Those on 20m hopefully will hear clear & frequent enough IDs to
not confuse stations involved with Chinese-speaking intruders
that are reported on our bands.

Much of the outside world is unlikely to hear many of the stations
involved on 40m due to interference from China's over-the-horizon
radar from Hainan.

It is unfortunate that across ITU Region 3 the best-suited amateur
service bands for regional emergency communications have for
years been lost to China's radiolocation service intrusions.  Hopefully
the 'Hainan woodpecker' does not cause as much trouble on 40m for
those involved as it does for us further south.

This despite an investigation by the government ombudsman in
Hong Kong that concurs with our telecommunications authority
that these radiolocation service intruders do _not_ cause harmful
interference to the amateur service here.

HRSA wishes CRSA the best of luck with its efforts to deal with
this unfortunate disaster under such unacceptable conditions.
