Q: Where can i get the adaptor for the nanoVNA so i can fit the pl259 to it ?.

Just look up ‘sma to pl259’ in Amazon search and they are there as either plug adapters or as short cable connectors

Q: Has anyone had difficulty with using the touch screen menu? I cant get the dang thing to calibrate becouse it will not goto any selection.

I have had no issue with mine. You may already be aware of this, there is an American radio ham who really understands these units and has many posts on YouTube explaining how to utilise and set them up. You could try there.
