Suddenly background noise bip-bip

Help.Help.
Why have I suddenly been hearing a small regular beep-beep as background noise for two days now? It gets on my nerves! If you play you don't hear it but in silence...
As soon as I turn it on it starts quickly and then always slows down very quickly to one beep per second. It looks like a hospital machine that reads your heartbeat. What is it?
Thank you.

Do you live near a military base or airport? High powered radars will do such things. Also high powered tv stations or radio stations. Even a near enough short wave transmitter can create noise like that. Your keyboard is shielded to a point from RF (radio frequencies) but not all and not if they are very powerful.

Just something to think about. I have both keyboards (4x & 5x) and I am not experiencing your problem.

I am experiencing a high frequency whine from my Spacestation XL keyboard amp's power supply. Also a large amount of hiss. Aspine didn't use very quiet opamps or design a very good power supply. If he was still alive I would talk to him about it.
