"Once all the resources and references and compiled building a station is easy!"
How I did it: While the station built was for a public school campus, the same principles apply whether it's for a high school or university / college campus, a hobby diversion or business venture. Pulling all the resources together was the initial challenge. Much of the information I initially found on the internet was either poorly written and not very well organized. Having the proper information at-hand will keep you legal from the start.
First is find a frequency on the band you wish to transmit on (AM or FM) that does not have a station operating on it. This is probably the biggest challenge in an urban environment since most of the radio spectrum is occupied with commercial broadcasters.
Defining the goals of the station was the next thing. The goals will pretty much tell you where you have to spend your money on equipment and allow you to create a working budget. You can then figure out how much and what kind of equipment to use for your station build.
With your budget in place you can start to build your station. Depending on the situation, Part 15 compliant transmitters and transmission systems may cost as little as $20 upward to many thousands of dollars depending if you're building a hobby station or one to cover a typical college campus. Remember to stay within your budget and only splurge on the items that give you the most benefit for your particular needs.
While hobbyists will opt for inexpensive equipment (mixer, microphones, cd players, etc) which can usually be purchased at a local hi-fi and musician's supply store, professional equipment will most likely need to be mail ordered from higher-end suppliers. Most Part 15 complaint transmitters can be mail ordered as well as associated sub-systems in the case of campus-limited radio systems
Hobbyists are encouraged to purchase Part 15 certified transmitters for peace of mind and to be certain they are indeed operating within legal limits. Kit transmitters can encourage personal enrichment of electronics but do not offer FCC certification, which may be nice should you receive a complaint that warrants a visit from an FCC field agent.
Campus stations utilizing advanced transmission techniques (i.e, carrier current, radiating coaxial cable, free radiating antennas, etc) may need to have consulting engineers check and certify the "as-built" installation for FCC compliance. Certification by a professional engineer should be kept and made available should an FCC field agent make an inspection due to an interference complaint.
Do not bother the FCC with your Part 15 station. They do not have any procedures to deal with Part 15 station operators. They will contact you should they need to (i.e.,, interference, etc).
Lessons & tips: Be organized, define your goals, stay within your budget, only purchase equipment that allows you to operate and remain compliant with the FCC regulations and have some fun!
Resources: Having seen there wasn't one comprehensive resource available I decided to build an online resource for Part 15 radio broadcast enthusiasts.
CampusBroadcaster.net and
HobbyBroadcaster.net are online technical and reference web sites to assist anybody interested in Part 15 radio broadcasting on the AM and/or FM bands. Detailed information includes informative how-to's, comprehensive technical and legal references, station directory with featured broadcaster profiles, equipment reviews and an online community forum for sharing tips and advice.
