However, I have already seem similar behaviour with an ethernet Cat5 cable and an IR receiver. While transferring data over the ethernet cable laying next to the IR receiver, the receiver's LED was flashing. I wass searching about 15 minutes for a remote control someone must be sitting on
Thats strange. The shielding of the Ethernet Cable is very good and should work both ways...

The diagnostics may be difficult. The comparison with the FM - Trasmitter doesnt really work since we have to take Frequency in to account. The problems with speakers is also due to the Frequency, as far as i know.

Without any resonance the signal would be much to weak to interfer with the Keyboard (or Speakers) i think.

Is the Keyboard connected via PS2 or USB? Cause then some HW-Geek could find out the Frequency this Standarts work with and than we could do some simple math to check if the Frequency of the Mobile is a direct multiple. Are other Keyboard functions influenced?
