Das Keyboard with ferrite core to reduce interference In disassembling a very old original Apple external CD player I came across a big ferrite core. I thought this would help solve the problem with 2 meter band interference from the Das Keyboard. And indeed, there is a lot less interference on the 2 meter amateur band. I tested with the Wouxun KG-UVD1P radio tuned to 145.500 MHz and I had to put the antenna of the radio real close to the keyboard to hear interference with the squelch set at 5.

Update: I notified the makers of Das Keyboard of this problem and my solution. The reply was a bit non-committal they will forward the suggestion to development.
