I am building different Un:Uns using different wiring schemes and caps. While testing a config, I noticed that my battery was down to one bar and I did not have the USB cable plugged in at the time. I

Ken, looking through FCC part 15 rules on emissions, I don’t see any exemption for electric car motors or power systems. Do you have a reference to a FCC document for the exemption you mentioned?

Okay wait, I see what's going on here. The frequency graduations don't really match the labels. What I took to be a vertical line at what is labeled 146.2 MHz is really lower than that frequency,

Hi and thanks for getting back to me... I manually set the markers in VNA Saver to match the markers set on the VNA - double checked this a bunch of times. Marker settings everywhere match. See
