The voices... upon turning one of the knobs, have changed to strange and angry musical incantations and pleas for me to purchase automobiles... I still have not deciphered the full realm of possible intentions of this being, which identifies itself as "WNNX 99.7," but I have so far learned that I shall be rewarded greatly for my dedication to his (its?) spirit if I can somehow become this "Caller #19." My investigations will continue in the coming days...
