No not at all, however I haven't set up my own FM transmitter which could cause interference with licensed broadcast services for my neighbours or other radio services like
VOR beacons which broadcast from 108, just from the top end of the FM band, which is why Ofcom restrict power and location at the top end of the dial.
If I did, I would expect a chance of a complaint being made to Ofcom (especially if I was making a noise about a radio broadcast publicly and posting details about it telling people).
If Ofcom do investigate (as they do over in nearly 400 cases of illegal broadcasts a year), then I would expect a knock at the door. If as I'm not a trained broadcast engineer I screw up and cause interference or issues, that knock at the door might be with the police in the form of a raid. I could face criminal charges, fines and have all my equipment taken.
Luckily I am not knowingly running any illegal services, the only RF I'm running is at 2.4Ghz or 5.0Ghz in the form of Wifi (unlicensed spectrum), and 2100Mhz and 1800Mhz transceiver in the form of my mobile phone, that is unless a dodgy switch mode power supply is kicking out a bit of noise.
