Is the nanovna capable of showing Simultaneous S11 and S21 measurements in one Sweep, like the DG8SAQ VNWA 3EC ? I think I recall something about this requiring two detectors? Beginner. Neal

Thanks, so the only thing I should do is to multiply the impedance/resistance/reactance values by 6 and they should be correct? Also looks like the attached picture became very low resolution after

Having calibrated to a 300-ohm standard, then why not multiply the measured value by 6? I believe there is a place in Saver for a multiplier or arithmetic. Note in your 300-ohm cal. presentation of

Yep, I found this behavior after FW update... rocker switch change “center” frequency instead of moving marker.. sometimes works weird on my unit and it drives me crazy...

Is there a way to make the NanoVNA show the SWR as close to 1:1 on 300 ohm antennas when measuring directly without an impedance transformer, while still showing correct impedance? I need to measure

As I understand this, if a cable can communicate the phone with a PC, it cannot be used with a phone. A "normal" cable is due for connecting the PC, as a host, with a peripheral, being it a disk, a

Yes the app works fine.

Thank you, I wasn't enabling that flag (didnt see the documentation, moving too fast and assumed the s/w would provide a dialog about any settings, my bad) So the flag is set in the android chrome,

I'm running nanoVNA @edy555 version firmware v0.5.4. Is there the ability to save the state of the nanoVNA over power cycles? I have the battery installed, and I can recall 0-4, but not save anything

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.
