to add it with daughterboards?

As usual, "taking over the scrolling" causes issues - in this case, the page is difficult to access using Firefox for Android. I usually can't get to the information at the bottom of the page (it worked once, don't know how)

Ah, I didn't realize there was more content if I keep scrolling in an unnatural way. Thank you.

PPS input/output is off to the side, look for the "User Interface Connector" paragraph on the website.

You can quickly pause whatever is running on the LA9310, push the NXP NLM stack, correct local frequency errors by synching to a cell network tower and then resume normal operation. It's going to cause a glitch, but if you want to maintain frequency accuracy it's a small cost you need to pay. Once you have absolute deviation and drift it should track quite well.

My understanding is that SRS and the like all require beefy desktop-class processors to run in?

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 and have the first batch planned for September, but further batches are probably going to be delayed into 2024 (we can't start asking for preorders before the product is tested, which is going to take time, so we can't preorder those chips…

Thanks. I have followed you on Twitter, and will discuss this with my RF fellas and get back to you on Discord or email. However, for now, I could mention 2 things that can be attractive to me as a radio amateur and RF hobbyist: 1. Any daughter board that can provide HF coverage, ideally with a few filters for the ham bands. 2. A proper shielding enclosure (shield from external noise, plus provide some heat dissipati…

:-) 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 (work in progress): https://i.imgur.com/AEYgLxU.png

And of course we agree on the software side! Soapy + GNURadio are a must. Hopefully my driver-writing skills are up to the challenge!

Just trying to get my head around SDR. What are some examples of practical use cases for a platform like this? What are the benefits of this SDR platform compared to other solutions?

compared to other radio solutions, being able to do more digital analysis on the raw signal lets you do cool things that were previously impossible

at one place, we replaced entire banks of traditional radio scanners using a single SDR

a scanner could only dial into one frequency at a time, but an SDR let us capture entire swathes of the frequency spectrum and extract concurrent streams from multiple sources simultaneously

I'd love to sit down with my Lime and end-to-end my own cell base station... one day

Yes. You can ignore this question. I should have asked you the driver first. I think you replied that question already on another comment. Thx for your explanation. Looking forward to seeing it in the market soon.

It seems to work a bit better now but it looks like it isn't working as the page stops when it goes into a transition.

There's a writers maxim, "murder your darlings". what they mean is that a work often has some styling, phrases, exposition, even whole characters or subplots that the writer has worked hard on and become attached to, but that detract from the work as a whole. So they have to be removed. I think this may be a darling unfortunately.

If you can provide a board to Alan, the lead dev of SatDump ( https://github.com/SatDump/SatDump ) to ensure compatability I'll 100% buy this board.

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 will be more requests than boards, but everyone that contributes should definitely get one from the first mass-production batch :-)

Fantastic news. SatDump and SDR++ compatibility would be sweet
