0.5W FM Transmitter for Church Parking Lot - FCC Certified Long Range Stereo Mini Radio Station for Drive-in Movie, Fireworks Show, and Outdoor Events

My old fm transmitter broke after 6 years. bought this because it was cheap and in stock. I use it for my Halloween and Christmas display. Not as strong in power as my old one. but it does the job.

Bought this to broadcast throughout one of the dormitories, and it's perfect. It's range is a little broader than advertised and it works perfectly.

It doesn't have a standard BNC connector so I have to buy an adapter now to connect it to anything else I own. The one I bought in 2013 that finally broke down, had the BNC.

When it did work the sound was horrible and very poor transmission. Lots of static and dead air. Then it just stopped working only a year after purchasing. And I only used it about 5 times in that year.

This worked out great for a Holiday Light Show. Super simple to use.

The description says this is FCC part 15 certified but when I looked up the FCC ID on the side of the unit (2ASVO05B-73) in the FCC database the certification was for part 73. Broadcasting with part 73 equipment would require a license and could land one in very hot water in the case of an FCC investigation.I returned this and ordered an externally identical unit with an FCC ID (2ASVO05B7CT200) that is part 15 certified and therefore does not require a license.

This is like having my own personal radio station in my own home and actually, my whole apartment complex. This small little black box is really a secret radio station. I hooked it to my computer and set the frequency and I was away! You can choose a frequency of your choice within the whole 76 through 108 MHz band. The lower end is not much used in America so it is generally open and waiting. Regular FM stations can be found in the range of 88–108 megahertz (MHz) and you can find a space, a quiet spot in that range where there are no commercial stations broadcasting to set up your own station. I have lots of radios and some, but not all of them, can access the lower 76 to 87 MHz range so I have this whole space to myself. Which is real fun. Where Bluetooth is often limited to 10 meters (or about 33 feet) which is nice within my apartment, with this FM radio station maker I can listen to my computer, or whatever I choose to plug in with the included 3.5mm standard input cable, I can listen on my FM radio anywhere in my apartment complex all the way to the pool or tennis court. I may be able to get a signal maybe a half a mile or so, I figure. If I was better situated in the building I could beam my station way farther. But as it is now, I am really impressed with how far I can get a good signal from my computer to the world within my home and outside too.It is so simple to work. First attach the antenna. This is very important and is mentioned in the instructions. But should be printed in red because if you turn it on without the antenna attached you will quickly burn it out as the broadcast energy has no place to go and poof!! your radio station will go dark and dead. So hook up that antenna right out of the box. It twists on easy. Then you are ready to go just push the on button, two little buttons go up and down the frequency range to set the station for your radio to pick up and set your volume. Done. Plug in the nice heavy duty standard input cable that goes from the output of your source, in my case, my computer, But you can use your iPod or whatever, or use the microphone input and you are broadcasting. So easy, so simple and so so much greater range than you ever could go wireless before. This is fun. I suppose it is for drive-in movie theaters or church sermons or something. But for me, I can be my own DJ and send the music or whatever I choose into the air. I am having fun and it was not expensive. This thing is cool. It works.

This transmitter functions adequately for voice. It is low latency and can produce a reasonable volume, but there is static (clicking noises) that can be heard on the output. It may be related to grounding issues or may otherwise be related to the power supply, so it may differ depending on where it's plugged in or how it's powered. In my tests it is present even when no audio input is connected - I could not get rid of the noise. It might be possible to reduce or eliminate it by adding RF filters to the power input line or running it from a battery, but I couldn't figure it out. It's not overwhelming, but would be annoying if used for a concert or where high fidelity audio is desired. I wanted to use this for an ad-hoc drive-in movie setup in a field, the noise may or may not be too disruptive for that, but there are other issues preventing me from using it at all.The real problem is that it is not Part 15 compliant at all. I am in the United States and this is being sold to people in the United States as being FCC Part 15 compliant, which means that it should be legal to use without a license. The FCC ID is actually listed as part 73, nowhere in the FCC filings does it mention part 15. That is not what it is was evaluated under by the FCC and it is not how it got that ID - that's a big deal for me and other customers because it's the difference between being able to plug it in and turn it on without violating the law vs being potentially subject to major fines. I can not use this legally. It's not just a minor technical difference either. The power this thing puts out is orders of magnitude higher than is allowed by Part 15, even on the LOW setting. There is no way to use this legally without applying for and being granted a license by the FCC to operate on a specific frequency and it should not be presented otherwise.It does allow you to limit the frequency range that it can be tuned to in the settings, which makes sense because if you do apply for an appropriate license you would be granted use of a specific frequency. I just wish it had a power setting low enough to be legal without a license - AKA Part 15.
