Dow-Key Microwave 411C-220832 12V relays I got a handful from equipment that we tossed into recycling at worksites. They never seen a signal larger than -10dbm and are perfect for circuits like this.

Where did I purchase? eBay and it took about 4 weeks to arrive. Why three, now 4, vnas? I wanted one of each of the identified versions to test whether one was better. Whether shields made a

Ahh the linux holy wars. I can assure you that nanovna-saver works fine on Fedora. It's a pure python program though it needs some libraries that are available in the repository but the packages are

If you are waiting to get another nanoVNA, you can get this when it is available on ebay or aliexpress. I got mine from Taobao direct. But you need to solder in the connectors and the components.

Hello, I am sorry, but you keep giving links rather than comment is very tiresome for me. | Finally, allow us, please, to comment that, in our humble

One of the parameters specified for a VNA is the * raw uncorrected source match and * raw uncorrected load match. The better the raw performance, the better the corrected performance. I measured these

I would be interested in finding that out also. Thanks, Dick, W1KSZ Sent from Outlook<http://aka.ms/weboutlook> ________________________________ Sent: Tuesday, October 15, 2019 4:11 PM To:

Kurt, Please find attached below the Smith Chart after tuning the parameters. The S11 plot after tuning is the last chart in the first post #4963 above. I think there is a misspelling in so far you

Hi Bryan Congratulation. Tweeking parameters in NanoVNA-saver is great fun. You missed to show us a sweep of the coax cable after tuning to celebrate the victory ? I think there is a misspelling in

Warren, where did you purchase your NanoVNA-F? Dave

I would like to set up Cal Files for different parts of the Spectrum. One procedure I have talks about doing that, but one of the steps (after setting the Frequency Range) is to hit "Reset". Now

*There are several reasons I believe TRL calibration is not too practical on a low-cost VNA.* 1) The length of the line section needs to be between 20 & 160 degrees electrical length - ideally 90

But why do you have more than one NanoVNA?? Am I missing out on something?? (I understand getting a -F in addition to the original)... Mike WY6K "... somewhere in the distance, there's a tower and a

Good information.? I have one mystery though - what do you do with 3 NanoVNAs?? Why multiples? Mike WY6K "... somewhere in the distance, there's a tower and a light, broadcastin' the resistance,

That is a nice solution. Who is the manufacturer for the relay? Quality SMA packaged relays are not cheap! Thanks,

Hi Wes, NanoVNA-Saver should work fine on whatever flavour of Linux you run, assuming it has at least Python 3.7 (maybe even 3.6) and is 64 bit. PyQt5, the user interface library used, isn't available

There was a USB c issue with NanoVNA devices up to a few weeks ago When hugen added 2 additional resistors on the connector that tell a USB c host device what is being connected.? This was discussed
