Hi,
As a prelude to various experimentations, I had to remove the RX filter on some C123. As this can be useful to others, I've done a little summary of how I do it. It's not for the faint of heart tough :)

Nice writeup!
Going at the shielding with a Dremel is a bit rough for my taste. I might have tried to use something like Chip Quik to desolder it.
I don't have experience with the product, but it looks like a good sensible method and the videos I've seen look fine.

I have removed some of those shieldings with a small caliper. The trick is to use the round holes and to seize the metal there. Then rotate the caliper and pull off stripes of metal like with a can opener. You just have to be careful on the soldered edges, since you can accidentially pull some copper off the top layer. With a little bit of wiggling the shielding will come off nicely.

My only comment would be: Please consider adding this to the OsmocomBB wiki rather than [just] your personal page :) It's good to have one central spot where we collect the information, I believe.
