Hello Team, Did anyone sucessfully inserted the nanovna inside a metal enclosure? Will that improve any accuracy and/or stability? How to overcome the need to turn off/on every time we plug the USB

Re: 1500Mhz, usable ?
As Rune mentioned above, 1500 MHz is not the main goal for newer firmware. The main goal is to fix errors, bugs, make more stable and more precise measurements, add new features (such as TDR and Group

Re: Wait for NanoVNA-V2.....
I would pay a double price to have bigger screen, appropriate internal storage, and wireless capabilities. Maybe somebody can set up a vote :-) 73 Ady =========================== I've already paid

Re: 1500Mhz, usable ?
To put some facts in this discussion I measured the S11 of a a 25 ohm resistor from 0.5MHz to 1500MHz. The nanoVNA was connected via USB to a PC but running from a clean 5 Volt supply and TX power is

Re: 1500Mhz, usable ?
There are many versions of nanoVNA on the market. My black nanoVNA is fine up to 900 MHz. At frequencies above 1 GHz the track is dirty, uneven, unusable compared to other instruments. Lucio, I0LYL

Just curious...what IS the approximate transmit level of the Nano VNA? Thanks, K7UV 73

Re: Any plans to publish the NanoVNA board files
They are the same, the difference between V3.1 and V3.0 only increases C38, V3.3 increases R41, R42. hugen

Re: Any plans to publish the NanoVNA board files
Re: open source. V2 design files *will* be open source, both schematics and layout designs (gEDA PCB), and a few simulation files as well (RFSim99 & LTSpice & PLL simulations). The firmware is already

Re: Duplexfilter tuning question
Roland, I think the computer is set for logarithmic scaling, but the NanoVNA display is set for linear scaling. Values near zero cause deep downward spikes on a logarithmic display. --John Gord

Re: Any plans to publish the NanoVNA board files
Hi hugen, could you please share schematic for PCB rev V3.1. This is my NanoVNA PCB, but I don't have schematic for it. The only schematic that I found is V3.0 (thanks to Larry Rothman). I know, the

Re: My NanoVNA is not recognised by DFUse when using V 0.2.3 firmware
Next time to reboot PC. If it doesn't helps and you don't hear USB connected device "ding" sound when you connect USB cable in DFU mode, then go to Control Panel => Device Manager, click on computer

Re: Any plans to publish the NanoVNA board files
I have learned that three clone manufacturers have copied four different NanoVNAs, they are reverse engineering of my earlier versions and claim that they are doing improvements, but they don't know

Re: Wait for NanoVNA-V2.....
I read that nanoVNA-V2 feels stuck in a price box, so they won't be upgrading the display size. I don't get that at all. Why not offer various versions, e.g. V2a, V2b, V2c with different display
