They are just included as extra parts for you to use for your projects or to build a calibration load using the spare pin sockets. Roger

The Gypsy antenna looks quite loosy with only two real resonances. Those being roughly 9 and 16.5 MHz. It hugs the outside of the Smith Chart which indicates loss. Not a very good antenna in general.

Hi All, I am a new owner of the nano vna and i am not really sure how to read the results of the plots. Originally i had just strung up a random wire between my garage and back fence and i have since

Hi, I bought mine through Amazon. It cost me a little more but there is assurance that you won't get ripped off. I bought my first tinySA through them too. My second SA I bought used from another ham

Amazon has them, and if you want you can easily return them AC6K [email protected]> wrote:

I have a NanoVNA which I love but now it's time to upgrade to a Nano VNA-H. Can someone please recommend a trustworthy site Thanks... Vin

Hi all, I assembled the whole circuit. I have a doubt about the calibration resistors: they must be soldered on the pcb or on female pin? Thanks and 73's

Alan I think that the shipping would be prohibitive, especially to you guys in VK land. Here in the US many libraries have 3D printers for use for the cost of the filament. There may also be a "maker

Hello Bob - For us that don't have a 3d printer or access to one do you propose to make and sell a complete assembly ready to use. 73 Alan VK7AM/GM3MHD.

I appreciate all the great responses to my question that I received . My problem was that I could not apply enough finger or thumb pressure to make the connection. It was painful to try. I used a

I'm not so sure.. in a VNA, the return loss bridge can be pretty crummy, because any leakage into the reflected path or lumps and bumps in the forward path gets "calibrated out". Similarly, you don't

Sorry for the 64-bit version only, I will publish a 32-bit version as soon as I have configured my development platform! 73s de Karl Jan - LA3FY

Calibration routines for a VNA are not as difficult as you may think, just a few lines of code. If you use a programming language that supports complex number division, it is very easy. If not, you'll

Hi Bob, Unfortunately, eBay may give you a misleading title to sell a product. (it may be the case elsewhere, but I’ve experienced it here). This product, which you mistakenly write nanoVNC-h, is
