Re: NanoVNA App - Installation and Use

ya, that's what I am thinking to, I can load stock firmware back if you need. I did post in other forum too. I can use the nanovna.app to load firmware it does detect when it's in DFU mode, so I would

As i know all (but not LCD module) work, you always can load last firmware from official page for restore. https://nanorfe.com/nanovna-versions.html

Ok that's is good to know i will ask them. you was saying about the display unit could be newer, what would happen if i load your firmware onto a "new" display model? if by doing that the display has

I do not track the development of these devices, the developer asked to leave support. Therefore, it is better to ask him on the site /g/NanoVNAV2 Firmware for the device that I have

Re: Antenna Gain measurement with NanoVNA
Seems to me you are conflating reactance with resistance. 0 reactance by definition is the resonant point.? Has nothing to do with resistance or VSWR directly.? Resistance and subsequently VSWR are

Hello Everyone, I was wondering has anyone of you used this product? (https://www.ebay.com/itm/234166377165) My concern is whether this VNA can talk with nanovna saver or may be with some python

Re: Antenna Gain measurement with NanoVNA
I keep seeing the statement that a resonant halfwave center fed dipole has zero reactance at the feed point, and I don't think this is always correct. For a center-fed dipole that is 1/2 wavelength

Use ST-Link programmer, see /g/nanovna-beta-test/message/3109 Part dump firmware. Most easy see current version on version screen, and just download current firmware from official

I agree with you X: gain of antenna 1 under test (what we are looking for) A1: gain of antenna 1 A2: gain of antenna 2 M13: measurement of link 1 to 3 M12: measurement of link 1 to 2 M23: measurement
