[RFI] 85 pulse per sec. RFI once again.

[Colman Ahern]

My pet source of RFI has vanished for now, no doubt it will show up 
again. I found the below sound file on the RFI noise website, it 
sounds very similar to what I hear except for the repeat rate, the 
file noise is 60 pulses per sec., mine is 85 pulses per sec.

I live in Berkeley, very close to SF bay, is it possible that what I 
hear is a form of CODAR radar?  My source of RFI can be heard on many 
frequencies between approx. 1mHz-30mHz.  When present there is no 
change or fading in the signal level of RFI, however its level does 
vary depending on which frequency I am listening on.  A Google search 
did give some information on CODAR, "commonly used for mapping the 
ocean's surface and currents." (quoted from the RFI website).
