@B. Dean Berry can tell you specific models, but you can get old Fire Dept type pagers that will detect the tone and kick the pager on for the wx band audio. I want to say there are some Motorola and Kenwood models that are perfect for this purpose, I just can't remember exactly what models off the top of my head.
FYI Ethan, this does absolutely belong in equipment. So the OP is good here. It's exactly where we would direct him on the Discord as well.
