Premium Pilot
from what I have been able to find so far, tower can talk over you to other pilots and I haven't found a shred of evidence saying you need to be licensed to operate a radio and transmit on air traffic control frequencies for the purpose of communicating with the air traffic control tower using an approved radio that was built for that purpose.
Well I have given you a 'heads-up' that you are not authorized to operate on those frequencies.
