Re: Sysjoint SV4401A nanoVNA
As a P.S. to my last comment (below), from a search i found a reference to yet another version of nanoVNA Saver (0.7.3). On one PC, the SV4401A would not connect (or would crash) just as in the other

Re: NanoVNA F V2 not working correctly
Just out of curiosity...for the H4 the VF is entered as a decimal as 0.82. Is the F V2 VF entered the same or is it in percent? 73, Geoff -->AB6BT

Re: NanoVNA F V2 not working correctly

Sysjoint SV4401A nanoVNA
So i bought one of these on Amazon (SV4401A). They're $150 less on Ali Express, but i don't entirely trust Ali Express -- i've been burned twice by them. The last "burn" was $24 worth of fake coax.
