The odd thing is that the COMSpkr appears to be the same device as many
of the generic computer speakers *except* the bypass/RFI suppression
parts included on the chip makers reference design are present in the
West Mountain Radio product but are lacking in the commodity products.
I have "cleaned up" several of the generic ($20) speakers by adding the
necessary parts to the holes *already present* on the circuit board!
