Hi I flashed this firmware into my NanoVNA-H4 and itworks ! .Anyhow it works normally under NanoVNASaver. ? In the menu I see several addon's but these are not (yet ?) supported by NanoVNASaver

you mention the schematic - can it be seen somewhere online? ============================================= Marko, The attached file is the version 2_2 schematic provided by Gabriel. - Herb

Hello Herb, you mention the schematic - can it be seen somewhere online? I will definitely buy this, but I can not do it currently from Tindie, not shipping to Slovenia (in fact, there is a quite long

Thanks for trying to help, Tom in AZ, but what good will it do to study hundreds of hours to try to make sense of that one line? That is, I do not see on the chart any markings that allow scaling

There several tutorials in the files section, I've spent may years in electronics and I still need a refresher from time to time. Read the tutorials and it will clarify Tom Sides KI7FTK skype: Thomas

Aldo, in your tutorial is said: Would you please explain where these values are seen? Thanks!! -- I_B_Nbridgema

Hi there, Do you think a specific groups.io group would help? I have created one already, as I am waiting for my unit, but I am not sure if its impolite to mention it here. *73 de Luís, CT2FZI*

Or an amazon drop box if one is not far away. They are all over the place. The local Rite Aid, Ralphs,? UPS Store and health food store all have them within two miles of me. Eric KE6US

The problem with P O Box is the battery in the VNA. PO rules prohibit a lot of things that burn and record how the parcel was shook in transit. Amazon follows the rules, but some of the flighty others

OK I am trying to order it but turns out they don't send to US PO Box addresses which in this case is my only practical option. Why in the world would you put such a stupid restriction on this small

Gabriel, What program did the team use to simulate the PCB with the various components? I want to simulate (initially) some lumped component (SMD L and C) filters till 1GHz on a double sided FR4 PCB

That sure makes for some mystery, Gabriel! Why do you use a pseudonym? Randy NC8U

I have now made up my NE602 mixer circuit on prototype board and have tested it again using 1 to 8 turn transformers and (as suggested by Roger above) 1 to 7 transformers. The nanovna-saver images

At lower frequencies, the NanoVNA 2.0 uses the same chip as the version 1, an Si5351.? So, the output level will probably be similar.? At higher frequencies it uses an ADF4350, which has a rated
