I get various weak carriers from time to time in the band, which are 
not stable and drift. I have always assumed these are birdies coming 
out of my pc/router as is the somewhat stronger burble I get on 
500.00 which goes off when I turn the pc off. I suspect this is what 
you are hearing Alan. Adrian put out a reasonably stable signal when 
he is on, he doesn't beacon, rather more lots of CQs.
