[RFI] Strange RFI

[David Cole]

Hi Dave, KW4DH),

This is normal and expected...  RFI can creep into many things, via many
paths, power, and output cables, etc., and not affect audio output in
any way, while still toasting the digital portion of things only, within
the CD unit.  

Add the ferrites, as described, (with as many turns as possible), and
the problem will most likely go away...  You don't have to hear the
RFI...
