Topband: Unknown Pulse Signal Wiping out 1900-1925 kHz

[Donald Chester]

 Kind of a pulsating buzzing sound, centred around 1915, but audible down to
 slightly below 1900 and up to approximately 1925. At its centre  frequency last night (Saturday), it was just as strong as any CW contest signal.

It was particularly loud (S9 + 30) in the Northeast and ops with 
beverage antennas are reporting that it appears to be coming over the horizon
 in a south easterly direction, while others say it is possibly coming from Europe or 
Polar Russia. Whether this is a harmonic, a spur or something coming from an intentional radiator, it has made regular QSO operation between 1900 and 1930 almost unbearable for the past three nights now.  

All the more reason to hope that the FCC goes ahead and adopts their 
proposed reallocation of 1900-2000 to delete sharing  with radiolocation and to restore amateurs to primary status. Although many 160m 
ops seemed to blow off this NPRM while the comment period was still open as if it were much ado about nothing, a  few of us maintained that it was of utmost 
importance for the amateur community to flood the Commission with comments supporting their 
proposal. 

Although GPS has pretty much killed 160m radiolocation for the
 moment, we never know when some new service might attempt to start up in this part of the spectrum under the guise of Radiolocation.  That could be what's happening right now. For those only interested in DX and contesting in the bottom end of the band and who sometimes appear not to even consider 1900-2000 as part of the band, still must remember that if some new service were to displace amateurs 
from the top half, congestion in the 1800-1900 kHz segment (including the DX window) would likely become unbearable.

The FCC proposal, if adopted, would protect 
amateur status in the entire 160m band once and for all, and let's hope it is not already too late.
