I was going to come throw things at you radio people! So this comment is good. Since arriving the radio has been beeping once an hour.

During the ninth day, they will notice it beeping more regularly, and if they fiddle with it enough to get to the right frequency they will hear a pattern emerge.

It looks like Roland has the radio with him in the tag he threw at the npc starter so we can go deeper there if you two want to join forces
