Would any time-nuts know of radiolocation-type testing going on, on east
coast of US, maybe around Maine? There is a very strong wideband signal on
1900-1920kHz, with a 120Hz substructure and a 4Hz rep-rate, likely megawatt
power range.
Sound sample (recorded with 2400Hz receiver bandwidth, although the whole
signal is far far wider bandwidth) at
http://www.trailing-edge.com/1910-intruder.wav
Pics of the waveform at http://www.trailing-edge.com/1910-intruder-1.png and
zoomed in at http://www.trailing-edge.com/1910-intruder-2.png
Could it be an artifact of interference with NAA 1-1.8MW@24kHz
which also uses ~3MW@60Hz for deicing on the inactive array,
as it is now below freezing and fairly humid in coastal Maine

Take care. Thanks, Brian Inglis
