So yes...quite possible to accurately sense where a signal is coming from. The argument FE'ers would take might well complain about compass bearings and such like. But in theory you could compare the bearings against each other, perhaps include a control...and bob's your uncle, that's one very very solid argument. Nice one Smiley

The compass bearings, or absolute directions, don't really matter - you just measure two angles and subtract them to calculate the angle at your corner of the triangle.

edit: Just while I am thinking about it, how much bearing deviation would you expect over a round earth 3 Tesla? anything less than 5 would be acceptable error for field strength meters. I can't say how accurate the bellini tosi systems are as I've never actually used one. I'll ask my father - he has many a time.

Good question - I'd have to work out what theb theoretical result would be for a real triangle over a round earth and see how much more than 180 degrees the angle sum would be.

**And here is my dumb-ass modification:**Good question - I'd have to work out what theb theoretical result would be for a real triangle over a round earth and see how much more than 180 degrees the angle sum would be.

I haven't forgotten about this - I'm still looking for a globe (of The Earth) so that I can measure some approximate angles ...
