Re: NanoVNA V2

Re: NanoVNA bricked
I finally got mine unbricked using "conventional" methods. Here's the story: 1) Used ubuntu dfu-tool to load CLEAR_MEMORY_DFU.dfu . That left the NanoVNA white screened. 2) Tried to use dfu-tool to

Re: Cal-Kit Standards' Definitions

Re: Cal-Kit Standards' Definitions
Hi Jim, You are essentially correct, but I was thinking more of Rune's Nanovna-Saver application (which allows the user to specify C0-C3, L0-L3, and delays for the two) rather than the NanoVNA,
