Generically LPFM could mean something like a part 15 transmitter that would
work for cars in a parking lot, but the term is also a specific FCC license
class up to 100 watts ERP.

For the FCC's LPFM there is not a filing window to get a
license/construction permit and the last one was in 2013.

But maybe we can get Congress to get the FCC to create a new one due to
this crisis.
