Loading Wrong FW version for Nano
Before I screw up my Nano, I was wanting to know if you load the wrong version of FW into say H4 that was written for the H, first can you, and if so can you reverse it back to the correct FW? Gary

Re: Protective Case for H4
Seems to me it needs a lid and space for the cables, cal kit, adapters, etc. Of course *which* adapters is a very loaded question. For the moment the very nice box it came in will do for me.

Re: NanoVNA Saver 0.3.3 or 0.3.4
Try NanoVNA-Saver 0.2.2-1, as far as I know it is 32 bit and an exe is available for windows. It works when the newer versions won't. https://github.com/NanoVNA-Saver/nanovna-saver/releases/tag/v0.2.2

Larry, thanks for the lead. After checking the board etc., looked inside the USB-C connector itself and one of the sides had maybe 3 of the pins smashed and shorted inside. So new connector needed, I

@DiSlord - let me ask you kindly following - your H4 branch fw version string comes from "git describe --tags" which shows always 0.7.1... What would you recommend to put in the VERSION string such I
