FT11 FM Transmitter,Portable FM Broadcast Transmitter for Church with Microphone, Rechargeable FM Radio Stereo Station for Drive-in Movie,Parking Lot,Support TF Card AUX Input

Absolutely incredible product! It's small enough to fit in your pocket. Transmits audio and a microphone to the radio. I use mine to run my mobile drive-in theatre, and it works flawlessly. I love this product so much, that the urge to buy another one, even though the original product is in perfect working order, (just in case) is strong. I do not understand how anyone could possibly be disappointed in this product. From the quality, to the price, what else do you need in a perfect product?

There are a lot of things to like about this device. - It is small compared to almost any other FM transmitter in its class And has a rechargeable 2000mAH battery that will power it for around 6 hours or more - The antenna screws into a reverse type SMA connector that may require an adapter to connect to regular SMA connectors - Using the SD card to play songs from can eliminate any hum problems as does the digital link over USB and you can set Random mode in SD play - The unit has a builtin mic you have to yell into to be heard and a separate mic input and comes with the external mic as well - It has a setting for Preemphasis of 75uS or 50uS. 75uS is used in the US but after trying both settings I can't hear any difference for whatever that is worth. - The overall sound quality is excellent, and hum free (actually best to keep antenna away from your other electronic equipment - like on the roof). - Lastly I measured the power output on this and found it was outputting 0mW on setting 0 and 1, then 230mW on setting 2, and 210mW on setting 3. I got so curious I bought a second one and measured it: - The second one outputs 0mW on 0, 191mW on 1, 330mW on 2 and 365mW on 3. Kind of nonsensically spaced power levels. So if you are trying to follow FCC rules - measure the power out of this thing and make sure it is under 100mW before connecting an outside antenna. - If you use the little antenna that comes with it, it is tuned for 91MHz +- 1MHz, and is a terrible antenna for the rest of the FM band - Controlling the device is dirt simple using the intuitive keypad Cons: - Did I mention it comes with a terrible antenna? - You won't know how much power it puts out unless you measure it.

I bought 2 because I thought it was a good overall value. Good signal strength, but a little dirty. It elevates the noise level in the FM band, more than it should, making reception of weak stations more difficult. Noise level is about -40 db or -50 db on the station close on the dial I decide to use. Ideally it should be around -60. Broadcast transmitters are usually closer to 70 db. The noise sounds alot like HD hash. I sometimes use it in my car too. For some reason one of the inputs on one of the units stopped working the other day. Not sure what going on. Microphone input is still working though.

We have found that this little inexpensive transmitter has a range of about a block in all directions (about 600 feet). It can be hung from a belt or the wrist. The included lavalier microphone does not distort the voice of the speaker. Apart from the microphone port there is a port allowing input of music and other audio files streamed on other devices such as an android or iphone. The quality of the original recording is not lost. We use three of these transmitters for our outdoor church services during the pandemic, one for the pastor, one for another speaker, such as the liturgist, and one for previously recorded music (hymns, anthem, prelude, postlude etc). The transmitter is very light, and its size means that speakers are not forced to stand in one place. We initially considered much more sophisticated broadcasting options but we are very satisfied with this simple and effective setup.

So what I think I'm figuring out here is this thing that had great coverage like almost a thousand feet it was awesome and then it started getting cold out and I do projection shows and it started getting crappy you had to be like right up on it to get a clear signal I'm very upset pisses me off at work fine but the cold weather does affect it guys and it doesn't recover. Okay so I have an update I'm posting this on here that the company has given me a full refund and that to me tells me that the company is serious about their product and I think I may end up buying another one maybe because it could have just been a fluke or could have been something I did who knows but the company has stand behind their product and giving me a full refund and to me that tells me the company serious so I'll definitely look into their future models because FM transmitters are always a necessity what I do when it comes to these projection shows

Extremely happy with this transmitter. In my tests, it appears to transmit to a range of 300-400 feet from the transmitter. Sound quality is good. This would be a great transmitter for a church, small drive-in theater, etc, but also would be great for protests and other such events. It also works great as a transmitter to use to port your music to your car stereo (as well as everyone in surrounding cars tuned into the same frequency). Also from what I can tell, this transmitter is Part 15 certified, which is important to stay in compliance with the FCC's Part 15 rules if you are going to be using this in the USA. So far, this is the best Part 15-compliant FM transmitter I have tested to date.

Used it for about 2 weeks. It worked , but I set it to 91.5, it took over the 91.3 radio station for a good 200 feet, taking out that station for possibly 20 houses. I accidently dropped it while trying to get a different station that wouldn't interfere. It stopped working. Only 1 drop while in my possession. It was at most a 3 foot drop. Very sad, worked hard to get my Christmas display up and can't find another transmitter to get delivered before the season. No more music this year.
