Watt,  Thanks very much for your observations.  Many of us hear in North
America are also hearing the noise.  It is certainly having a negative
effect on world wide communications. At the very least,  I believe that we
should all make our concerns known to our respective governments in the
hopes that they might actually add it to their list of "things to do".
Clearly noise such as this is a violation of international agreements and
spectrum allocations.
    I might also suggest that we all beam the biggest signals we can in the
direction of the noise and spend a lot of time on the air, even if only
local contacts are possible.  While this may be a futile exercise, there's
just a slight chance that we might be able to QRM the intruder; and we
should not concede the bands by default.  Thanks for your valuable
information.  Bob  N7UA
