    Much wider... CODAR is 30 to 40 KHz wide, the old Woodpecker literately took out the ENTIRE ham band, that's 500 KHz. I suspect it was wider than that too... CODAR also runs in the hundreds of watts range, whicle the Woodpecker ran in the megawatts range, and had great antenna arrays to boot.

    Yup, been hearing it, but definitely not the same as the woodpecker. My noise blanker is fairly effective against this current PITA. Against the ol' woodpecker, the NB was totally useless (at least that was my experience in Europe during that era; CONUS may not have had it so bad).

    This is exactly how I would describe what I heard at about 28.470 most of the day yesterday.

    Does anyone know where this new OTHR is coming from? I get it on 40M quite often these days...

    I can hear a very weak, slightly pulsating carrier on 7040, using my 3-transistor RX. But not, as I understand it, a classic woodpecker.

    Remember the MOSCOW MUFFLER?

    Remember those VERY well. I owned two of them. They were largely
    ineffective but helped at least in my experience. I wish I had kept one
    of them just as a novelty in the shack.

    Anyone who experienced the original RWP will likely never forget how HORRID it was.

    The new one at least isn't ubiquitous - at least not here - as the original.

    Haven't heard any woodpeckers on the air, only a few cuckoos. :rolleyes:

    Perhaps N. Korean SNR-75 ‘Fan Song’ Fire Control Radar.

    Be glad of that. You think power line noise is a QSO killer? The Russian
    Woodpecker was a "turn off the radios and do something else" infuriating thing
    that would randomly destroy an otherwise fun and productive evening on the radios.
