7W 1W Long Range FM Transmitter with LCD & 3.5mm Audio Cable - Ideal for Drive-in Church, School & Supermarket Events, Light Shows & Fireworks Display - Black

Sender stört sich selbst, Eingang nicht gegen HF geschirmt, extreme Rückkopplung.

funciona muy bien lo uso para mi iglesia, pero rompí por accidente la antena ¿hay refacción?

This FM transmitter works great! The sound quality is amazing! The range also goes well beyond what anyone would need it for! I’d say it’s a great value for your money and extremely easy to use! Perfect for hobbyists 😌

There are several version of these FM transmitters on Amazon. This version is the more powerful unit (1 watt or 7 watts). One watt is more than enough around the house. You want the telescoping antenna instead of the rubber duck most use. Has a cooling fan. Uses an FM synth chip. Seems well designed and well made. I'm feeding it from a PC. You will have to lower the PC's volume to prevent distortion. There isn't any visual indication of the proper volume, but with a decent radio, you can figure it out (basically turn it up to the point where you get good reception (loud) but not so much that the loud parts cause distortion. Fidelity seems to be as good as the receiver allows. Can interfere with USB/Bluetooth if it's too close to the PC. All of these FM transmitters will distort badly if fed a too strong audio signal. For the highest quality sound, get the Sound Lock (free) audio limiter app (Windows) which can be set to limit the volume of the audio signal the PC puts out and avoid distortion. Basically you listen on a nearby FM radio and up the maximum volume allowed until distortion is heard, then back off. Note: These types of FM transmitters don't put out a strong enough signal for good operation with analog tuned FM radios (like the old school pocket radios). You need to use a digital receiver so you can directly input the frequency being used. A popular frequency that should be clear in most areas (except LA and a few others) is 87.7 mHz. That's the frequency of the audio on the old analog TV channel 6. Only a few of those are still on the air on that frequency. While this is not strictly in the FM band, most FM receivers can be tuned to it.

Performance is very good. The only thing that prevented it from getting 5 stars across the board was the volume output control. There is no visual indicator to show you when you have gone too far and are into distortion land. You have to play with it on a receiver to find the sweet spot (not too soft to hear/not too loud to distort). But once you find the sweet spot, it sounds surprisingly good for something that was only 80 bucks. I have the 1 watt/7 watt version. 1 watt goes about 3 quarters of a mile. 7 watts goes about a mile and a half. Unit was just on the kitchen table on the first floor, so if you elevate it, you could probably do better. Seems more than adequate for a drive-in movie lot or church purposes. Best to use it on 87.9 or 87.7 where it won't interfere with anything.
