I may have missed it but I didn't see if you have an amateur radio license. Transmitting RF is regulated, and licensing is how the regulatory agencies control it. An amateur radio license permits transmitting RF in certain bands using type accepted equipment or equipment designed or built by the amateur. A license is granted after passing a test, the purpose of which is to give at least at start in understanding what the limitations and privileges are, and how to exercise them without straying from the regulations and causing harmful interference.
