Are there recordings?

Strange, my LCD screens of nano and tiny do not show any artefacts, only the captured data on PC. But it's only a minimal issue in any case.

Robin, Good hint, should work for the bigger ones now - untested because of the HW not (yet) available. Martin usage: nanovna_remote.py [-h] [-d DEVICE] [-n | --h4 | -t | --ultra] [-z {2,3,4}]

I think this related to LCD driver, on screen capture i read LCD memory and send to CPU (you can see it also on Nano or Tiny LCD at right bottom) Artefact present on all LCD displays based on ILI9341

Martin, 1) thanks for doing this, it's much appreciated. 2) the link below took one straight to the code, where lines 60-64 show: which is OK for an original nanoVNA(-H) or a tinySA. *However*, the

The screen capture shows artefacts at the bottom of the image in the far right column. This is independent of the respective device and the recording program used; tinySA also shows the same

Hi Barry. This sounds like a really invaluable project. It is just too bad that we didn't know about it sooner, so that we could take in all five sessions. Is there any possibility that any previous

This is what I see with the NANO VNA standard LOAD (50 ohm dummy load R) Nothing unusual here. de k3eui Barry

Nano VNA graphs using VNA SAVER Lots of folks have asked me how the REFLECTION Coefficient S11 graph, the RETURN LOSS graph (dB) and the SWR graph compare. Basically they all show similar aspects of

Kirk No, I did not record them because I wanted to encourage questions/comments and when you record these sessions, (some) folks are hesitant to ask questions or respond. Barry

Hi, Barry, Did you happen to record those previous sessions? Thanks, --Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com and on the Amazon Kindle (soon)

Sorry ... I meant to say: These parts are designed for turning on MOSFET gates so I suspect they stack as many photodiodes in series as they need to get the required voltage. Eamon

Here's one that will do 10V https://www.vishay.com/docs/84639/vo1263aa.pdf (it's far from the only one). These parts are designed for turning on MOSFET gates to I suspect they stack as many LEDs in

Apparently, those 1000V PIV (the 1n4008) *are* PIN diodes - something about the voltage rating - the 800V versions are not. However, there's some commentary about different manufacturers being

Miro, yes, Elecraft uses such high voltage rectifiers as PIN diodes in several of their products. They use true PIN diodes in some others, and sometimes they even mix them. What kind of diodes they

Hi, as written just around the corner /g/tinysa/topic/tinysa_remote_py_python/94944540 there's a new tool in my toolbox:

Dave - LogMag for S11 just sits there at 10db/0.05db no matter what connector i put on the unit, OPEN, SHORT or LOAD. It doesn't fluctuate at all. Smith Chart stays at -133mOhms 521nH. No fluctuation

Tom - I've ordered a couple to have on hand. Will take the one out. Thanks for the suggestion. John
