Hi John, It cannot be the same because there are differences in size. Previous edy555 versions and their contact details are in the pdf below. Important: Only available for 2.8 "nanoVNA versions. 73,

Many 50 Ohm loads are made with two 100 Ohm smd resistors in parallel. I've seen many loads fail after intensive use, all the sudden they are 100 Ohm when connected. Unconnected 50 Ohm. We solved it

It looks like the hex file in the zip collection is the new version, but the bin file is the 0.7.0 version! --John Gord

I found the problem. My 50 ohm load was OPEN. I don't know if it can be opened to solder something inside. But tapping it on the table made it work again. So weird.

edy555 has released firmware version 0.7.1-20200321 for the NanoVNA. No major changes from version 0.7.0: Contributions from @DiSlord - shrink flash size - faster sweep - added color command Added

Hello Gianni, For my 2,8” NanoVNA I bought a 3,7 V 750 mAh LiPo battery from Electrokit. It is larger than the original battery but thin enough to be placed sticking over some of the components. As

Thanks, will try that

Thanks.

Alex, I have seen this before when I forget to reset before calibration. Press RESET twice to clear the current cal tables and then recalibrate. Roger

There have been some reports on here of new NanoVNA-H4 devices having similar issues. Some have found loosening the case screws takes pressure off the LCD screen and then it works. Rather than repeat

NanoVNA-Saver.? It's awesome, and runs on both Linux and Windwoes.

Is there a way to do a system reset. You know - hold something down, stand on one foot while smiling?

I hadn't calibrated my nanovna for a while and today have discovered it acting strangely. Before when I finished calibration the open read on the far right of the smith chart, the short on the far

Use the jog wheel to select CONFIG in the menue, then calibrate the touchscreen.It's a resistive touch surface so you'll need something like a Qtip.

Hi all. I just got a new NanoVNA-H4 from GigaParts. It wasn't sealed so that is a red flag to me. However, everything is there. When I turn it on I see the intro screen for about 10 seconds and then

Hi Robin, You have 4 options here: 1. buy the newest 3.5GHz unit 2. use your unit with either a tablet, phone or PC via USB 3. check to see if a solder pin on the LCD's ribbon cable got cracked and
