None of the Chinese el cheapo radios that I know of are ready to use. All require programming by somebody knowledgeable or ready to learn. Yes, you would both need, at the very least, amateur Technician licenses to use these legally. If set up correctly with the 14 frs channels someone could hide the fact they were using a non approved radio. Using the programmed test channels will make you stand out like a sore thumb. Who knows what they are used for in your area? For sure, if you interfere with public safety they will find you. If it is a business or amateur they will eventualy track you down, the HAMS will do it themselves and have fun doing it. I would just use the Dakota Alert MURS radios as that service allows driveway alarms, intercoms, etc.
