That is absolutely not true. The only restriction for Lithium batteries (or any other hazardous materials) is air freight. Nothing to do with a PO Box being the final recipient. The problem is not at

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

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

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*

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
