A. Low power licenses are for 8 years, like any other radio licenses. And, like all other radio licenses, there is a general expectation of renewal, which means that unless you have flagrantly and repeatedly violated fcc rules, you can pretty much expect that your license will be renewed forever.

There are two exceptions. If an adjacent full power station wants to modify its facilities, low power licenses have what is called "secondary status." This means that the full power station can ask for a power increase or change its antenna pattern and get an order from the lpfm to go off the air or modify its coverage. I don't expect this to be common, because most full power stations are already at the maximum coverage allowable to them under the terms of their licenses.

The other exception is where two or more groups applied for the same frequency, and they were tied for "preference points," and could not come to an agreement about time sharing. In that case the FCC will divide the license by the number of tied applicants and split the terms. For example, if there were four tied applicants, each would get the license for the frequency for two years. There is not any "expectation of renewal" in such a case.
