I'd suggest reinstalling update to see if problem persists, Can't hurt one of em'.

What PC software are you using. Is it NanoVNA Sharp? Are you using a NanoVNA-H (2.8") or NanoVNA-H4 (4"). If using a NanoVNA-H4 sweep points should be set to 101 for some PC programs. Roger

I have more than 50 years experience with audio, auto, computer and aerospace electronic systems and slowly moving into the 21st Century with this fancy electronic stuff like nanovna.. One thing I

Hi all, I'm running version 1.0.39 on a Nanovna H model. When connected to the PC, Every time I run an SWR scan "Get Data" I get the following errors: Corrupted data received [data 0]. Would you like

Great Idea!!! tl will help me a lot as I keep dropping those!

That was NOT the case here. I had used the very same cable some time ago to reprogran the firmware to the NanoVNA several times. Now it doesn't work. Cables go bad. At least I solved the problem. Zack

Salute! I am new NanoVNA-H user. Sorry,my English is very poor. I am industrial electrician in the dairy industry. 1.Installation:

Well, on a weird suspicion, I tried a different USB to mini-USB cable between the computer and the NanoVNA. Suddenly, everything works. So the trouble was a bad cable. That was the only thing I hadn't

I use 7/16 surgical tubing on my calibration SMA connectors. Makes them easier to hold and find when i drop them. 73 Roger KC7OM

With my NanoVNA plugged in and using Zadig, zadig lists it as a ChibiOs/RT Virtual COM Port. I then click on replace driver and once this has run its course it shows up within USB Devices as the said

Or any kind of device seen when you plug the NanoVNA In, listed within USB Controllers or USB Devices. As a suggestion, try Zadig to update the driver, this should make it seen within device manager

Ken, You are correct in all your observations. Some may wonder why the window spacing and length is not constant. With constant spacing and lengths, resonances may be set up on the line due to

I'd venture a guess that your need to retune the matching network after a heavy rain is not due to water accumulation on the window line as it doesn't wet too well, but rather extremely wet soil

I saw a similar effect when the window line is wet. I was feeding a dipole with window line. Before I removed it I tired to test the effect of moisture on the line. I built two 450-to-50 ohm

Hi Zack. Is there any kind of STM device listed in either Universal serial bus controllers OR Universal serial bus devices within device manager when you have your NanoVNA connected. Kind regards,

Sure, as long as the windows are << wavelength, then the percentage of "hole" vs "solid has an effect. if the "percentage of open space" is P%, then the effective epsilon is (1-P/100) +

All: It is encouraging to see the good results of interpolated calibrations. I think that for many (most?) portable operations, being able to set the VSWR minimum to a desired operating frequency is

Great points, Dave. The effect of the dielectric material separating the parallel lines has to be considered. Having said that, doesn’t the size of the “windows” in the dielectric make a
