Just need someone to knock up an STL file so we can 3d print it ;) Any takers?

That can be a problem with a decentralized project. Mel, do you want to meet on 80 meters later? I¡¯m at my wife¡¯s place in Nevada City, so I¡¯d think propagation along the foothills ought to be

Nicely done Ken. I too am concerned about junk getting into the open areas. Thanks Mel, K6KBE

Hi all, The link below is for the chassis I made for my NanoVNA device I recently received. I was concerned about damage to the rocker switch and the power slide switch. I have also included a little

OK, but not knowing what that is, did anyone rewrite the manual in English? The words are all english but don't make a whole lot of sense. Reminds me of the days when the off shore boys wrote the

I am *not* a metrologist, but I find this document useful ¡°A Beginner¡¯s Guide to Uncertainty of Measurement¡±. It is written by a lady at the National Physical Laboratory (NPL) in the UK.

I see it called edy255 and also edy555 so I didn't know which number to post. https://github.com/ttrftech/NanoVNA/releases/tag/0.2.3

Thank you. You are doing great work.

You're right, there seems to be an old 0.0.10 in the files area. I have reported it to the admins to have it removed. The old versions are available on GitHub, but there's no reason they should be

Hi sala nimi, The latest version is 0.1.2 which you can get at https://github.com/mihtjel/nanovna-saver/releases/ -- Bryan, WA5VAH

I think I just installed the version 0.12 while there is version 0.10 in files. Version numbers with a lot of .... are a bit misleading, so I am not 100% sure.

Preferably, with a 50 ohm load on both ports. If you only have one, put it on "ch1" (port 2 - confusing numbering). Isolation tries to establish and cancel out the base level of noise in the passive

For your info. There are calibration kits in Ebay where the center pin does not rotate while attaching the connector. Price was about 13€?$

I am using NanoVna saver software and the last action in the calibration dialog is "isolation". How do I do it or how it differs from "open" calibration? Regards LM

...and attached is the missing screenshot...

Thanks very much, Cecil. I've been too chicken to attempt updating the firmware. Maybe it's time to bite the bullet. Mel -- edy 0.2.3 is *firmware* that would need to be downloaded onto the NanoVNA

Please be aware both code space and ram are almost full. Any big additional functionality will imply taking out other functionality possibly leading to PC side incompatibility. Do not dig a private
