Bruce, I added the full Goggle translated user guide (NanoVNA_manual _ch045) to the "Files" section of this group. Again, full credit and appreciation go to Hiroh Satoh's (user "ch045").

Ok, thanks I'll focus on transmitting then as it generally goes that an antenna thats good for transmitting on a certain band will also receive on that band ;)

John, The first step before performing the OSLT (Open-Short-Loa-Thru) calibration is to select "RESET" under the CAL menu. Neglecting to do this can result in the -10dB offset you are seeing.

@Reginald Beardsley via Groups.Io : /g/nanovna-users/message/2927 /g/nanovna-users/message/2948 Hello, Allow us, please, to point out that frankly we are not sure if

the only issue that I have with NanoVNA bought on aliexpress is the switch (joystick). It seems that I got defective joystick, because it is often triggers push when I'm trying to make right turn. The

I bought the NanoVNA from eBay - not that it makes much difference. Lithium ion batteries can fail with catastrophic consequences. I know that the switch on the NanoVNA is of appalling quality, but I

I bought NanoVNA on aliexpress in this store: https://www.aliexpress.com/item/33016805196.html It comes with battery - 602040 3.7V 450mAh. The battery includes protection module. I tested it, NanoVNA

David, yes, SWR (resonance) is fairly pertinent for an antenna. But once again, this does not say, if this is a good antenna or not. Efficiency = good antenna is a matter of antenna gain and resonance

@erik@...: /g/nanovna-users/message/3008 Hello, First of all, allow us, please, to express, on the occasion, our deep respect for your impressive Work with NanoVna. Next,

Hi John, thank you very much, and thank you for the kind description in your linked post :-) I assume you've calibrated on the NanoVNA? Or did you make an in-application calibration? Either should be

Not necessarily. A dummy load will have a good match - maybe even perfect - but does not make for a good antenna.

run Rune's application. All others skip over this post. permit an observation on the Linux systems of interest here. Even if you understand already, others less familiar with Linux may be helped. in a

I'm in the UK but i can use antenna as well, same thing ;) But the Nano can show the resonant frequencies of an antenna and that is fairly pertinent to how it would perform ?

David, with NanoVNA you can not find out, if an antenna (think you called it 'aerial') is goo for your purpose to receive signals, or not. Depends on your receiver, if it has an input impedance of 50

Hi all, I have a NanoVNA, great little gadget, I'm interested in in aerials, at present for receiving only. What would be the best output to look at for this purpose, i think its going to be S11

Rune, many thanks for developing this software and making it available to us all. It *greatly* increases the enjoyment of using and learning the nanoVNA. I went through the full 2-port cal yesterday

Dr. Kirkby, it does confuse me a little why you would buy a VNA from AliExpress, but not a battery from Amazon. ;-) As long as ones expectations are correctly set - namely, to receive a battery of an

I would *never* buy batteries from eBay, AliExpress, Amazon or similar. Just buy from a reputable distributor of components for the *professional* market. In the UK, I would use Farnell, RS. Digikey

My battery started swelling after two charges. I am afraid it could explode or damage the nanoVNA due to the pressure. I will change it as soon as possible. Bought at AliExpress Guangyi0016 Store.
