Patrick,
Please browse the forum Wiki
/g/nanovna-users/wiki/homeedy555 is a Ham located in Japan and essentially took an existing idea from a couple of Texas Hams and developed sophisticated software and created a kit for the original NanoVNA and opensourced all of it.
/g/nanovna-users/topic/51382131#6796Look at the files section on the forum where I've placed his original (translated) design notes:
/g/nanovna-users/files/Miscellaneous/NanoVNA%20design%20notes%20by%20edy555Gen Hu (hugen), a Ham in China then took edy555's design and improved on the software and hardware and began selling them as assembled devices on the TaoBao website.
Soon, a pile of copies/clones appeared of hugen's design.Now, version 1 of the NanoVNA hardware which tops out at 1.5GHz is mature and edy555 & hugen are working with others to design NanoVNA V2 that will go up to 3GHz. In the meantime, another developer created the NanoVNA-F with a larger screen but tops out at 1.2GHz
You really need to go through (all 8000) forum posts as everything you need is there.?
RegardsLarry

Gentlemen,
As the editor I would like to write an article for the Tacoma Radio Club's newsletter including the history of the development of the NANO-VNA. I would like to include the names of the designers/developers and software developers as well variations out there. I have been unable to pin down very much of this information after several hours of internet searching. Who is edy555? Who is Hugen and how is he involved? What is the involvement of Rune Broberg; software only? Any others I have not come across?
Would someone on the list please pass along the history to me; I would much appreciate it.
Thanks,
PJH, N7PH
