What Is That Wideband 4.5mhz - 5mhz signal??
« on: April 29, 2018, 0125 UTC »
I'm getting back into UTE dxing after being away for many years... So I'm tuning around the 4.5mhz - 5mhz area, hearing this wide band "zeewosh, zeewosh, zeewosh" at about one second intervals. Reminded me of the old OTH radar interference. What the crap is this crap??  :P :P

This is a radar, but not an OTHR really, although yes, it does see beyond the horizon.  This is a specialized coastal radar called CODAR.  CODAR monitors wave action and coastal ocean currents.  There are literally hundreds of CODAR installations around the world.

Thanks for the reply Token. Man, that sure makes a mess of a large section of spectrum.
I wonder how this could be legal with the ITU?
