I think you will find this video by W2AEW on measuring crystals with a NanoVNA interesting. His videos are technically accurate, easy to follow and quite informative. He uses an earlier version of

So far what I have is CONFIG, SAVE saves: Touch screen cal Grid color Trace color Flip display CALIBRATE, SAVE# saves (per #): Frequency range Sweep points Calibration Error Correction Trace settings

Joe, I suggest you read the Absolute Beginners Guide to the NanoVNA. Your question and many others that new users ask are described in detail. It is in the files section of this group.

Same answer to both questions: yes, saving in 0, 1, 2, 3, or 4 lets you open that calibration any time using the RECALL command. And if you set up all the traces you want during a calibration, and

Thanks! Now does this recall all the stuff including the calibration etc.? Joe WB9SBD

Recall menu Allow recall saved calibration slot

I add this feature for all H/H4/V2/V2Plus in my last v1.0.69 See Marker->Measure menu Unpack and use firmware for your device variant

Joe, The prior save-1 action will keep 1 as you set it up. That is all cals, freq range, display etc... But, if you decide that you do not like some item in 1... as long as you do not significantly

Ok, Good, Now if I was to save to Save-1, how does one use save 1 in the future? Joe WB9SBD

Save to location zero everything like cal and displays will boot to all saved items. You can do the same with all other locations. But, requires a recall after turned on.

Hi Joe , you have to save 0 . When you turn on the nanovna , by default the register number 0 is recalled. Maurizio Iz1MDJ

I recently joined the club and bought a NanoVNA, which I think is a "classic" version clone (no case, no shielding). It is currently running NanoVNA-H firmware 0.4.5-1-efbbceca. My current goal is to

When you do a calibrate. Open Short Load, And then Save, I usually save 1 What is this saving actually doing? Can you retrieve this Save for future use? Speaking of a save. say you make changes to the

Interesting how a little DX35 with its small output tube would provide a similar set of L taps for the pi net as a pair of big bottle 3-500 Z's. Apparently the ratio of plate V to plate I and the fact

I took my old DX35 tank coil that has multiple taps and my Mosley traps and they pretty match your Now is values. Here is your now is: 10 = 1.1uH 15 = 1.8uH 20= 2.94uH 40= 6.46uH 80= 12.46uH Ps I used

You have to change the stimulus range I ended up for my coils 1-8 mhz then 10- 30 mhz an then a narrow span. Also I didn't recalibrate just to see what would happen. Down in the HF region results were

If you’re looking to refine your measurement repeatability, do a fresh recal, repeat the sweeps of both induntors under as near exact conditions possible, then recheck your cal to confirm

Joe, Once you have measured and installed the coil and capacitors in the RF Amplifier you can tweak the settings to compensate for stray capacitance and inductance by measuring the 50 ohm output

Well, I left the coils in place in the amp, BUT.... I lifted all the taps, so the coil is floating free but inside the amp. And all readings are normal now. Interesting. So OK we planned on leaving

The rotations on the Smith chart generally imply of resonance. The resonant frequency is where the trace crosses the real axis. It sounds like you may have moved the SRF inband. Don’t change your
