Legal Information

It is my intent to operate this non-licensed transmitter in compliance with Title 47 of the Code of Federal Regulations (CFR47) - part 2 & 15. Subparts a and b are the most relevant. Since I really don't want a visit from the FCC enforcement bureau I'm adhearing to these rules.  I have chosen the frequency of 100.1 which is based on FCC listings of licensed broadcasters in a 200km radius from our home, and by actual tests with a very sensitive FM receiver.  The maximum power allowed for a non- licensed transmitter is 100 milliwatts. Further limited to 25 milliwatts for the FM frequency band. The kit I soldered and constructed has a maximum output power of 25 milliwatts. I have further reduced its power output to 20 milliwatts to play it safe. The FCC has placed a limit of approximate 200' on the distance you can transmit. I've learned that weather can affect that figure a lot at times.


Interference / Infringement

If you believe you are experiencing any interference as a result of the operation of my transmitter and its transmissions, or have other comments, please send an email to webadmin@wowway dot biz I will cease transmissions immediately and work with you immediately to alleviate any problem.  All interference complaints will be taken very seriously as we do not intend to violate the rights of any licensed broadcaster or their listeners.


If you plan to use any of this information in conjunction with setting up your own FM transmitter, I've provided a list of some of the subparts of part 15 which I feel are important. These regulations must be followed in order to use a FM Transmitter.


1-19 apply to all.
17 Susceptibility to interference (you interfer with a broadcaster or receipient - look out).
23 Home built devices such as mine.
25 Use of kits (doesn't appear to be relevent since it pertains to TV's.
203 Antenna requirements.
209 Radiated emission limits. (ie. power output).
211 Ppower limits for transmitters.

Hardware

In order to keep my neighbors from burning down my house as a result of having to listen to the same christmas music blaring and repeating itself over and over again with the use of loud speakers placed in the yard, I've purchased a FM30-B Stereo Broadcast Transmitter in kit form. The current song is then broadcast over your vehicle FM radio. This unit has been performing absolutely perfectly with no down time since I built it in 2008. One of my biggest concerns prior to purchase was selection of a unit that would prevent me from violating the FCC - Part 15 regulations which govern FM transmitters. This unit does not require a license to operate.

Before each season starts, I verify that my FM frequency 100.1 is still ok to use. And so far I've been able to use it every year since I started back in 2008.

Rant

Once upon a day I had a link here to the Ramsey Electronics website where I purchased my kit. But they have ceased their sales of kits like this fm transmitter and other neat educational kits that have been used to teach electronics to a large number of citizens like maybe you and me. They've shut down their sales of kits most likely because of the raid on their business by our government. The search warrant according to some sources had mentioned the sales of kits or items like clocks that have embedded microphones and cameras in them. I've learned alot about electronics from the assembly of various kits. The most challenging kit was the Heathkit Oscilloscope. I've assembled nearly all of my christmas light controllers as well as a variety of other gadgets over the years. I'm surprised that our government hasn't Amazon for making Alexis, a system that listens in to our conversations. I don't know if there are any FM transmitters kits to be found.
