The only part of the Smith Chart that is purely resistive is the center horizontal line. Upward is inductive and downward from that line is capacitive. That's the advantage of the Smith Chart. Since

Make sure you are using an OTG Cable that tells the tablet to become a USB host. You can verify its in host mode if you're able to read a usb memory stick.? On Mon, 20 Jan 2020 at 6:06 PM,

NanoVNA-H4 updated Firmware to the latest version as follows. All right! ChibiOS/RT Shell ch> version 0.4.5-12-gea578a2 ch> info Kernel: 4.0.0 Compiler: GCC 8.3.1 20190703 (release) [gcc-8-branch

NanoVNA WebApp connects to my worse clone from Galaxy Note8 Android 8.0.0 as does Serial USB Terminal by Kai Morich a SMAYS powered hub connects by type C to Note8, and to NanoVNA by Type A to C

Really? I have used this method for years on a bunch of different Linux distros. Hold down Alt, left click and drag the window any way you want: up, down, sideways, whatever. Something ain't right

Thank you, thank you, thank you. Your instructions worked FB on Ubuntu 18.04 -Ed

Thanks Herb. None of my units will connect. Will try the on-line and see what happens. Would be nice for field use though with my phone. Merle

This is a good tip. Just remember that the feedline is only a multiple of a half wavelength at one frequency. If that's the center frequency of your antenna then the impedance at the end will be the

Thanks for the responses. The trick of using alt + left mouse only allows moving the window down. There's also a mini-menu if you right click the title bar of the panel with some promising sounding

Quite a collection Merle, Are either of your other two NanoVNA's able to connect to your Samsung Galaxy 8+? If so, then the nanoVNA-H4 should be able to connect by the same means. If not, then the

Oh! I should add, just for completeness, 1. After the antenna is matched (near 1:1 SWR) feed-line length doesn't matter (up to the point where matched-line loss is significant), and 2. Wind coax thru
