RE: Re: [OT] Baby monitor picking up "hum"

Sounds like the filter capacitor in the PSU has dried up causing excess
ripple.

Try connecting a 1000uF capacitor across the power input to see if the
hum
is reduced.

I tried mine on batteries only over the weekend and the hum all but
disappears if the xmitter is battery only.
this suggests some noise on the mains.

Is there some sort of filter I can buy that will stop this?
