I had already planned on dragging an HP signal generator and precision
attenuators/pads home this evening to check that out. I will the tests and let
you know. Let me know what you measurements show.
I would think that daylight hours would be the time for any accurate signal
level measurements from WA and TAG. I dragged the crosshairs across about 20
minutes or so of WA and TAG code elements and the variation was less than a dB
or so. At night it would be all over the map I would imagine. NC was not nearly
as consistant as you guys.
