6999 kHz USB, 6998 kHz USB and 7000 kHz LSB are all active at once. Not to mention the amateur radio operators transmitting CQ on 7000.1 kHz and 7000.2 kHz, going by the signal strength, these ham operators are at least attempting to jam these intruders off of 40 meters. Unfortunately it doesn't seem to be working.
6999 kHz USB 6.999 MHz USB - YL and OM talking, can't really make out the language because there's so much QRM. 6998 USB is also active and there's some weak signals on 7000 kHz LSB on top of that. Naturally, the CW signals are owning the frequency, making it impossible for me to make anything out. The 6999 USB stations don't seem to mind though.

CW is such a pitifully inadequate way to jam.
Most modern SSB radios have auto-notch or notch.
But maybe it makes hams think they are marking their territory.

Indonesian "village radio" are always on 6.995, 7.000 and 7.045MHz LSB during my nights this way, they also break out into "chanting" sessions which is quite comical. They have been there for many years and no amount of amateur radio jamming has yet to move them... ;D

The Indonesian changers on 7000 kHz, 7045 kHz and other frequencies are world famous as far as intruders on 40 meters go. They’re right up there with Asian fishing fleets, Mexican truckers and Russian taxi cab dispatchers using frequencies in 10 meters, especially the lower part of 28 MHz. The vast majority of export radios used by these intruders go up to at least 28.305 MHz. Some of them go up to 28.755 MHz and the modern generation of Chinese export radios cover 25.615 MHz to 30.105 MHz instead of the old de facto standard 6 band 25.615 MHz to 28.305 MHz coverage. But who needs an export radio or 10 meter radio when you have a regular HF amateur radio and can simply use 40 meters?
CW is a pretty bad jamming mode. These hams were sending CQ over and over again, the one on 7000.1 kHz was doing it nonstop.
