Some people need one simple functionality from NanoVNA, others need another simple one, and so on. And what to do with many simple functions for each? NanoVNA interface is quite simple, and it is

Just a thought - there are several apps for Windows and Android that could meet your needs for an easier to use interface. Most will run on an inexpensive tablet or Win PC ($100 low cost

Thirty-one posts ago, back on December 23, a guy with a NanoVNA-H4 asked for help using it with an Android device. I assume he wanted to make some network measurements, possibly for communications

Jerry, Have the last word. I['m done here since you're resistant to facts. -Rick [email protected]> wrote:

Hi No problem to consider that , transceiver should be happy with a real impedance load 50 Ohm indicated by its internal SWR =1/1 , and the 75 Ohm Coax should be happy with a 75 ohm antenna load

Rick, You seem to be stuck on the idea the API is the only thing involved. My point is that sometimes there are changes in the kernel which affect the libraries. That is why sometimes you have apps

Exactly that, the Tx circuitry cuts back on the output power as a result of the reflected power on the transmission line, and that reflected power is quantified by the VSWR (or return loss) due to the

No mention has been made on a lot of the installs as to if they installed via the store, or an apk. The store looks at device type (tablet, phone, etc.), Android version, and perhaps other things to

Jerry, You're stuck on this point but it's simply not true. It's not the kernel. The issue here is the API level used to build the app. That's it. It's the API level. When the Play Store says that an

Sure, I'm an engineer. I've been using professional VNAs for some 40-years. I salute the creators of the NANOVNAs! It works just like the professional units and quite intuitive to me. Keep it up. I

Well, first of all, Linux is only one OS out there, so it is not really a great reference. There are many other OS's out there, several of which I've worked on, from embedded systems to mainframes.

Great references, thanks!

Maybe. It kind of depends on the amplifier - some just fold back when the voltage at the output terminals gets too high (to protect the transistors). That is, the protection circuit on most amps does

OP: Your thoughts are legit, but you will face lots of opposition from existing users and from the developers, as these VNAs are designed to have every possible feature and are built to perform just

You'll probably get along much better with a RigExpert analyzer. I use this one: https://rigexpert.com/products/antenna-analyzers/aa-230-zoom-option-ble/ and I think it's what you're looking for.

A developer named Reald did make a big font version with SWR display about 4 or 5 years ago and you could try that out and see if it works for you. The links are in archive posts. A simplified menu

Yes it is the transmission line that has the standing waves on it. However as I stated in my previous post the transmitter power amplifier is designed for a specific load which is 50 ohms for ham

Yes, it is not labeled 'TDR' in the menus. Instead it is appropriately labeled 'Transform', since it is not a true TDR, but simulation of a TDR via Fourier Transform. On the menus: Display ->
