(there's aboslutely no need to get on the 50 ohm mark precisely, but that's another discussion)
Thanks for highlighting this, it is good to know I do not need to be super precise with this - I have kind of got distracted from making my current radio to seeing if I could actually get a really good match from 50 to 3k ohm even if I do not really need to. Before I got my NanoVNA I just used to guess and try until I got a good result but now I can actually measure these things it is really interesting to experiment.
I think learning about doing this and trying in practise will prove quite useful which is why I have been spending lots of time experimenting.
All the feedback I have been getting has been extremely helpful, so once again thank you, I really appreciate it.
