What is the amateur FM broadcasting legal limit?
<p>Some stereos can receive a signal just outside the commercial band at either end of 88 and 108. I legally can buy everything I need on eBay to transmit my own personal radio station. </p>

<p>What legal problems may I run into not having a license for while transmitting on low power just outside the commercial frequency ban. What are my limitations to transmit a prerecorded, remixed and non-profit music freely?</p>

<p>What legal problems might you run into?</p>

<p>Well, you'd be violating <a href="http://uscode.house.gov/view.xhtml?req=(title:47%20section:301%20edition:prelim)" rel="noreferrer">47 USC 301</a>, which requires a license for anyone broadcasting in the United States.  Penalties for that are given in <a href="http://uscode.house.gov/view.xhtml?req=(title:47%20section:501%20edition:prelim)" rel="noreferrer">47 USC 501</a> (a fine of up to $10,000 and up to a year in prison), <a href="http://uscode.house.gov/view.xhtml?req=(title:47%20section:502%20edition:prelim)" rel="noreferrer">47 USC 502</a> (an additional fine of $500 per day of violation), <a href="http://uscode.house.gov/view.xhtml?req=(title:47%20section:503%20edition:prelim)" rel="noreferrer">47 USC 501(b)(2)(D)</a> (forfeiture of up to $10,000 per day, with a maximum of $75,000), and <a href="http://uscode.house.gov/view.xhtml?req=(title:47%20section:510%20edition:prelim)" rel="noreferrer">47 USC 510</a> (forfeiture of your equipment).</p>

<p>"Just outside the FM band" on the low end (below 88 MHz) is television channel 6, while on the high end (above 108 MHz) are frequencies used for airplane navigation.  If your transmission interferes with a licensed user of channel 6, you're also in violation of <a href="http://uscode.house.gov/view.xhtml?req=(title:47%20section:333%20edition:prelim)" rel="noreferrer">47 USC 333</a>, which carries much the same penalties as violating section 301, but without the forfeiture of equipment.  If your transmission interferes with air navigation, you're in violation of <a href="http://uscode.house.gov/view.xhtml?req=(title:49%20section:46308%20edition:prelim)" rel="noreferrer">49 USC 46308</a>, which carries a penalty of up to five years in prison and a fine of up to $5,000.</p>

<p>Honestly, you'd be better off broadcasting <em>inside</em> the FM band: there, you can broadcast without a license under <a href="https://www.law.cornell.edu/cfr/text/47/part-15" rel="noreferrer">47 CFR 15</a>, which limits you to a broadcast power of <a href="https://www.law.cornell.edu/cfr/text/47/15.239" rel="noreferrer">250 microvolts per meter at 3 meters</a> (basically, you can broadcast to anyone in your house or maybe the next house over).</p>
