Hi All,
I am seeing a strange signal centered on
474.750 kHz. It is periodically visible & audible on my grabber system
& my JRC NRD-345. there appears to be no data, just continuous tones. Both
systems using separate antennas.
I have placed a capture on Dropbox of the grabber
image & you can see the end of a previous period & the start of a new
one. The signal pattern starts with a bulge at the beginning but just shuts off
at the end.
I have also placed a capture from the JRC Rx with
SpecLab running at QRS01.
Any ideas or knowledge of this signal
?
