If your phone has a micro usb port then try an adapter like this one

Thanks Herb I must have missed that. This time, I went to your web app online with my samsung (j7 prime) and still "no compatible devices found".. This is the cable (below): I am not sure what to try

Kayak, That's one of the ones I got but it didn't work with my phone. -- Chuck, W5USJ

Herb, That may be the problem I'm having. Tried two different cables and NADA... My phone is a micro type so I got USB-C to USB-Micro/M -- Chuck, W5USJ

Hi When opening your link to the USB cable (s ee copy below) in the German Amazon store it does NOT state "OTG" capability. May that's helpful info? USB C to Micro USB OTG Cable, CableCreation 0.65 ft

When I (try to) move a marker on the Nano screen (not PC) the jog wheel switch causes problems. It is too sensitive and starts to change frequency settings.

In calibration for measurement and in measurement at RF frequencies, high-Z is far more difficult than a short or proper 50-ohm termination. Take 144 MHz and assume you are attempting to measure 1

I'll tell you what I have done to test high impedance RF. I built myself a fixture PCB, you can see if here: https://github.com/profdc9/VNA/tree/master/fixture One of the parts of the fixture PCB is a

I'm a happy camper. Got the Hugen firmware flashed, ordered a 100 count pack of diodes from Amazon via next day Prime delivery and as of last night, I soldered one of those bad boys on and I now have

My tube amplifier takes exception to your statement: "High Z is hard to obtain at RF. " The amp wants to know who do you think has been talking on 40 meters for the last 30 years? And the 450 ohm

Got the cable today, did NOT work. This is number two. This cable is an OTG data cable USB-C (nanovna) ti Micro-USB (samsung android phone) NanoVNA Web App from play store says "no device found" when

High Z is hard to obtain at RF. For parallel twin lead with #16 wire, the spacing is 0.3 inches for 300 Ohms. The spacing for 1000 Ohms is 105 inches!

for 144MHz in HP8753C column you have a typo I think... -- Regards, Slawek/SP9BSL

Sorry your table is all over the place can work out which is which. Go higher than 1-2K ohms, think you will start to see the difference.

A few weeks ago I decided to measure S11 of a few metox wire ended resistors and got the following results at 10 MHz. Nominal value Rp 50 50.5 100 99.85 180 181.7 270 267.9 390 386 470 466 1000 986 I
