Great to partner with @SETIInstitute and @gnuradio on a recent hackathon at the Allen Telescope Array sponsored by @ARDC_73 https://t.co/qxvmeccVRy

The Australian GNU Radio Days event is running September 23-26 in Adelaide, hosted by Flinders University. Three days of talks and workshops followed by breakouts. Still a little time to submit a talk or booth if you're interested! https://t.co/rApkqHAGet

New LiteX M2SDR dashboard: Runs alongside any SDR app, spies on FPGA/Cores internals, and makes config/debug less of a nightmare! 😂

Testing the NVIDIA Jetson Orin Nano + LiteX M2 SDR as a Compact/Powerful Standalone SDR Platform:

✅ Validated with GQRX at 61.44 MSPS (stable, no dropouts)
✅ IOMMU configuration guide updated in LiteX M2 SDR README (https://t.co/sI6O9pGc9t)

I'm thrilled to share I've successfully defended my PhD! Fun, pain, and so much learned with great people. I've also gone traveling with my wife and we're going into 2025 with fresh minds and eagerness to make the most it.

Anyone with a challenging problem need another brain?

I'm at #38C3! Hoping to meet up with people, so message me here, #6408 on Eventphone, or catch me around the SDR CTF.

[Derek Kozel @derekkozel]

Friday's going to be an exciting day for me, to find out why maybe follow me on 🦋?

@SV1CAL Great, enjoy! If you do figure out a nice/efficient way of adding impairment corrections to it I'd love to combine them and add it to the main block library.

[Derek Kozel @derekkozel]

@will_whang Now that's very interesting! Certainly makes things much simpler from a circuit perspective. I use bifurcation on my desktop, I'll have to try out a TB3 device with device connect time bifurcation.

[Derek Kozel @derekkozel]

@will_whang I can Google, promise.

ASM2812 has Gen3 x4 uplink and x1 * 6 downlink

[Derek Kozel @derekkozel]

@will_whang Ah, pity it's only Gen 3 x2 lanes for the uplink. Any chance you know of a similar chip that's x4 uplink?

x2 is still enough for most of my imagined usage, but pity to leave capacity on the floor as the Thunderbolt 3 link I have is x4 capacity.

@philcrump2 @IanJohnBuckley @davegkq I took one (long) look at the size/weight of the whole setup and the cadmium paint warnings and passed on buying any, mostly without regret. I do want to get dish on a rotator, but I think a larger backyard is a prerequisite. Till then, the best dish is someone else's dish!

[Derek Kozel @derekkozel]

@IanJohnBuckley @philcrump2 @davegkq Yep. ex-naval. There was a whole line of them available in 2018.

[Derek Kozel @derekkozel]

@IanJohnBuckley @philcrump2 @davegkq No... the radome designer definitely knew what they' were doing. The interior had cancer warnings (on the one I looked at) and sanding was a major no-go.

[Derek Kozel @derekkozel]

I'm free to go to Chaos Communications Congress for the first time ever thanks to a few stars aligning, but I'm not directly connected to a community group which has received vouchers. I'll email some friends, but I thought I'd ask if anyone here can help?

The top five teams are within 100 points of each other in the #GRCon24 #CTF! It's not too late to join in and decode some mystery signals. https://t.co/S2B5zFIjyi
