They are not illegal. These are Part-15 devices and require no licensing.
Incorrect. Part 15 specifically excludes the TV bands. Microphones in the TV bands technically require a license, which the FCC has not been enforcing because no one complains.
Their very narrow bandwidth signal, low power, the facts that (up until DTV) it was easy to set them to an unused channel and they aren't generally used in residential areas, all mean TV interference was minimal.
None of this is true of WSDs except the low power (until the WSD is hacked, amplified or connected to a high-gain antenna).--
