Learning a few new things. I saved two Shure ULX-D digital microphone sets with body packs and lapel microphones from going to waste, but as the receivers were rack mounted, the sets came without antennae and power bricks, which I now need to source :) Same with the power brick for the charger thingy. And I guess the battery packs will need replacements too. But this will be a welcome addition to my studio :)
