Thanks Martin. My Nano VNA is still original, 0-950MHZ or so, I never did any firmware upgrades. It worked well, so I left it alone ;-) 73 de Andy

The error message is now clearer: 'capture error - does the device support the "capture" cmd?' I also added better device type detection (name and screen size) - GitHub updated:

Hi Martin. As it started before Christmas.... Has anyone still got their Christmas lights on? Cheers Ian/MI5AFL

I should have clarified this point with a bit more detail. What I meant to say was that it is rare to have a situation where only the H or E field component exists. In most cases you are likely to be

Hi Martin, Yes understood. Good luck with your interference hunting. One tip. Wear a high Viz jacket if you are walking around the neighbourhood with an antenna and box of tricks. No one pays any

I think it it the other way round :) - The old firmware doesn't allow remote control, but you could try a firmware update that also provides other useful functions.

I've done nothing yet apart from a quick experiment with the Xiegu to see it that would help to search for it. I cannot easily rotate the loop without relocating it - it is pinned to a garden fence

Thank you Klaus

You can use sweep center {freq} and sweep span {width} -- Klaus, DL5KV

Hello, I would like to control the tinySA ultra for measuring the power value(peak) at 868MHz?via serial commands. How to set the start and stop frequency? Or is there a command to set center

Most likely the loop is much closer to the noise source or the noise source is almost pure vertical polarization and the loop which is probably vertical can hear it while the dipole can’t. ?I have

Maybe in the near field this could be true, but that diminishes fairly quickly. Loops tend to have better common mode rejection than dipoles, and this often the reason they appear to be less prone to

MartinMy understanding is that loop antennas respond to the magnetic component of the EM wave and dipoles respond to the electric component.? In your case, I'm not sure if the distance to the source

Hi Martin, I realised my mistake soon after posting, the leading / for the comport was missing. To be honest this test was part of a something I abandoned many months ago on my Linux Mint 20.3

Andy, The error is: "-d dev/ttyACM0", must be "-d /dev/ttyACM0" But no need to use the -d unless your device is at an unusual port, e.g. on a mac. Just use: sudo python3 nanovna_remote.py -z2 What's

Thanks Isidrio - but they are quoting the same delivery date as my local supplier... Martin G8FXC

I have installed this script, but I think that I am not specifying the comport correctly. My attempt to list ports gives this: dmesg | grep tty [??? 0.112805] printk: console [tty0] enabled [??

Hi, youcan look in the eleshop.eu They are aprooved seller, I have ordered my TinySAs and my Ultra from them. Good seller for my personal experience. All the Best, Isidro ?BlueMail for Android
