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?

Absolutely no ICM products heard,
