Billy,

I suggest you learn to use what you presently have working before you start upgrading firmware and using different apps.

Some new users have problems (getting driver installed, understanding firmware update SW etc.) upgrading their NanoVNA. What you have now is probably all you will ever need and it works so just get comfortable with it and learn how to use all the features of your NanoVNA.

NanoVNA Saver will do most functions easily and many users just use this app and don't bother with others.

Many questions that you have can be found by reading the Absolute Beginners Guide v1.6

/g/nanovna-users/files/Absolute%20Beginner%20Guide%20to%20The%20NanoVNA/Absolute_Beginner_Guide_NanoVNA_v1_6.pdf

Here are some links on how to use NanoVNA Saver





I hope this helps. You should have enough reading material to get you on your way.

Roger
