David, The meaning is the upper limit is 100 MHz higher than the 900 MHz of the NanoVNA-F. Herb

I am unsure if you made a typo or an error, but on the link to alliexpress, it shows a marker at over 400 MHz. Did you mean 1000 MHz rather than 100 MHz? Dave -- Dr. David Kirkby, Kirkby Microwave

Rune, do you want feedback here or via email?

Fair questions. My use will be 99% lab use. This means that form factor is not important. A display is nice but not critical, and if the display is less than 7" it is more or less useless to me. I

David, It would interesting if you gave a review of the NanoVNA and NanoVNA-F since you own both devices. Especially interested in whether Rune's nanovna-saver app works out of the box with the

You need to be connected to the Internet in order to use the Web interface because you need to access cho45's webpage.That means mobile data or WiFi. All I did was to connect my nano to the tablet's

Normally, you really don't need to upgrade if the device is working well for you. Typically, one would upgrade for two main reasons: 1. New functionality 2. Bug fixes The latest edy555 release fixed 3

Hi Nigel - It's good when a plan works. I have little Windows 7 experience. (I found Vista so awful that I pretty much stuck with XP SP2 until 8.1) Firmware updates almost certainly require STM's

From: Dr. David Kirkby from Kirkby Microwave Ltd Rune's NanoVNA-Saver looks a lovely bit of software, but it is not much good unless you work outside, unless willing to take a PC worth you.

Up until now, I have used my $450 AIM-4170D for measurements made inside the shack and it is capable of being calibrated to make remote measurements from the shack. Calibrating for those remote

Hi Bryan, sweeping currently works as follows: 1) The requested frequency range is set (start and stop frequency) 2) A delay of 300 ms 3) The frequencies are read back by sending the text

Good afternoon from sunny South Africa :-) Updates: Rune - Copy of log file(s) created below FYI but not much to analyze... Also a screen shot of the command window and log file from a USB 'trace' in

I agree. How about a soft-switch to enable external communication either through the USB port OR a serial port that could be connected to a Bluetooth Dongle? My 0.02 ...Larry
