Re: NanoVNA and PC.
OK, I understand but you still have not answered one question: Can you talk to your H4 through Terraterm or putty?

Please install this version of firmware for your H4: /g/nanovna-users/files/Dislord%27s%20Nanovna%20-H%20Firmware/NanoVNA%20v1.0.69%20fw%20pack.zip Unzip and ONLY use the _H4_ DFU file. Verify you can talk to the command console through a terminal program on your PC before trying to use any of the Nano PC apps.

you have not said what model of Nano you have. Are you able to talk to the Nano through a termial program like Teraterm or Putty when it is connected to the PC? If not, you need to troubleshoot that first. On Monday, December 13, 2021, 08:32:18 a.m. EST, Antonio (EA7HJ) via groups.io <ea7hj@...> wrote:
I have updated V1.1 the firmware, but I still can not use the software such as Nanovna, Nanovna-APP, Nanovna-Saver, Nanovna-Sharp and view the PC on-screen curves. Can someone connect to the PC with the aforementioned software?. The nanovna-app even update the firmware perfectly, however to see curves does not connect with the device. I have also tested with the Zadig driver and does not connect either. Any help about it? Thanks in advance. Antonio - EA7HJ |

Re: Nanovna H4 very slow sweep speed?
Sweep speed depend from bandwidth.
You can see this setting in middle of frequency range at bottom "bw: XXXXHz 101p" Lower XXXXHz value - more slow sweep time For select use DISPLAY->BANDWIDTH (default 1000Hz, more faster 4000Hz), this option stored in config, so after need save it in CONFIG->SAVE |

Nanovna H4 very slow sweep speed?
I just got a nanovna h4 off Amazon with good reviews (seller HUAIFANGPING)
It seems to sweep very slow (about 8 seconds a sweep). Every time I adjust the antenna, it takes about 8 seconds to see the trace refreshed and the SWR updated. Is this normal for the h4 or do I have a dud? Online videos show much much faster sweep speeds on other nanovnas... Thanks! |
Re: NanoVNA and PC.
Does this Hugen releasae include the enhancements DiSlord released earlier today as DiSlord v1.1 beta 1?

First of all,? thank you DiSLord for the responses, and I echo the many other comments in this forum about the most excellent support you continue to provide! I opened the case on my H4 VNA and found the silk screen outline for the card slot, but in my case the connector is not populated.? The good news is I have sufficient skills to solder one in.? The bad news is I don¡¯t know what part to order.. Gary, if you have a link, please post it?? -- Regards, Robb N2VJO |
