Hello,
Just got my NanoVNA H4, have upgraded the firmware to DiSlord's v1.0.69 and using the NanoVNA App v1.1.208 by OneOfEleven. Reason for doing so was to be able to get more than 101p.
After going thru the calibration, my S11 line starts out up and down (technical term), then goes to a flat line. Is that normal? Shouldn't it be flat all the way across? Attached is a screen shot to help what I'm trying to say, make better sense.
Thanks!!
