Yea I understand completely as it is the same for me fumbling with it a bit. My unit did not come with a “through” cable so i ordered one from amazon as well as another OLS kit. One of the tests

Vince, I got the nanoVNA_900_aa_20190802.dfu firmware installed on the device. I figured out how to connect the boot and VDO ports together to put the device in DFU mode. Hopefully that's the right

Hi Jeff, Open has a hole Bronze is short Silver/white is load. You will also need another load and a through cable to complete the calibration completely. You can pick them up on amazon. Vince

My second unit arrived today. I intentionally ordered the white, salamander, "worst" unit as a complement to my black "worse" unit. Loaded up the 900AA firmware on both and calibrated both at 50,

In case you haven't already worked it out: aa firmware is a 2-trace Antenna Analyser version, which uses a larger font. 800 versions go up to 800MHz rather than 900 and are a fix for users

Thanks Mike! I'll do a little more RTFM on the firmware releases. :-)

Hello Rune, Yes, the S11 curve and Smith chart looks the same in the LCD. I have just a 50 cm coax cable RG316 connected to the TX port. Strange. 73, Rudi DL5FA

I'm stumped. I've had similar errors before, but I don't know what the right solution is. I hope someone else on the list is able to help. -- Rune / 5Q5R

You should be able to put the serial port in the input box, so you don't need to edit the code. But changing the code means it saves it ;-) The dots vs. lines is a matter of how many sweeps you ask

Hello Rune, Thank you very much for the nanoVNA program. It is a prosmising start. It works also under MacOS Mojave 10.14.6, see the attached screen shot. You just have to edit: self.serialPort =

The silver one is the load. Sent from Mike's iPhone

Hello! Sorry for the n00b questions.... I just received my NanoVNA last night. I’m looking at the Google Drive folder and I see two firmware files with “aa” in the file name. One has “800”

I have python2, python3.5, and python3.5m -- I'll see what else I might be able to get for Ubuntu 16.04 ... Thanks

I've developed it using Python 3.7, and the typing (": List[Datapoint]") in that line is reasonably new syntax. So you may need a newer Python version. I'm not a Python wiz either, so I couldn't tell

I'm not a python wiz, but when I try this on Ubuntu 16.04 with either python or python3 I get: File "NanoVNASaver.py", line 49 self.data : List[Datapoint] = [] ^ SyntaxError:

I used to laugh at the way the military would pack parts and equipment for shipment, but long ago I learned the reality of how packages are handled in the real world.? Some companies would put an

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
