Ok, got it Warren. Thanks. I guess at this point, I have used the PC Sharp program just for reading the VNA contents. Not for calibration. And the only cal routine I have used to date is whatever is

I've just ordered one from evertech666 on eBay (?38.99). It has the improved screening etc. I'll report back when it arrives. 73, Leon G1HSM

George Hmmmmmm….. I guess I don’t see it as a problem. More of a “feature” in my mind. I am using the 900 MHz, two trace firmware and the app V1.31. What upgrade am I missing? WA8TOD

Hi Alan I am referring to the NanoVNA V1.31 app that is zipped into the downloaded firmware bundle. At first I thought it was just a remote monitor for the device touchscreen but it seems to have its

As I understand the firmware, it interpolates between the calibration points. But I do get some absolutely horrible results around the frequency where it transitions to using harmonics (270MHz for my

Warren, this problem was fixed in one of the early firmware upgrades.

Hi Rune. Your contribution to the nanoVNA community is really appreciated. I have a question for you. When you divided the test frequency range into multiple sweeps to increase resolution from 101

Hi Warren, Just to clarify. App vs. Device. I probably missed the definition of App... I assume that is a PC comm with the VNA while the Device is operating the VNA directly from the touch screen?

One quick correction. If you Recall0 from the app the legend on the device will change from “C0” to “c*” indicating it is no longer internally calibrated. WA8TOD

I am not sure this has been noted before and if it has I apologize. I have noted that the calibration values saved and recalled in locations 0-4 are different on the app than on the device. In other

thank you, i have experience shipping equipment designed for installation in commercial 19 inch racks both domestically and internationally. suffice to say the equipment weighed a great deal more

@carsten it's not a "phone" any more, for this purpose it is a single board computer. the Bird engineers create the firmware to load onto it, therefore the Android update schedule is a non sequitur.

He may need to a install pip first...not always installed with python. Frank --- Frank M. Howell, PhD Ridgeland, MS frankmhowell (at) hotmail.com ---

The file to run is nanovna-saver.py. You need to have installed "PyQT5" and "pyserial" first - I *believe* you can run "pip3 install pyqt5" and "pip3 install pyserial" to do so. Maybe Marcel can

Hi Rune I am not familiar with Python but I will give a try I just dowload the Python Software for the MAC and Python is working. Which of you files shall I start? I would like to thank you for the

Thank you Rune! Will be checking it out too. 73 KC2ISE

Very nice job! Tried on a windows 10 (64bit) and running fine. Marcel

Not really - for a dedicated piece of test equipment, the intent of the design is fine. Nowhere in in manual is a guarantee that the device will run end-user apps. Most end-users will use it with the

Great job! I will beta testing it for sure! Cheers, Luis, CT2FZI

My Hugen NanoVNA arrived day before yesterday. No issues, the packaging seems to have held out well. Haven't tested it yet. Den s?n 18 aug. 2019 14:29Hans J Albertsson via
