In January there was an item on viewing spurs from HTs ect. I ordered two 40 db anttenduators, 1, 10 & 1, 50 watt. They showed up while I was in the hospital with a heart attack. Now I have a battery

Rudi. THANK YOU for that awesome reply! Much appreciated!!! ron N4UE

Hello Jean, I have documented a practial example for measuring the cable impedance, see: https://www.rudiswiki.de/wiki9/nanoVNA#Coax_Cable_Impedance Is that more understanable for you? 73, Rudi DL5FA

Your response does not address the problem I encountered.

Yes, pictures are worth thousands of words! Once calibrated, what does the SWR show with nothing connected to either port - preferably, display the Smith Chart. But if you are not familiar with that,

Carl, It would help if you provided a picture of your screen and test set-up. Sometimes new users aren't used to operating an analyzer with two channels and try to perform SWR measurements on CH1

19 Hi Herb, Peace be upon You and Yours All. I had to reinstall the software and take my Nanovna - H apart and using a jumper to revoke it. I tryed bevore without installing the software new, no

Make sure you are set up for Port 0 reflection. Bob

Larry, I have the manuals and read through everything I can find on the interweb. Also Youtube videos. Every time I try to do the SWR readings it shows SWR 1.00 and a straight line. On the hand held

Jean, here is how I do it. 1. Set up for Smith chart2. Run a sweep to see how the curve runs around near the edge of the chart3. Narrow the sweep range to a bit more or less than the frequency where

Hello all. Still puzzled by all the stuff we can do with this device that were out of reach beside buying big bucks HP or (bigger bucks) R&S . I'm running a genuine NanoVna H with the last eddy

Thank you Luc. That is a marvelous presentation. Thank you very much for all that work. Larry, AE5CZ

Programs to fix windows 10 driver issues are usually a scam. -- NanoVNA Wiki: /g/nanovna-users/wiki/home NanoVNA Files: /g/nanovna-users/files Erik, PD0EK

This topic was already discussed here a few times and it's written-up in the Forum Wiki. Win 10 isn't supposed to need a separate driver for the nano. Why not just provide the website here?

After using Nanovna-saver for awhile, it fails to find the virtual com port. I have the solution ? well, not me, but I found someone who does. They have a program that fixes the driver on Win10.

Read the User Guides, Carl. There are several on the forum. To perform a complete reset, with no calibration, you need to connect the device to a PC and use TeraTerm or another comm program to talk to

More info, I only want to use this unit as an antenna analyzer at this time, Carl

I got my Nanovna-H a week ago and after many tries I can't get it to display SWR trace. I now have it so messed up I need to restore it to factory default. So I seem to be dumb and need help. Can

Sounds like a static discharge may have done something. The schematic is available so why not do some simple troubleshooting? Make sure the 3.3v regulator is working: 5V in and 3.3V out. Disconnect

I have had my nanoVNA since September. Have loaded several different versions of FW without issue. Today, after doing a calibrate, it locked up. Unresponsive to touchscreen. NanoVNA-saver can't talk
