I could not find any threads that answered this question so here goes. I have seen a lot of videos of calibration of Nanovna using the Saver program, some show calibration only in the program itself and others show calibration in the Nanovna prior to connection to computer and then in the program. My question is it necessary to have the Nanovna set to the frequency to be tested and calibrated before connecting to the computer and Saver software? I am primarily testing swr on homebrewed 2m and 70cm antennas for my own use. Thanks for any advice.
