Many users of the nanoVNA have expressed interest in a version that can be used as spectrum analyzer. During the last weeks I have been designing, together with Hugen, of a self contained, ready

I have to agree - I have been pulling out my hair trying to tune a 70cm QFH (Dual 1/2 turn helix) antenna. The results I get is very sensitive to length, so much so that I gave up in the end. I have

Hello all, just a quick introduction from myself. Recently purchased nanovna H. Looking forward to getting to grips with it potential. Thanks to all those who have shared their technical knowledge, I

v0.1.4 2020-03-26 : This update requires recalibration of the device 1) Supports 0dBm output (fundamental frequency, for HW V3.1 & HW V2.3 only, for HW V2.2 still -13dBm output); 2) No new features

Not if any portion of the code is open source. If the code was entirely rewritten from scratch (doesn't seem likely), then it's OK.

Hello, NanoVNA-F has it's own groups.io and after-sale support~ You can visit groups wiki to get what you want: /g/nanovna-f/wiki/How-do-I-upgrade-the-firmware

Yes, I agree. Because it is an OSS project, we have not restricted BH5HNU to continue to sell NanoVNA-F. But do you think NanoVNA-F is still an OSS project? Developers can release binary files without

All, Where can I find the instructions on upgrading to the latest firmware version for the -F model and what is the latest version? Thanks in advance... Larry, K4MLA

Doug, I will try that tomorrow.... that’s one thing I didn’t check

Here is a second report on the effect of calibrating the NanoVNA on SWR and Return Loss measurements. This time a 20M dipole was used as the antenna. It was surprising to me to see how good the

Unless he signed a non compete contract while he was employed by you there is nothing that you can do. OSS project, anyone can sell their own copy/version.

I did some measurements today on a vertical whip antenna tuned for the top end of the 2M amateur band. I wanted to see the effect of calibrating the NanoVNA on SWR and Return Loss measurements? The

I'd say "Welcome to the world of open source. That's how it's supposed to work." The whole point of open source is that if someone thinks they can do better, they should have the chance to try. That

I have several CDE silver mica capacitors I ordered from Mouser, and have several more on back order. I bought leadless surface mount capacitors, but they also have leaded varieties. The ones I bought
