Re: My NanoVNA is not recognised by DFUse when using V 0.2.3 firmware
reports "you have the latest version"Zadig software simply ignores such misleading messages to install the >>correct<< driver, namely: right-click on DfuSeDemo icon, select "Open file location" * start in the Bin folder that has DfuSeDemo.exe * nanoVNA wants driver in that Driver folder You can right-click on the device, select "Update Driver Software" * "Browse my computer for driver software" * browse to the location above for your Windows version |
Re: NanoVNA-Saver 0.1.5
Hello Rune,
Unfortunately, quartz filters have a ripple. In the Attachment the plot of an IF quartz filter. One possibility might be to select rising and falling edges. Otherwise, I currently have no solution. Viele Gr????e Hans-Peter Prast, DL2KHP ========================================= Hans-Peter, yes, I appreciate the ripple issue. Perhaps one approach might be to scan for Fmax, Smax and then approach upwards from a low frequency until Smax - 3 dB is reached, and then approach downwards from a high frequency until Smax - 3 dB is reached. I've not programmed that, though, just a suggestion. 73, David GM8ARV -- SatSignal Software - Quality software for you Web: Email: david-taylor@... Twitter: @gm8arv |

Also I do not use the "jog" switch.
I drag and drop the markers / and use all menu's by the touch screen. I also use a simple and very cheap PDA stylus. It makes life very easy and simple. 73 de Andy |

I have boxed my NanoVNA in an aluminium box, no problems.
For the power switch, I simply connect a switch across the original switch, because you must keep the power connected to the charger controller / original power to work properly. For USB connection, I use magnetic USB connector. 73 de Andy ![]()

Re: NanoVNA vs. NanaVNA-Saver
#calibration
Hi, RUne,
I think that the full calibration of the device from Your software would be very useful for people (like me) that are using the nanoVna at 99% from the PC. If possible, please, add this feature ! - thanks in advance ! - Andrea IW2FDH |

With NanoVNA-Q firmware there is no needs to power off/on after USB connection. It allows to read paused sweep. Regarding to USB disconnection, the reset happens due to hardware issue. IP5303 just remove power for some short period of time. So, this doesn't depends on firmware. You can keep NanoVNA alive with no reset at USB disconnect by applying external 3.3V power on the SWD connector at the right side of NanoVNA board. May be adding some capacitor on power line will help to keep it alive with no reset. Needs to try. |

Thanks for comment on my question. Makes me feel better to not worry about overcharging.? 73, Bruce, VE1II On 11/11/2019 1:49 PM, Larry Rothman wrote:

Yes - you can leave it connected to your computer - the IP5303 chip will stop charging the battery automatically. Cheers, Larry - VE3LRI On Monday, November 11, 2019, 12:24:14 p.m. GMT-5, Bruce Harvey <bharvey@...> wrote:

" 1. hugen is of course the first person to mass market the NanoVNA and current manufacturer of the NanoVNA-H. 2. flyoob is the manufacturer of the NanoVNA-F. 3. bepissneks (parent of OwOComm), I'm guessing, is manufacturer of NanoVNA with the white salamander design as it is the most marketed clone outside of hugen's. 4. I originally thought Gabriel was a member of hugen's design team but her web presence indicates she is part of OwOComm. Can anyone confirm the above is correct for future reference? - Herb |

You're using Linear scale on NanoVNA display and Logmag scale on PC software. This is why there is difference. By the way, there is more functional software NanoVNA software for PC: it allows to capture screenshots and show more trace types. |
