Noise from Io and Jupiter have a similar characteristic - could it be that?

Does anyone else have burst-like noise
appearing as "waves" every 5 to 8 secs?
I hear them practically every EVENING,
can listen only until abt 23-24 UTC..
Any other Finns on this reflector?

Example of noise level situation in the
MORNING, (12 May 2000, start 0250 UTC).
No "noise waves" during morning hours..
