I thought it was the pot too, but not if it happens with it off.

I have a military "Trangia" made by Svea that, if I remember right, has the inner wall and top all pressed from one piece of brass and the bottom another separate piece with the two pieces rolled together at the seam in the middle. It looks like the knockoff in the video is three pieces with the inner wall as a separate piece rolled into a cylinder.

I think Oops is right. If the inner wall of the knockoff is separate from the other parts of the stove, it may be expanding/contracting at a different rate than the rest of the stove causing creaking and vibration. If this is the case, maybe soldering or crimping the inner wall top to the rim of the stove will help? Need a bigger gap on the bottom of the inner wall?

Funny that I haven't ever heard this on soda can stoves built that way though. Is it possible the inner wall is a different material than the rest of the stove? Does a magnet stick to it or the stove body?

all seems to be same material but you all are right about a seperate piece for the center wall it is flimsy and probably acting like a reed playin a tune. also not magnetic anywhere

Maybe secondary combustion
