Try reloading SanoSaver. I've had to do that several times. Dave - W?LEV -- *Dave - W?LEV* *Just Let Darwin Work*

Unfortunately, I'm not a nanosaver expert, so I can't answer. With that said, if your calibration constants have become corrupt, that might produce some strange errors. Make sure cal is enabled on the

OK, Thanks, but why do I get that error message? I have used this setup in the past without seeing the errors. John G4DRS

Your vna firmware is very old. Update it to the latest version - look in the files section for 1.0.45

I am trying to use NanoVNA Saver with my NanoVNA H4. I have version 3.8 of Saver and the VNA is running version 0.5.0. When I connect the VNA, the sweep limits are set correctly on the VNA, but I see

Alan W2AEW just shared an excellent short tutorial covering this subject: https://youtu.be/hqKLFbNYRZc

Can i characterize my DUT power impedance with a nano vna? I want to dial in our bypass capacitors at the critical frequencies for emc! I tried but it did not not seem to work (cannot recall the exact

Hi! Help! Need link of nanovna-h version 0.8 dfu or how to convert bin hex to dfu gile Tnx 73

The Scale command is discussed in both my edited manual and the Newbies Guide by Martin. Both are in the forum's Files area.? That card slot might work but you'll have to cut the 2 locating pins and

Would this be suitable micro sd card slot to install into a NanoVNA-H4:

This is only true for lossless transmission lines. A real transmission line will have attenuation and you will not see the actual impedance at half wavelengths or multiples of it. You will only get an

Jim's last paragraph pretty much sums things up. A radiating structure need not be resonant (zero complex portion of the impedance) to be an efficient radiator. This concept goes counter to

------------ Why just an even multiple ? *Any* multiple of half wavelengths will repeat at one end of the cable the same impedance present at the other end... Only when you talk about quarter

What matters, in most cases, for a single antenna is the radiated field strength in the far field, in the direction you want to radiate.? For receiving, it's reciprocal, so tuning for max smoke on Tx

I understand the value and significance of tuning an antenna to be resonant. I think I understand the previous post about, quarter and half wavelengths of feedline, resistance and reactance and the
