I ran a pirate station for a while until I found out the local FM classic rock station wanted to serve me a cease and desist. We only ran once a week for about 2 hours. So word spreads and people do come looking. We were running 5 watts and could clearly cover about a mile and a half radius around my house.
You would be better off buying one unless you know how to make transmitters from scratch most people buy them off a rig doctor www.ravedance.net

as long as it doesn't #1 transmit very far and #2 doesn't interfere with other equipment, it shouldn't draw any attention.

If you are in the USA, the FCC is one of the controling entities involved...

Regardless of popular misconceptions, it is not legal to broadcast on FM at low power, or at any power, without a license from the FCC. It doesn't matter if you are less than 100 watts or less than 1 watt. That is why the FCC has been trying to institute LPFM - to provide a legitimate license to very low power operations.

The only exception is that you are allowed to broadcast on FM without a license if your transmitter produces about 1/25th of a watt, or 25 milliwatts. This is only enough power to go about 100 feet, under the best conditions. It is actually not the power but the field strength that the FCC measures. The way the FCC checks for compliance with the law is whether you exceed a measurement of about 250 microvolts/meter on a field strength meter, which is a tool that is specifically designed to measure the strength of electromagnetic fields. This rule is designed not for broadcast transmitters, but more to allow for wireless microphones and similar devices. Because many garage door openers and computers accidentally exceed these limits, through poor design or breakdown of some sort, the fact is that FCC field agents actually spend very little of their time looking for illegal radio operators, but instead, are spending their days tracking down malfunctioning pieces of equipment like this that are inadvertently fouling up the electromagnetic spectrum.

Oh that is an excellent phrase 'inadvertently fouling up the electromagnetic spectrum' it sounds like the kind of crime I would commit...
Yep, the new "air polution" :-)
