NanoVNA V2 user group / Official support forum

This is the official support forum/user group for the NanoVNA V2, which is a low cost 3GHz T/R VNA (vector network analyzer). It is not based on ttrftech's NanoVNA design but a new from scratch design using 2 ADF4350 to cover up to 3GHz and Si5351 to cover down to 50kHz. Compared to the original ttrftech design, V2 uses only the fundamental signal for measurements and achieves higher dynamic range.

There is only one official NanoVNA V2 forum, which is All other groups are unofficial and you will only get support on this forum. Check the official website for user groups and social media pages:
