Good morning:
I have recorded a problem like this with an 8566B in peak mode.  There is a 
continuous sweep from about 7.1mc to 8.5mc at a two to five second rate. 
Traced it to a neighbor who just installed the X10 security and home control 
system.  It's using the spread spectrum protocol and under 100mw but at 300 
feet, makes 40 meters unusable.  Appears that the FCC has lost control to 
dollars.  If you would like a Spectrum analyzer photo of the problem let me 
know.  Kindest regards Jim K9AXN
