Mike,

Thanks for your reply.
It's CODAR. Radar applications used to measure coastal currents. See the
following URL:

In a previous thread, the CODAR speculation was discussed, but due to the
extremely powerful signals, heard across the U.S., it was felt that this
was a less than well-disclosed emission. CODAR is according to various
sites describing existing systems, low power. Quoting from the site you
referenced above:

" Each remote site contains two antennas and a small 6'x 8' shed.
One antenna (left) transmits a radio wave out across the ocean surface.
The power of this transmitted signal is only 40 watts."

Any amateur doing QRP would envy the punch of this signal at only 40w if
this is truly the source ;-)

I've had the initial researchers who developed CODAR confirm this signal
years ago. They could not believe the propagation as I was over 1000miles
from the test site. Unfortunately, now that it's in full commercial
deployment, there seems to be hundreds of sites on several bands. Highest
I've heard has been 19Mhz.

I've tried to file a complaint with the FCC but unfortunately there are
no legal avenues as it has been approved by the FCC. Perhaps the ITU can
take complaints as this signal seems to block international broadcast?

It would not be so bad if these things would ID at the top of the hour so
at least propagation could be tracked.

I don't understand how they get away with broadcasting in the SWBC
bands. Someone on the west coast has been ruining the top of the 25
meter band and the low end of the 22 meter band for years now. I guess
it's time to start complaining.
