>From FN57RF at the 'tip-of-Maine' (N 47.2380 - W 68.7165) WGS-84, the bearing (True) is
220° ± 10° as read on an LF shielded loop of known accuracy/calibration. It is
predominantly a sky wave signal and getting a good null on it is not possible with a loop @
this QTH, so the bearing noted should be taken with the appropiate caveats!
It is a steady carrier with no modulation as observed on a spectrum analyzer connected
directly to the Beverage, and '.wav' recordings would not be useful. It was not detected here
during daylight hours today; it became detectable around 1545 - 2000Z, but still in the
noise. Someone within gnd wave range "down east" and with a good DF loop may be able
to contribute better bearing info. Currently it is S9 and building with very rapid QSB on my
240° Beverage @ 2325Z.
I believe it might be advisable to involve the FCC's assistance in DFing this one ... their MD
facility may be better equiped to locate this source during daylight hours.
