I looked but did not see this question asked yet. I decided I want the 4" screen. It seems both the NanoVNA-F and NanoVNA-H4 have a 4" screen and have similar frequency range, but I'm having a hard

Tim, I fixed my H4 by slightly loosening the case screws, as suggested in some posts. I shared the success with GigaParts, so they can relate that to other customers. Now I’ll join you on our

Hi Les, What did you buy - the H or the H4? Some of the early H4 units had problems with the housing pressing on the touchscreen. Loosen the housing (4 screws) and then see if you still have the

The STM32F303 does not support OTG.

Tim, I got mine from gigaparts this weekend, and it boots up to a copyright screen, and not to a Smith chart. Did your get beyond the copyrights? Tasha Sandlin at Gigaparts told me to go to this forum

Dear DisLord, A quick question, would it be reasonable to support USB pen drive via OTG? Thanks!

Welcome to the group. In addition to the above, I also recommend viewing my website. 73, Gyula HA3HZ -- *** If you are not part of the solution, then you are the problem. ( http://ha3hz.hu/ ) ***

I have to disagree with that. The extra size would be of no practical consequence to most people if a NanoVNA was in a larger case suitable for N connectors. The small size and battery operation makes

For a small device like the NanoVNA an N connector is simply too bulky. It's not relevant for NanoVNA frequencies, but SMA connectors offer significantly better microwave performan

Hi, Have a look at Alan;s latest videos, they can put you in the right track. (..invaluable) -> https://www.youtube.com/user/w2aew Also, have a look at group's wiki for all kind of information ->

I am a new NanoVNA owner and have received my unit through GigaParts. For a new user who has a device that comes with close to zero instructions the list looks like an incredible resource but is a bit

Be aware that very few receivers have 50 ohms input impedance on the RECEIVER. Years ago I decided to measure some of my radios and it was an eye opener for me. I always ASSumed that all my ham radios

Hallo zusammen, inzwischen habe ich mir dieses Hilfsmittel angeschafft: https://www.sdr-kits.net/testboard-full Diesen Hinweis findet man auf der Seite von DG8SAQ:

NanoVNA and NanoVNA-H use some firmwares See /g/nanovna-users/message/14450 You can use edy555 firmware from https://github.com/ttrftech/NanoVNA/releases Or you can use my variant

It is recommended that you use the firmware compiled by DiSlord. /g/nanovna-users/topic/nanovna_firmvare_compiled_by/73181877?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,73181877

Hugen, How often is firmware updates available for general use? Seems to be that H versions are behind several months.

Normal SWR range is 1 - 3 Y Grid lines on screen = 8 Default scale is = (3 - 1) / 8 = 0.250 You can change trace type, scale, and save after calibration. After load you get them all on display.

You can buy it from R&L Electronics. R&L Electronics is temporarily out of stock, and the next shipment should arrive soon.

Looking at purchasing a NanoVNA H4. Where is the best place to research what the meter will and will not do? Second where is a honest place to purchase one that’s fair and not a knock off? I have

No, it's math done on the complex S11 parameter. 73, Carey, WB4HXE -- Carey Fisher careyfisher@...
