I have been wondering about this for decades:
Why do TV stations use translators?
In the Seattle area several, but not all, the local TV stations use translators. What is the purpose and why are the translators channels all over the map? Example, local Fox Channel 13
also use 14, 25, 28, 43 and 7. And channel 7 is already in use by the local CBS station. If the goal is to be a repeater, why not simply stick with the Channel 13 in those areas where they are repeating the OTA signal?
