Is anyone else experiencing an extremely strong (40 over)  noise signal on 3.678khz and every 100 khz all the way up the band? Same thing on 40 meters.  I may as well forget about 40 and 80 if this keeps up.

sounds  like invasion of the body switchers er snatchers.  Shocked Huh  so many of them around now.  small shortwave rx may help you find them for proper disposal.   I had to go back to coax fed antennas here for that very reason.

 Not trying to hi jack the thread I think this may be relevant.  There is a huge internet cable running thru my neighborhood. It has all sorts of cans and gizmos on it. It will trash an AM car radio at evenly spaced intervals. It has harmonic all the way up past 40 meters. I can take pictures if any one is interested. If I lived next to it a AM radio would be useless as well as HF gear. I don't know how they can get away with this. I was thinking that I should log a complaint with the FCC.

My problem turned out to be a radio shack switching power supply.  I guess something inside it must be giving up the ghost.  I removed it from service and went to a transformer type supply.
