Hello good morning. checking the cavity adjustment video, it strikes me that within the adjustment process, the screws that hold the female connector to the cavity are tightened or loosened, my question is: those should not be touched within the readjustment process of the cavities due to changes in frequency?, or if they should be adjusted to achieve an optimal fit?

Does it matter what side u tune for return loss on. Seems I can always get one side great but not the other, going back and forth...

Dear Friend.. congratulations for you video... please you can make a video but in spanish... or with subtitules in spanish!! Regards from Chile!
