I am in the United States.
The title pretty much says it all. I am really into to building transmitters. It's even more fun for me than using them. I really have a lot of skills and would like to sell my own broadcast transmitters. Yes, I have a spectrum analyzer and can check to make sure they comply with specifications.
I understand that there is compliance testing that would have to be done (IE the transmitter would need to be sent to a lab for specification testing, etc.). This part I am pretty sure on, however I have no idea whether I need a license to build such transmitters or can I just contact some testing house and if it passes, I have a licensed transmitter. Is it that simple or do I need other licenses?
Also, the name of any testing facilities would be appreciated, but that is outside the scope of the question.
