Too many things don't work as they probably should so returning mine. I expect I might just have an odd unit? I will tinker with code based on the original github though as this has also got me into

I had the same from panda201898 but it turned up a couple of days later ... very disconcerting though

Hi all :) On good news I have NanoVNASharp running under Linux ... bit of a play and got there ... But cant get the com port to forward through .. A problem lots have and i am sure when I am more

Is anyone else trying this out .. My experience so far: OMG the Com port is not being detected ... read loads of crap on STMicroelectronics Virtual Com Port from ages back ... then noticed instead of

Bob, The charging circuit is part of the 3.7v to 5v inverter. I soldered (welded ;-) ) an old Motorola really thin cell battery to mine and it charges without issue. Q: when you apply power via the

Folks: Regarding batteries, I ordered mine on Banggood, and the description contained this caveat: * Batteries are not included because of the safety of international transportation. But we have

While playing with NanoVNA Sharp (1.02), I realized there are no marker functions. Do any of the SW people know if markers can be added? Thanks Frank

I wouldn't worry too much about the message "This user is no longer registered on eBay". Often the cause of the message is the seller hasn't paid the fees that are due so ebay suspends the account.

The firmware I compiled has been optimized for the touch screen of my hardware，Download to to other hardware may require recalibration. You can use the shell connection and calibrate via the

Hugen, I noticed that the accuracy of the touchscreen is not the best. I was going through the NanoVNA GitHub source and I saw a few calibration and self test routines in control.c . Do you know how

There's no plan for open source nanovnasharp in the short term. The 900M firmware will comply with the gnu License and open source after fixing some errors.

Dear Gen ( i hope Gen is your first name) Glad to meet you in this forum. Have you planed to make this C# software open source ? I have the same question for the 900MHz NanoVNA

I've pushed both the nanoVNA_900_AA_20190611.dfu and nanoVNA_900_ch_20190505.dfu firmware to my 'Gecko' VNA and have found that they were compiled by gen111.taobao.com as that URL appears on

I would check ALL the solder joints. I thought I got ripped paying $75 for mine, but maybe a better manufacturer :-) It's all Chinese junk

Thanks Frank, I will take a look at the usb socket soldering. Perhaps that is the issue? 72 Dom M1KTA

I connected it to a USB cable and turned it on, nothing. Pulled the USB and there it came up. Plugged the USB in again, and was able to get it to connect to Nanovna sharp (v1.20). Running it in auto

I hooked mine (White Gecko) to a tunable filter (63 to 125MHz) and I was impressed with what I saw S21 and S11 looked lit was when I swepted it at work. I was recently?? laid off (retired?) and want

It will detune hi freq stuff. Having worked in RF from the KHz to GHz, I know it effects sensitive circuits plus it picks up all kinds of crap. Better off cleaning it off with alcohol then blowing it

Tried the gecko version with various different USB cables that do work with phones and other electronics and do NOT see the board either under Linux or Windows. I might try with an ICSP header. So
