Hi Nick , many thanks for your suggestion. After installing the python 3.7 I modified the requirements.txt ( ptyq5==5.13.2) and the command $ python3.7 -m pip install -r ./requirements.txt works ok

Hi Bob, I develop using Python 3.7 - I'm keeping back from upgrading to 3.8, even though I probably should, because of all the problems of particularly Linux distributions not keeping up with stable

Hello Nick, I went back and re-read your post and sure enough explicitly adding the version number to PyQt5 in the requirements.txt file fixed the issue for me. Many thanks for taking the time to sort

Hello to all who have replied and all the hints have been really helpful. I have installed python3.7 using the deadsnakes ppa with no problems there and have loaded pip3 from the Linux Mint

============================= Graeme, you are perfectly right ! Adding my user to the dialout group eliminated the need of running under sudo. TNX Alberto

Nick Thanks for posting. Your suggestion to edit requirements.txt worked perfectly for me on LM19.2! First a quick look at pip3 version.... den@den-ThinkPad-T520 ~/nanovna-saver $ pip3 -V pip 19.3.1

Larry and Oristo have put in a lot of time and effort assembling information in the Files and Wiki sections of this group. For whatever reason the same "What is the correct calibration procedure",

No - freq range is 50KHz to 1.5GHz on ALL NanoVNA units, except some cheap Chinese copies that were not built well or had shields. Read the hardware section of the Wiki. ALL NanoVNAs sold were a

Thank you,

I am running Python 3.6 with 32-bit Ubuntu 18.04 and it does direct Python interpret (not compiled) of nanoVNA-saver version 0.2.1 without problems, as best I can see. In playing with this, it appears

USB4 uses the same connector and is backward compatible. It is essentially a more open standard version of Thunderbolt 3, including that standard's USB compatibility and use of the USB-C connector.

I was a pretty early purchaser. The cable that came with mine has always been flakey. It's now become completely unusable. I finally went down to Target and bought a cheap replacement cable (I think

Hi Graeme Sorry to hear that you cannot get nvna-s working on LM19.3. Same setup works fine here. https://github.com/mihtjel/nanovna-saver At what point does this install process fail? What are the

Another problem with the demo board U.FL connectors is that they are surface mounted and unless you physically hold the connectors down while disconnecting cables can easily detach from the board.

I concur with these statements though I have managed to get the connectors mated but with some great effort and care. *Clyde K. Spencer*

You need a slit screw driver about 5 mm wide. Hold with one hand the female connector of the cable centric over the male plug on the board, and press with the other hand the female plug with the screw

Just be aware that the connectors used on the board are not made for repeated connect/disconnect and will not stand up to repeated connect/disconnect. Cables need soldering to prevent breakage .

Yes, those cheap U.FL plugs are a challenge to seat. I use SMA to U.FL adapters. Example is from Centric RF C9917B - Adapter U.FL/Plug S<A-Female (U.FL/AMC compatible) S Steel 6GHz VSWR 1.3 The

I have a question, from what I see. the problem seem to com from debian flavored distro. Anyone can report what version and linux distro they are using where NanoVNA-saver works right away? I am
