    The crap seems to be all upband. Down below 7025, on CW, I just worked @LZ1EV, @OV1CDX, and @F5IN.

    The thread is probably useful to some degree... Today I was working FT8 on 17 meters. The band was open to the Caribbean and a couple of Cuban stations were on. Suddenly, I heard what sounded like a raspy buzzing signal and there were signals all across the waterfall that looked very similar to those shown in this thread and the other one. (thread that is...)

    The Cubans seemed not to be affected and neither were al the others working the waterhole this afternoon. Point being, that if that was jamming, it was ineffective at least on 17 today. and it was not there for very long.

    Just another data point for consideration.

    I think I was victim to this Saturday July 17th. I was doing a POTA activation on 7.230 in Eastern North Carolina. Started transmitting around 22:23 UTC and appox @ 22:45 ,I got a loud QRM signal. Lasted about 1 minute then was gone.

    Maybe yes mostly no. Lot of things that allow fast bursts such as you experienced. AC frequency drives on high horsepower motors are notorious for that type of interference along with other industrial operations. Jamming is usually a long lasting effect.

    THE "interference " seems to be in MULTIPLES---- around 7 130 7 168 LOWER AND ABOVE ---but there are still plenty of USEABLE space on 40 for qso's.....

    Maybe I got it wrong or maybe Im a relatively new ham and just don’t understand older hams mindset. But these are our bands. Yes we’re secondary users but we have privilege to use them. When the fcc gives away a portion of the band, everyone is up in arms. And when a decent portion of one the most popular ham bands is jammed by an entity that is jamming the frequency in order to halt beneficial communications to its people, no one cares and is willing to spin the vfo to “useable” portions without complaint. Including the ARRL. If no one is willing to complain about it, who’s to say the FCC will one day go after those portions of the band that ham radio operators just let go passively.

    1. What we do as individuals on air has no bearing or restriction on the ARRL, FCC or Dept. of State do.
    2. Work through the interference if you wish.
    3. On the other, hand, if you enjoy having a jack hammer in your ear, when other frequencies are clear; Go for it!

    As a former military comm operator, we trained to work through jamming because of necessity to accomplish the mission, and due to peace time comm plan limitations. As amateurs, we don't have the same limitations.

    My money is on Cuba. Josh from Ham Radio Crash Course (YouTube) has a short video on using digital software to triangulate where the signals were coming from. You guessed it, Cuba. Or maybe aliens living in Cuba...

    40m is a primary allocation for amateurs, not secondary.

    And I care very deeply about the situation, and the jamming. But the most effective way to show that we care, and to protect any of our allocations, is to use them despite any interference.
