before adjusting coils do we calibrate the nanovna
Posted: 22 Jun 2022, 01:15
I am about to use my brand new nano vna to check the filters on my tr usdx. I see on various videos that the nano vna is calibrated with open/short/load before using it for SWR checks of antennas.
I have watched DL2MAN's video 20 times about tuning/checking the filters but he doesn't mention anything about calibration. I am guessing he suspects most know how to use the vna but I never saw one until today.
Can someone briefly explain if I need special calibration before checking the filters? And if so, which calibration steps are required.
Thanks you.
(I have sooo much to learn)
