Tony, a long shot butI did a search on 0.533 second pulses and 
found a reference to motion detectors with 0.533 second dwell time.  
Did someone get a new motion detector for Christmas ?

 All,
 
 I have an RFI problem that I'm trying to identify. It's a 
continuous 
 pulse noise that pops on every 1/2 second. The timing between each 
pulse 
 is perfect (about 0.533 seconds) and doesn't seem to change.
 
 The noise is spread accross all HF bands and on some days it seems 
to 
 creep up into the 100MHz range; it's also stronger on the lower 
 frequencies. The signal is directional and goes from almost nothing 
to 
 S-8 with the antennas pointed south.
 
 The noise appeard suddenly in December and has not stopped. I have 
a 
 recording and would appreciate any suggestions.
 
 Thanks,

If this turns out to be the motion detector, or anything that you
identify, please send me a screenshot or the sound file so I can put
it up on our radio interference Yahoo forum.  Check out QRZ.COM to get
my email address.

Thank you!
