As previously mentioned, low SWR is no indication of a good and efficient radiator - an antenna. After all, a good dummy load exhibits stellar SWR over quite a wide range, but doesn't radiate too well

Thank you so much for your effort. It has been a godsend for those of us who don't have the time to track everything.

"Good" for me, might taste awful to you. Not leaving the EFHW here. It works! [email protected]> wrote:

Can someone please help me. Which of the following is correct I would figure the one that has a 50 ohm impedance but the pattern looks wrong. What am I doing wrong. Earle D Wilkinson (6Y5EW) Home

Thanks DiSlord for the new version, and Yes, time is 2000/01/01 00:00:30 (LSE) and I can not change it. Antonio-EA7HJ

Will do. I just did a 80--10 meter sweep of my 80-10 EFHW with 12801 data points on the PC app. Wow! The Smith Chart and SWR show why the EFHW is so popular. SWR <= 2:1 over the whole range!

Hi Chris the screen shots show the correct driver and the correct hex in the uart, plus the QT version using the same set up always connects as does the app from 1 of 11. This tends to make me think

I had something similar happen... Once windows decides the type of device (right or wrong), it assigns a driver. Often, when you try to load the correct driver, windows will insist it already has the

Further the COM3 port allocated when nano is connected details show as ports\VID\04B4&PID_008 joe

Using device manager and connecting the vna unit aUSB to Uart adapter shows up usb\vid_04B4&PID_0008&REV_001 usb\vid_04B4&pid_008 is this what you mean?

Upon checking the link to ST driver is version I already loaded. I double checked the addition of USB port when nanovna connected. this is before connection and this is after connecting nanovna

You say wrong port, but same port number works with QT version and app from one-of-eleven? same driver. I just grabbed st driver from web and installing now cheers joe

Anyway you use wrong Port (this for USB to TTL dongle) Find from

My nano vna states SAA-2N,? HW version V2_2?? manufactured by Zeenko if you need other information please state where to find it joe

Just for understand - you mean NanoVNA-H or H4 ?? Not V2 model? My last post for NanoVNA-H or H4

I see CDC to USART adapter - this not NanoVNA port NanoVNA port must have name Driver: https://www.st.com/en/development-tools/stsw-stm32102.html
