    Does anyone here have the straight info on the source of the S-9+ radar-type signal we are hearing most mornings in the Pac. NW on 80 and 40 meters? It sounds like a gas engine running. I haven't seen anything from ARRL on it. It's a different sound from the old Russian woodpecker.

    I have heard complaints from a station in Hawaii, about Chineese Over-the-horizon radar on HF bands..I was trying to work him on 60M CW and the radar let up long enough to make the QSO.

    I don't hear it 180 mi North of you in Everett, WA. Bands are quiet. 80m ant = cage inverted vee at 70', 40m ants = dipole at 65', 2 el yagi at 72'.

    That is an X-band radar, a little itty bit high in freq. for HF interference?

    I got some input from another forum. The general consensus is that it's coming from China. It was 20 over 9 here on 3825 this morning. Sometimes it's on 80m., and not on 40, and other times vice versa.

    The most common offender is a Chinese OTH radar. The Australians also have an OTH radar which can be heard on the HF bands, but they have not trespassed on the ham bands for several years.

    I thought all the 'Texas Towers' have been decommissioned as well....

    My 80 & 40m antennas are good enough to hear & work Asia, and I've never heared any of the noise you mention on 3825, or any other 80/40m frequency. How many and where are the other stations that are hearing it?

    They were. Fifty years ago. This is a floating, mobile rig that was built for development of the ballistic missile shield system and is now operational.
