Well, the jamming has been S7 to S9 here in the Pacific NW. I have a rotatable dipole on 40 (SteppIR "trombone") and I can drop it an S unit by point an end to the SE. Not very directive. My waterfall matches those that have been posted except for signal strength. I agree that it is coming from Cuba where their govt and their people are in major disagreement. The Cuban govt dropped the Internet already and I think they ran out of things to do to block their citizens from each other and the outside world. So, they fired up their old jammer and pointed it to a section of 40M popular among Spanish speaking hams in the Caribbean. I noted that the jamming did not affect the FT-8 freqs nor the CW end. They're not targeting message flow because there isn't a message flow. However there may be some Cuban hams wanting to deliver health and welfare messages to stateside relatives. They can still do that on 40 CW - no jamming there that I can detect. Jamming a station vs a band of frequencies seems easier and probably was effective years ago when they jammed some Florida broadcast stations. This broadband jamming seems seems aimed at S Florida where the Cuban govt knows most of stateside relatives live. From my perch in the NW USA its just annoying. If I was a W4 in S FL I would be more than annoyed - "40 over 9"! One last observation. Watching the waterfall centered on 7135 or so, I noticed a QSO pip up freq, then watched it move down freq past 7135 then back up. Then a QSO popped up at 7140 and this moving pip coasted down and stopped on the QSO. Tuning in it was a W6 talking to a W2 station. The pip sitting on top of their QSO added a warbly sounding signal. Last night it was moving from 7110 to 7150 (or so) back and forth for quite a while. I'm wondering if that's a jamming signal that seeks an active transmitting station?
