Also check the squelch button on the Becker radio. It is easy for it to be
pressed accidentally and the squelch to be switched off without you
realising it. A quick check is to switch the radio off and see if the noise
stops. Of course if it has been there since build it could be an
installation problem, most likely in the intercom wiring.

Turn the Squelch knob to the left on the 403 MC. It is picking up the
ambient noise so needs to be less sensitive. I had similar sounds and this
cured it. Just turn it until the unwanted noise stops, too much and you
can't hear your passenger.

anyone any suggestions what could be causing this or have you had a similar
problem that you resolved, Suggestions would be welcome?
