Thanks, added to /g/nanovna-users/wiki#NanoVNA-H4

My 2.8" NanoVNA-H v3.4 arrived. I ordered it ($50usd) from hugen's Alibaba store on December 31st 2019 and it arrived January 17, 2020 via parcel post. As luck would have it, the 4" NanoVNA-H4 was

Ok, Erik! Thank you very much! 73!

I was afraid shorting R13 would overdrive CH1 as I did not have the resistors to change the CH1 input (R29-R31) Current CH1 headroom is less than 10dB -- NanoVNA Wiki:

Same as the original nanovna. hugen

I see it. But Erik wrote only about R9, R29, R30, R31 for improving CH0. Maybe he left R13 150 ohm? :-) That's why I asked him.

How fast full sweep and how many sweep points on this variants?

NanoVNA-H rev3.4 is fully compatible with previous versions of NanoVNA firmware. The NanoVNA-H4 uses a Cortex-M4 MCU and a 4-inch LCD, so it is no longer compatible with previous firmware versions.

Hello all, I'm at a loss. I was able to update firmware by going into DFU mode on my nanoVNA, but now that is not working at all since firmware version 0.5.4. The DfuSe Demo (v3.0.6) is not

David, Thank you.? I accidentally posted to the wrong list.? Sorry for the extra bandwidth. Ray -- They say a smart person learns from their mistakes. A wise person learns from the mistakes of

Roger, Have a look at Erik's post from earlier today. Those are the changes that are documented in the latest schematics for hugen's design v3.4 I hope you have a microscope and a steady hand in order

The D2 story is: few nanoVNA were shipped with any D2 installed. 1N4148 was installed by some, Schottky by others. Just as most nanoVNA (except gecko) have type C USB connectors while few have the

Hi Robert - This comment in your first message is a concern: Ubuntu 18.04.3 LTS surely has a tmp folder for updates... Linux distros generally have packaging schemes which typically do not use pip. To

I did check and saw this comment by Hugen... "Please note: Starting with NanoVNA-H rev3.4 D2 uses IN4148, if your NanoVNA D2 is a Schottky diode, use the "vbat_offset 150" command to calibrate the

Rudi: I'll look into PyQt5 not installing issue. Rather be working on this than blowing snow in my driveway...... I've been running Ubuntu for years, and still I'm a novice. Thanks for taking time for

Hello Robert, Too bad. It helped me, therefore I told you. What is strange for me, PyQt5 was downloaded OK, but was not installed. 73, Rudi DL5FA

I was thinking ahead and picked up an USB extender. Didn't work. This summer I'm hoping to put up a modified .64 wavelength antenna (formerly on 11m). Measuring the Z of the antenna then designing the

You have to schort R13 and change? R22 upto included R24 also : R22 and R23= 51 Ohms , R24 91 Ohms, R25 = 11 Ohms. After this you have updated version 3.3 to version 3.4 as far as possible (without
