hmmm if you are talking about the clock noise intruding the signal
at long delay times, then this is normal. you have to use a
lowpass filter at the bbd-output to remove the clock noise.
if you are not sure that the noise is comming from the clock,
then maybe you can record a short mp3 or so and upload it to the
group, so we can take a listen?
