Someone is going to have a lot of fun layouting that... Sometime I hate myself for starting such project.

Finally receiving low frequency data captured by my remote sensing system into my computer gnuradio ! :)

Uhhmmm I have the feeling that the siglent logic analyser option maybe useless. The pink analog trace is reading same input as the digital 6…. I fear that those long adapter cable are completely passive with no intermediate buffering and so super crosstalk contamined…

Working on a radio module using sx1255 and rp2350 with custom modulation.

Using the CMSIS DSP FFT function the RP2350 can make a 256 point floating 32bit fft in about 300us. The picture show a 10 FFT loop executed 10 time To reduce overhead.

Currently testing the X6200 from Xiegu. I’m happy overall but there is this internal tone in the 1.8MHz band…. Don’t know if it’s a known problem or my unit.

I received the xiegu x6200 today. I’ll try a field test this week end. First thing I notice they used plastic on the face with connector meaning the foldable support are fixed on plastic… not a great idea

It starts to work ! I’m happy :) VLF/ELF

Tried to mount my first hyper ram bga with hot air. I need to write a program to test it :D

I just finished a knife this one was a real challenge for me. It has some problem but overall really cool result. I need to improve my technic !
