If a transceiver such as the BaoFeng UV-5R is used to transmit over FRS/GMRS frequencies (unlicensed), it is illegal in the United States due to FCC regulations that state that the power must be <0.5W and that the radio must not have a detachable antenna (the UV-5R is rated up to 5W and has a detachable antenna). Realistically, though, I am wondering if and how the FCC actually enforces this?
For instance, if two people decided to use these as high power "walkie talkies", and were careful to select unused frequencies, didn't disrupt other peoples' communications, didn't communicate from home/work (i.e. a static location that identified the person transmitting), and changed frequencies regularly, my questions are:
1) I understand the law, but is it actually enforced? Do they even waste resources trying to catch people doing this if there is no disruption occuring? Are there any documented cases of the FCC actually tracking down and harassing/fining/jailing people for illegal FRS/GMRS transmissions of this sort?
2) How would the FCC actually track down this sort of sporadic, non-disruptive transmission from multiple locations? I understand the concept of triangulation of radio signals, but how is this actually achieved on a nationwide scale and in a way that can promptly lead them to the location of the transmission (so that they can fine/arrest someone)? Are there passive monitoring systems in place in urban areas that can automatically/instantly detect illegal transmissions? Black helicopters with FCC agents flying around hunting for illegal walkie-talkie usage? etc :) What does their tracking technology actually look like nowadays, and what kind of capabilities does it have that would enable tracking this type of transmission?
3) Are there any sorts of identifying signals (some sort of unique identifier) that handheld transceivers such as these emit while transmitting, that allow for the instant identification of the device? (i.e. something akin to an IMEI # for cell phones)
