Sorry, the confusion was mine as far as the terminology. Right, of course.
Getting a null on a bi-direxional antenna means it`s pointing at (and exactly
away from) the station, i.e. the axis from which its maximum signal is coming.

WOW GUYS!
Basic NULLING 101!
If a station is east of you, it’s at 90 degrees relative.
OK Should be easy!
If you aim the end of a ferrite loop antenna pointing at
90 degrees (east/west) you are NULLING that station.
It’s
still at 90 degrees relative, it did not move, it is
stationary! GOT IT!
Now, if you rotate your antenna 90 degrees you get a peak
in signal, but your station is still at 90 degrees
relative, east of you. It did not move anywhere.
It is
still at 90 degrees relative! You don’t add 90 more
degrees to make it 180. It is still at 90 degrees relative
to the east!
My null on the 1500khz mystery station is at 170 degrees
relative (ends of Quantum Loop pointing almost N/S).
If I
go for a maximum signal by rotating my antenna 90 degrees
for a peak signal, the station is still at 170 degrees
relative! You don’t add 90 more degrees! The
1500khz
station did not move 90 degrees! It’s still to the
south
someplace at 170 degrees relative!
