Apparently, there is an upgrade available for my AR7030, but the 2
spare filter sockets are used up in the process, meaning the one I
added would have to come out to make way for DRM, leaving only the 4
factory-fitted defaults available. Will need to think about it.

An extensive mod is not needed for the AR7030, since its "9.5 kHz"
position is wide enough. All that's needed is a downmixer with f_mix =
467 kHz to be attached to the receiver's 455 kHz IF output.
