morse code from baby monitor
 

I wonder if anyone can throw light on this. I have a Tomy radio-linked
baby alarm. I find that when the receiver is plugged into the mains
unit I get faint morse code coming from the receiver. Interstingly it
seems to be RF pickup from the charger leads - it 'works' even if the
charger is not plugged into the mains.

The morse is being sent at about 40 characters per minute. There are
long strings of letters followed by pauses. But it doesn't seem to
make any sense. here's a typical sample:

ieideaeigeeetiesetneelneetsertedeteeit

I also get the odd isolated digit from time to time in the middle of
the letters.

Any thoughts?
