I guess the important question is: where are you? As Rich said, you should start with your radio licensing authority to see what the requirements are for putting a station on the air. Most of us here are familiar with the FCC rules concerning low-power FM and Part-15 AM, but different countries have different laws regarding radio. I do know that New Zealand has an authorization similar to the US Part-15 rules which allow FM operation on specific frequencies at 500 mw. Great Britain has a low power service that allows limited community operation, but I don't know the requirements for getting a license or putting a station on the air.Good luck in getting your station on the air!FrankEast Hill Radio
