Re: Jog wheel switch causes problems #parts
Folks, Always read the release notes for the version and development release of firmware you've flashed your device with. In this case, edy555 documented the jog switch changes at this link:

Re: connectors grounding
well looking at the link to owen duffys solution it looks like the ground is common to both connectors then?,cheers all 73

Re: connectors grounding
i think you missunderstand me,on nano the pcb it looks like the body of the sma connectors ie the ground are not electricaly conected to each other,thats what im' trying to find out.ie is is important

Re: HI-Z EVALUATUTION - MEASURED DATA COMPARISON with HP 8753C
Here is another similar set of data: http://www.janbob.com/electron/466R2VNA.gif I think it supports Dave's general conclusion for resistors like 470 Ohms. This was done with a HP8714B VNA that is

Re: connectors grounding
Shields must be connected as should the center conductors of any cable extenders. Highly flexible cables are a good method to embody a connector saver. Be fure to use good quality cables and

Note, with clearer screen captures: 50-ohm cal: S11 reads 304.88 ohms real as a folded dipole shoud (on the right of the chart right where it sould be for 300- ohms real) 300-ohm cal: S11 reads 53.5

Re: Android app cable not working!

connectors grounding
Hi all,just a quick question,i notice the sma connectors on my vna are fragile where they join the pcb,i have some beter ones,i thought of fabricating a piece of copper sheet and mounting them on

Simultaneous S11 and S21 measurements ?
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

Re: SWR on impedance other than 50 ohms #measurement
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

Re: SWR on impedance other than 50 ohms #measurement
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

Re: Functions of the rocker switch
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...

SWR on impedance other than 50 ohms #measurement
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

Re: Android app cable not working!
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
