[Elecraft] Noise in the Mideast

[Vic Rosenthal K2VCO]

Since getting on the air from Israel I notice an interesting noise on 
the bands 7 and 10 mHz and to a lesser extent on 14 mHz. It is a 
wideband 'schmutz' (technical term) which can take from 10 to 50 or 100 
kHz. Its amplitude drops of gradually as you move away from the center. 
It reaches S9 levels sometimes on 7 mHz.

It does not look like the typical switching supply noise. I do not hear 
it on 3.5 or 1.8 mHz.

The K3's DSP noise blanker seems to help a little, but not much.
Does anyone know what it is? Could it be some kind of spread spectrum 
transmission? It could be coming from anywhere in Europe or the Mideast.
