<\/span> edy555 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. <\/span>https:\/\/groups.io\/g\/nanovna-users\/topic\/51382131#6796<\/a>
Look at the files section on the forum where I’ve placed his original (translated) design notes: <\/span>https:\/\/groups.io\/g\/nanovna-users\/files\/Miscellaneous\/NanoVNA%20design%20notes%20by%20edy555<\/a>
Gen 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.<\/span>
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<\/span>

<\/span>
<\/span>
<\/span> I think the Texas hams Larry is referring to are Milt Cram (W8NUE) and Kees Talen (K5BCQ) who once offered the AQRP Vector Impedance Analyzer kit. The last time I looked that kit was no longer available.<\/span>

<\/span> Which had portions derived from a Project STM32-SDR which was developed by<\/span>
Charlee Hill W5BAA, John Fisher K5JHF, Milt Cram W8NUE and Dave Miller<\/span>
VE7PKE\/VE7HR. The software was released as open source.<\/span>
The STM32\/SDR project has morphed to the IQ32 which is still in production.<\/span>
Charlie and Milt over the years have created some wonderful things.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
