MP853 is a metal grounding earth spring that was added to the DDS board in 2006.? The picture you attached shows that the spring finger that is about 0.75" long had been broken off.? ?If you look in this group's Files section for?
/g/ic7000/files/7K%20GROUNDING%20FINGERS%20.doc?there is a picture of what it should look like.
I could not find an icom part # for that spring.? It is different than the others used in the unit.? I doubt that it is critical, given the large ground plane in that area that is screwed to the metal chassis.
