That the idiots that do not use ultrashort traces for the decoupling caps may have problems has nothing to do with this. You took the words right out of my signal/noise ratio.... For some peculiar reason older computers make less radio noise than the new ones. Especially my laptop's PSU which has a carrier at 120MhZ is way too powerful to be legal... I have wrapped it into copper foil and both cords have a ferrite bead over them. That helped the first 70 dB downhill. Still I can hear it at least from 500 meters distance. Maybe it is broke or it is contaminated by some new PSU virus.... |
