Filter Replacement and sharing experience

Hi all,

there appears to be moderate interest in doing the filter rework and I
encourage anyone that modified a phone to share the experience with all of us.
I have created a simple docbook that uses the pictures uploaded by Luka and
annotates them with a "calloutlist". The docbook xml can be found here[1] and
the draft PDF is in the wiki as well.

It would be nice if all of us could contribute about the motivation of the
rework, maybe a bit of history (how the RX path was identified, how new baluns
were selected, ...), experience/tools used during the rework, review the
draft, note the differences of the various phones.

cheers
	holger
