The wirebonding learning continues, this is a uW amplifier mounted from scratch.🙈🙈 #rfporn #ghz_bands #amateurradio

@ibelings You will release SpectraFlux??? ;P

SpectraFlux can now see and decode airplanes. PlutoSDR at 1090 MHz, ADS-B decoder written from scratch in Swift. 70 aircraft from a tiny antenna on my desk. It helps to be on the corridor to KATL.

@ibelings I prefer the most modern ESA Analyzers, they are the last of the good ages of HP/Agilent are strong and pure heavy iron 🤓

@sdf_pubnix In the 3 last month 4 rifa caps burned here from HP laboratory gear...

Let 2026 be the year of the RiFA!

@ibelings Looks great! when will be released??? :P

Got pySpectraVue running way faster. Now it processes the full sample buffer and batches waterfall lines in a single repaint. Huge difference. Python/PyQt6/PyTorch/NumPy. Torch handles GPU FFTs on Apple MPS and CUDA. Talks to USRP B210 and RFSPACE NetSDR.

@F5OEOEvariste @enjoy_digital Please keep us informed, tnx!

Start of an adventure : thanks to @enjoy_digital !

@amsatdl Ok, tnx!

@eb3frn 1 Hz size of bin

VOYAGER-1 live on the YouTube stream from Bochum.

@ibelings I’m anxious to see the next one ;)

These are still some of the best performing SDRs. What's next?

@mov_axbx Great machines! interested to join

Reply or DM if you want to be added to a vintage computing GC If you want to repost this, that would help us have an active GC that isn’t too quiet :)

@F5AYE @xjamesmorris Not planned , you see it interesting?

@eb3frn @xjamesmorris Hi Iban, Do you plan to publish a publication on this engraving method? 73Jean Paul F5AYE

Black magic to create new 47GHz devices 😇😇 #GHz_bands #hamradio #hamr

@g8kmh @xjamesmorris In the video was a FR4 for testing, but also using very thin Rogers for microwaves and millimeter bands

@eb3frn @xjamesmorris Iban, what PCB material are you now using?

@BoscoMac I understand you, I’ve the same “problem” with the E3631A power supply 😅

If someone asks you if you have enough 3458A, you say no! 😬 #3458a #keysight #agilent #hp

@ibelings Tengo los dos. Del NetSDR, el SN #0001 😜😜

@eb3frn tienes un NetSDR o B210? Son los unicos que funcionan y no tiene demod.

🚀 Major progress on PySpectraVue, a Python-based spectrum analyzer optimized for precision! Image shows testing with 512k FFT and various colormap files. Features pixel-perfect rendering (no smearing in time or frequency), exact frequency displays, high-res zooming, and hardware-accelerated FFT via PyTorch (MPS/CUDA). Inspired by the big guys, PySpectraVue builds on 25+ years of SpectraVue SDR legacy. #SDR #SignalProcessing #Python

@ibelings Como va el PySpectraVue ??? :)

@eb3frn esta semana le trato de agregar el B210 y NetSDR

@ibelings Bien! 😍😍

@teraytech The important part are the ridges and coax support and it are metallic (aluminium¿?) the external part not the reistance, not is critical

Well the cheap conductive paint i have doesn’t seem to have a good low resistance even I literally used the entire 150ml in the bottle to make it thick But I can’t really buy the original one, it cannot be shiped out of NA Currently Im thinking about covering copper foil inside

@teraytech Tnx! :)

Looks like we’re pretty close to the finish line🤔

Hola @edutaboada me gustaría contactar contigo por un tema profesional. ¿Como puedo ponerme en contato contigo? Gracias.
