and yes, if you do not want to do your own calibration you can use the internal

Hi Herb -
Thanks for reviewing

I would also suggest you are too close to the antenna you are trying to

Re: Questions about Firmware
A couple of questions.
How can I tell which version of firmware I have?
My NanoVna works fine as far as I can see.
