The dates are slightly different when firmware is installed. I used the firmware dated June 11 (20190611). But when I checked the firmware info inside the NanoVNA it said June 12, so that is what I quoted to you. So we probably have used the same software. Sorry for the confusion.
Most of the NanoVNAs being sold have the older F/W. So there is the question, that many users face, of upgrading the F/W .
Yes, I was very lucky with the Gecko auction. It ended late at night with many of the other bidders probably asleep!
