I have not caught up to all the subsequent comments cross-posted or not to some or all of the lists --- but replying to this from Les:
By `maximum null of 330 degrees` I think he must mean off the broadside of the loop/ferrite, not off the ends, right? Otherwise as Tom et al. have explained the ``maximum null`` at 330 would really be the bearing of the station (or -180 = 150), (like 170 is for Tom) rather than 60/240 as Les says it is for him. He`s getting the least, not the most signal, at 330, whichever way you determine that by looping.
Tom calling 170 the ``null`` (minimum signal) as he has made clear, is really the maximum signal bearing, only made to be minimum by orienting the antenna`s null toward it.
It`s too easy to get this backwards. One can always get it straight by comparing with bearings of known stations.
BTW, my guesstimates are going by true north, not magnetic north. Another way we all need to be on the same page with this exercise.
73 and good night, Glenn

Glenn,
Sorry. A bit under the weather
the past few days.
But
Iâve checked and rechecked the reading from here. Maximum
null was recorded at 330 degrees. That puts the mystery
signal at a bearing of 240 degrees or 60 degrees. Rotating
the portable radio shows maximum signal from those bearings
as well.
73,

getting more and more confusing. Tom, do you mean then that
the maximum signal would be 90 degrees away from 170, i.e.,
80 / 260 degrees, or do you mean that 170 degrees is the
direxion of the maximum, not minimum signal? I thought you
previously found it to be southward from you.
