Probing or troubleshooting a keyboard or other digital electronic instrument with a portable AM radio


At your risk.


It has just been tried on 2 Yamaha PSS-480, (one of them only operating).


While approaching AM small radio to various places of non working unit, noise is polite.


On the working unit demodulate noise is much less polite or many orders of magnitude louder.
