Re: Its very easy to detect ground based broadcasts
They could simply have drones overflying and listening on those frequencies, and it would be easy to pinpoint the locations that are transmitting. Send round the police and put them in a "re-education" camp for a few years, and there will be very few willing to run the risk.
Though jamming may be an easier solution, at least within major cities.
