Ahhh, another source of noise located

Remember that stupid line in the lower third of the 30m QRSS spectrum? As said before, earlier tests have shown that is was due to the built-in sound card. For a change, I wired up my two diodes to the rear Mic jack, and guess what? No stupid line. My system has got two built-in sound cards one of which is O.K., and the other is c###.
