I understand why WNTN has to move because of land values, but why do they have to decrease daytime power from 10 kW to 0.75 kW? Interference with someone? To save money since they are closer to target audience? I wonder if they will be changing call letters since the NTN = Newton no longer will apply.
If the final format is Spanish-language, they'll probably identify with a slogan (preferably shouted, and with plenty of reverb) -- La Mega, Radio Colosal, etc. -- and minimize the use of call letters, to go with the practice preferred by stations in the homelands of their listeners.
