Guys, you can test this NanoVNA MOD v2: https://www.rtl-sdr.com/forum/viewtopic.php?f=4&t=4881&p=12354#p12354 It has TDR, TDR VSWR, some new calculations and improved live tracking for the graph. Also

Just rec'd my NanoVna about a month ago. Found this group with great info. This is my first comment. Hope it is taking the correct path into the Group's posts. To protect the nanoVNA, I am mounting my

Here are two SWR scans of my ZS6BKW antenna, one with the NanoVNA and the other with my $450 AIM-4170D.

I've ordered a pair of SMA male to SMA female adapters to attach permanently directly to the nanoVNA to protect it's connectors. Hopefully they will arrive before the VNA does. John KK6IL

Mike, thank you very much for your insights. The correct use of a VNA is all new to me and I welcome any and all advice and suggestions! Roy WA0YMH [email protected]> wrote:

Is there a NanoVNA Menu Structure Map for the edy555? I see that OFF/SINGLE/BACK doesn't exist on the edy555 version and CONFIG has appeared. Any others?

No No Roy! You need the female to female adapters if you use a coax jumper to move the calibration plane away from the VNA and to protect the connector on the VNA from physical stress. Attaching a DUT

Hi bammi, I really meant female to female because I always use a short piece of coax (which has male connectors on both ends - like the ones included with the unit) on the CH0 port.? This is the way

True dat! ??

After firmware upgrade you're needs to perform touch screen calibration. If you don't do that, touch screen may works incorrectly. In order to do touch screen calibration, open CONFIG menu and press

Hi, could I please also try your modified software? That's a very nice piece of work you did there. fpliuzzi(at)aol.com

This group has a high enough SNR. Please change Subject when changing topic. Thank you. Ted Antanaitis WA7ZZB

I call BS on that, based on a long career in embedded software development. If NanoVNA-F wants Rune's support, then they should AT LEAST provide him one, FREE.

[ I do not have but am investigating cheap Android tablets for Web-Client (e.g. refurb Lenovo Tab 4, Android 7.1) ] WebUSB wants Chrome Browser version >= 65 for Android >= 4.1

For some reason, edy555_bugfix wouldn't run correctly on my device. In particular, when I hit "back" during calibration, the menu disappeared from the screen. Then when I touched the screen that same

One can never have too many different adapters ?

Any one need 10 female to female connectors that I just ordered without looking first! :-)) :-)) Roy WA0YMH wrote:
