You may be looking for the graphical version of the map, but I threw this into the AI Grok app on my iPhone and it listed them all out. “ Menu Structure Map for the NanoVNA F V2.” You may or may

There are a bunch of them online. Have you tried Googling? Compare the menu that you think is right to your NanoVNA because there are several variations. [email protected]> wrote:

Off subject, does anyone know where to get a Menu Structure Map for the NanoVNA F V2. My new one did not come with one. Thanks ________________________________ Sent: Thursday, March 13, 2025 1:54

Mitch, Try making the ground connection to your filter very short, say 5mm or so. Also, try multiple ground wires. The currents to ground from all the capacitors in the filter flow through that

Hi Jim, Thank you for your suggestions. I will shorten leads and properly dress the components tomorrow. BTW I had no 270 caps but had 50s and 220s, hence the two caps in parallel. You make a

Hi Jim, Correct. I failed to connect them. I've repaired it and get a slight improvement. See pic just posted. Many thanks. Best, Mitch NK3H

Alan, exactly right. I failed to do it. I just posted a pic of the result of adding leads from copper plane to the ground on the test rig. Thank you. 73, Mitch

Correct. I failed to connect the ground plane to the connector grounds. I did just that with hookup wire soldered to the copper and connected to the ground of the test rig. A slight improvement. See

Alan, I agree 100% on neatness, lead length, etc. This was supposed to be just a test project in anticipation of properly building the filter. From your comments and others', it appears I need to use

Dave, Thank you for your reply. Very much appreciated. In order: 1) Done. 2) Yes, I measured all components with my LCR meter (DE 5000). 3) Correct. 50 ohms confirmed by others for this

HI Dave, Yes, it's there. The line goes across the very top of the screen, and the print shows "S21 LOGMAG 10 dB/-0.00 dB" in gray. Thanks for any help. Best, Mitch NK3H

The only measurement noted at the top of the screen was S11. Was S21 also there? I didn't see

Well, there's a long history of dead bug construction, and 3D sculptures. But it's the short leads thing that's biting you here. You can solder the capacitor lead to the copperclad really close and

I don't see a connection of the ground to the copper clad. But more than that, the leads are pretty long. A rule of thumb is that 1 cm is 10 nH, so it looks like you've got 40-50 nH in series with

I see two yellow wires for input and output but NO ground lead from the copper board to each of the coax connectors

EXACTLY... As I was walking away from the screen shot and getting ready to pull the plug! Again... NEATNESS COUNTS in this process.

Here's a plot of the expected response from Elsie

One thing you could also try is running the filter in a program like Elsie (which is free, for Windows only, though) and look at the S11 plot from Elsie and see if it looks like what you're measuring

Mitch, It looks like the ground (copper plane) of your filter is not connected to the grounds (outer conductors) of the cables. That would make a big difference. --John Gord

Hi Mitch. Dave can assist and we have confirmed that you filter in indeed set up for a 50 ohm source and load termination. The response is validation from a simple AC simulation. I looked at your
