Great Mike. Can you share that video source? Doug, VA3DKA -- This email has been checked for viruses by Avast antivirus software. www.avast.com

Of all the stupid things. NONE of the videos showed calibration on the end of the feed. They all did it right at the side of the vna! I finally happened on a video that did it at the end of the coax n

I thought that when you do cal, you disconnect the antenna and do cal at the end of the feed line. Which way is correct? Chris Sent from Mail for Windows Sent: Monday, June 12, 2023 2:14 PM To:

Hi Mike. I have been following your questions and can sympathize with your dilemma re calibrating and configuring your NanoVNA. I struggled with this aspect too, until I found this YouTube video,

Ok sorry to be such a pain. I really want to get this up and rolling for field day and some demonstrations coming up and I feel like a idiot for not catching on. Thanks for being so patient with me.

Mike, Just set the start and stop frequencies to the widest approximate frequency range where you expect the antenna will be tuned to. For 10M try 25 to 32 MHz. The calibrate for this range. Set the

Ok Roger, ? I watched the video but didn't glean a lot of learning from it. I'm not understanding were he is reading his freq from ? ? At the moment I'm trying to set the coil in the center

Don, You can learn how to update your firmware in the Absolute Beginners Guide located in the Files section of this group.

Dear Roger, thank you very much for reply. In the meanwhile problem solved, it was the usb cable which was interrupted inspite of looking like brand new. That is why I thought that might be a W11

Hi I have a NanoVNA with version 0.8.0 firmware Dated June 2020. Is there a later version for this early NanoVna? If so are ther some instructions somewhere. I did this in 2020 and it seemed

Mike G8GYW. This VA5 sounds pretty good from the write up in their web page. Is it good enough to be the only 1 in your kit for a while? Ed

I don't know the OP's reasons for wanting to know but I'd think it useful for knowing how much is used on a run, how much is left on a reel and for tracking down faults to think of just a few.

I'm trying to fathom the reason for knowing the exact physical length of a piece of coax, or it's exact electrical length. What are you trying to do here, phase yagis on 14 mhz.... or building a 4

Thanks Roger and everyone else that is helping me learn on this journey. Eventually I'll get it all locked down and be able to pay it forward I hope ?

1) use the NanoVNA to sweep and find out where 1/4 wavelength is (i.e. peak in S11 magnitude). Knowing the frequency where it's 1/4 wavelength, you can compare to free space wavelength. 2) Use the

Mike, W2AEW has an excellent series of videos on how to use the NanoVNA to measure and adjust antennas. I think you will find this one worth watching. https://www.youtube.com/watch?v=xa6dqx9udcg Roger

If you can't see the NanoVNA-H as a COM port in Windows 11 after plugging it in that means that the driver is not installed. Windows 11 should install it automatically but sometimes it fails to load.

Very good point about actual VF vs published VF. There are several ways to quickly get the actual VF of the cable using a NanoVNA but the OP ("Anne") doesn't like posts that go beyond specifically
