well mate, as my job description is broadcast technician, and i work in the field, the problem you seem to be getting has nothing to do with your end, it is actually the broadcast tower itself, now without seeing in person both your end and the broadcast site, i couldn't be much more help, the best answer i could give you would be to wait till tomorrow and see how things go, and to be honest, it is a little late at night
sorry i couldn't be of more help
