Wow that's super cool! It's not DC to daylight but I sure don't know a cheaper way to get a 320 Msps receiver at 5 GHz.

Thanks claude

Yeah, reading stuff like:

"BRINGUP, from a cold radio: what MediaTek's ROM patch does at download (XO, pin mux, the CONN AFE calibration pulse per band, the A-die TOP init by chip ID, pads and CONN switch, the A-dies' eFuse trims); the UMAC pool layout; the common and per-band PHY initialisation; on each A-die the RF init tables, the resistor calibration and the RC filter calibration; the FEM outputs and the crystal trim."

That's not even some other language poorly translated to English, that's just a bunch of words.

Between stuff like this and math "proofs" that aren't readable either I'm really challenged to see the benefit here.

What I get out of this is that one could, if you had the documentation, write a more generalized SDR application for this hardware than the Wifi7 application. That an LLM model can provoke this behavior seems as a good existence proof perhaps?

Claude or not: It's a huge breakthrough for ham radio and signal analysis.

We now can programm more manual tuned stuff to turn this into a full 13cm and 5cm radio as it was proven to work.

Before the esp-sdr hack and this one both bands were quite difficult and pricey to reach.

Why is this a breakthrough? Just because the platform costs under $100?
BlackRabbit1•10m ago
320MSPS at this frequencies for less than $100 that can be extracted over 10GBit/s.

This was upper 4- to 5-digit of dollars worth of equipment before.

I work in this industry.

Same for the ESP-SDR project. Most likely it can be used for transmitting on S-Band for satellite control in the future (with amplifiers, dishes and maybe some filtering). The HF-Frontend is Wi-Fi certified and therefore quite clean.

An accurate description is "turn an SDR into an SDR".

With the right upconverter, that's amazing. It wouldn't take much, really, a phase locked vco from 5 to 10 ghz, mixer, and a 4ghz low pass filter to turn it into the basis of a 4 Ghz communications service monitor.
