Send broadcast quality audio from your mobile phone or any audio device to any nearby FM radio!

The FM Transmitter-2 uses common FM radio waves to send sound from any device you choose to any nearby FM radio or stereo system. The only wire you have to connect is from the FM Transmitter to a headphone jack. You can use it with your iPhone, WiFi internet radio or even your satellite radio. One of the unsung qualities of C. Crane's Digital FM Transmitter-2 is its extreme versatility. While most people use it to send music from their computers or MP3 players to a nearby radio, some customers have told us how they use it with their guitars, portable DVD players or iPod (a lot of fun in cars) and even other radios.

It has a thumbwheel that allows you to adjust the input for perfect audio quality and a two-level LED indicator to help set optimal signal level. It broadcasts clean, very high fidelity stereo audio.

Maximum distance is about 45 feet line of sight with no obstructions. Broadcast distance will vary depending on your location (see FAQs for more details). AC adapter included, or runs on two AA batteries (not included). FCC compliant. Choose any FM frequency between 88.3 MHz and 107.7 MHz. Portable, fits in the palm of your hand.

Weight: 5.8 oz. Size 3" W x 3.5" H x 1" D. (Patent # US D483,024S)

I bought this so I could listen to the Olympics while working in my shop wearing ear protection with AM/FM radio capability. The website listed several vacant FM radio stations and other great and good stations on which to listen to the FM broadcast for my zip code. Clearly they did not take in consideration that it is near the Canadian Border. The vacant stations are not vacant and I have been unable to find a station that was clear enough that I could get more than 30' away and still get good reception. Very disappointed.

Version 2 is so much more efficient than the version 1 that I have owned for several year and loved. Being hard of hearing, I use the transmitter to send the TV audio to my CC Packet Radio so I can set my sound levels and my wife can adjust the TV sound to her own excellent hearing comfort (or mute the TV altogether and let me alone listen. First Version 2 I got failed after a little more than 24 hours of operation, but the second has been excellent for the past 10 months. Love it... can hear the TV audio anywhere in the house and in most of the back yard (Much greater range than the first version)... crystal clear. Recommend.

ABSOLUTELY DISAPPOINTED!!!! Not impressed at all with this the $17 competitors product that is now selling on sites for over $100 if you can even find one is way better! Range on transmitter is less than 10ft,power is horrible. Even on a clear channel other stations over power it. I am really un happy because usually ccrane stuff is superb, not this one! The other transmitter I have made by some other company is 1000% better. I've had it for 2years now and I was on a trip earlier this year and was traveling in a 2 car caravan and could pick up broadcast from lead car about 500 yards away! Too bad I can't get another one of these but they are sold out everywhere!

Sound quality very good, in fact as good as the commercial stations with low background noise and can get to the volume of other FM stations with a very minimum of distortion. Understand from another review on a part 15 forum site that this has some compression which is a good feature! While this needs 2 mods to make it into a "real transmitter" it doesn't work like my 1 watt transmitter does, but for something portable that can work on batteries it's a great transmitter! Gave a 4 out of 5 because of mods needed to make it better. The mods allow me, in Canada to take full advantage of the higher signal strength allowed here.Mark

This is the best FM Transmitter I have found commercially available.I want to find one a little more powerful. Probably won't happen.

Very nice, I am very impressed. Sounds great and well designed, and I'm a pretty picky guy when it comes to audio gadgets.I tune all my radios in the house to the FM2 which is plugged into my iPad. Podcasts, music, audio books, whatever I want to listen to as I move around the house.

This is my second C.Crane Trnsmitter. It's excellent!With a wire attached to the antenna, I can drive away out of view of my house and still hear my station!What a great sound. I use it on my pc for streaming talk radio, and Old time Radio off the internet.My station sounds as big and strong as the big boys.

Works well. I like to use it to broadcast internet-based broadcasts from my computer to radios throughout my house. If you live in a large city, it might be hard to find vacant FM frequencies without bleed-through, but works well for me.

  • How far will the FM Transmitter 2 transmit?

    The range will vary depending on several factors:

    • The number of FM Stations in your area (see search tool below)
    • The quality of the FM receiver and antenna
    • The number of walls the signal needs to travel through
    • The types of walls (wood, metal, sheet rock, stucco, etc.)

    The output power of the FM Transmitter 2 is set to the maximum limit specified by the FCC. Most of our customers achieve 40 - 60 feet depending on their situation. The signal will travel up to 70' under good conditions. The FM Transmitter-2 will work better in a noise free environment. In a noisy environment (such as one with lots of FM and computer noise) you can expect less range. We recommend extending the FM transmitter-2 input cable away from the computer (or any other RF noisy device) when connected.

    In open environments with minimal radio noise, the range of an FM transmitter can be easily increased by attaching a length of wire to the telescoping whip antenna of the FM transmitter. In our experiment, we attached a 31-inch length of wire to the whip antenna of an FM transmitter using an alligator clip (Any wire will work. Any clip that secures the wire to the transmitter's antenna will work).

    We attached the other end of the wire to a PVC pipe to keep the wire vertically oriented. We could have used a regular thumb tack, a stationery clip, or just about anything to pin the end of the wire up vertically.

    As the end user, you can search the internet on ways to increase the range for many electronic devices. If you are are having range problems, feel free to Contact Us.

  • What is the Broadcast Power for the FM Transmitter 2?

    250 µV @ 3 meters. It is the maximum allowed by the FCC.
  • Is the FM Transmitter 2 legal?

    Yes. It is certified by the FCC.
  • Does the FM Transmitter 2 broadcast in FM stereo?

    Yes, if you are transmitting from a stereo device.
  • Can I use the FM Transmitter 2 to transmit directly off a microphone?

    Yes, but it must be a self-powered microphone (one that uses a battery to power the mic).
  • Can I use rechargeable batteries in my FM Transmitter 2?

    Any batteries can be used but transmitting range may not be as far because rechargeable batteries are generally lower voltage.
  • How long will a fresh set of AA Alkaline batteries power the FM Transmitter 2?

    A set of AA Alkaline batteries rated at 2500 mAh would provide roughly 110 hours of runtime.
  • How long is the AC adapter cord for the FM Transmitter 2?

    The cord is 6 feet long.
  • Does the C. Crane FM Transmitter 2 use a Phase Lock Loop (PLL) circuit?

    Yes.
  • What is a Phase Lock Loop (PLL) circuit?

    A Phase Lock Loop is a circuit that locks onto the frequency selected and keeps the signal from jumping to other frequencies.
  • Will the FM Transmitter 2 turn back on automatically after a power outage?

    If you are using the AC power adapter with the FM Transmitter 2 and have batteries inside (that are good), the loss of power (such as a power outage) and gain of power will not shut the unit off.
  • Is the audio input on the transmitter analog or digital?

    The audio input is analog which is used by most radios, televisions, computers, smartphones, and other electronics. Some newer televisions and stereo systems use digital audio outputs. Digital output would not be compatible but there are adapters (available elsewhere) that can convert the digital signals to analog.

  • This WiFi Antenna is hands down the best. It allows me to connect to a business almost a half mile away. Two months time and this baby paid for itself. I am a very happy with my purchase.
    — John A., Mill Valley, CA
  • This radio deserves five stars because it sounds great, the ease of use and preset stations. This radio will become your favorite radio, also backed by great customer service if ever needed, thank you very much.
    — Pete P., Santa Rosa, CA
  • This is an excellent internet radio. I have had the unit playing constantly from the time I received it. Excellent sound for such a small unit and the remote works wonderfully.
    — James H., Richmond, BC
  • Good sound, lightweight and comfortable; not too tight on the head. I like one feature; it doesn't tell you where to place the speakers, left side or right side.
    — Harry W., Manassas, VA
  • I purchase this product specifically for AM recordings and it has worked superbly. I wanted to wait awhile before I gave my opinion on the product. It has worded exactly as advertised and more.
    — Jack L., San Pedro, CA
  • Very nice, economical home lighting. If you're used to the white light of fluorescent bulb replacements, these will offer the same type with no toxic ingredients or damaging UV radiation.
    — Gary B., San Francisco, CA
  • This antenna does work well; however placement and the shape you have it bent into is very important. I live about 70 miles away from Toronto and receive a lot of Toronto FM stations static free with the FM reflect.
    — Thomas S., Buffalo, NY
  • I'm not sure how I gone this far in life without it. I just love it. The best sound ever from an AM radio.
    — James G., Springfield, MA
  • This device is awesome. As a contractor, I can not access my customer's network for security reasons. Now, with my office on the second floor, I can connect to a WiFi hotspot 1.5 miles away and my signal strength is strong!
    — Robert S., Tabernacle, NJ
  • I just received my EP radio yesterday. I'm totally impressed with the old school simplicity and the modern day sound quality. Thank you, C.Crane!

  • This radio is wonderful. Small but powerful. Several years of service and no problems.
    — William B., Litchfield, IL
  • Just received this little jewel... did not open the manual and I was listening to NPR within minutes... no kidding. I'm a radio guy and the audio is great and look forward to a lot of great listening.
