FM Radio Transmitter Solder Project Kit with Audio Lavalier Microphone Soldering DIY Kit for Electronics Practicing Learning, 87-108MHz

Does work as intended. The antenna really is the weakest part of this kit. The screw and bold don't really do much to help it keep in contact with the PCB. This is a pretty weak transmitter so the antenna contact is going to be very important. Other than that there is a little bit of assembly skill attaching the antenna and battery pack. For solder practice I would get other kits because this is pretty minimal in soldering. There aren't many parts to identify and time of build is very quick. If you want a fm transmitter at the end then go for it.

This kit was easy to assemble. The printed instruction were a bit small and the PC board is also small so it might be nice to have a larger PC diagram to make the parts locations easier to see. I could have printed a pdf on a full size page but I was able to manage.All of the active electronic chips are pre-soldered except the LED digital display.My problem is that despite soldering everything correctly I don't get any sign of life from the module. I will contact tech support to see what they say.......Tech support has been helpful to try and resolver the problem and they respond quickly. I would like to try some of the other kits Vogurtime. I like the way the kit is constructed.But after some troubleshooting tips from Vigurtime tech support they decided the problem was too difficult and refunded my money. I will probably buy another one, although I might buy one of the other kits, like the piano or AM/FM receiver. The piano looks like a lot of soldering but I would guess with the clear instructions not really very hard to assemble.

This is a fun kit to assemble and use. It broadcasts up to 100 feet. You can choose the channel that it broadcasts on. It is rather finicky for when you turn it on and the receiving radio (not included). Sometimes the receiving radio doesn't hear from it. I have about an 80% success rate.

I got this because I wanted it as my first real project that could be practical. My first kit was missing parts so this became my first. Got it today took me less than 2 hours to assemble. The range is like 20' in my basement (most like this is like .1w) and it sound really clear. Will take it out later to open air to see what it can do there. If you make a directional receiving antenna, this could have some real range.

Great introduction to radio electronics and soldering.Works as described.Signal travels farther than expected.a premade case would be nice.

This was a nice and easy assembly. For the price, you simply cannot beat it! It worked perfectly the first time I threw the switch. Works well enough to "Broadcast" old Casey Kasem Top 40 shows and the like to my stereo in the same room. Works at a distance up to about 10 feet.

This item was great in training with how to solder. Problem is, the directions suck. They don’t help and the pictures are quite bad at displaying much. Without my past experience and knowledge of electronics, I might have not been able to build this. Also this is a Transmitter not a receiver. Know what you are buying. You can’t hear anything out of this. You’d have to get their own receiver or have a small FM/AM radio with you.

Bought this a little over a month ago, and finally got a chance to put it together. Not my first project by a long shot, but thought it'd be a neat one to do some more soldering. Got it all put together, turned it on, and the LCD display didn't work. Checked voltage and resistance throughout the circuit, and all the math adds up. Pulled out my spectrum analyzer, and saw no new signals in the FM band. Analyzed a little more, and found it transmitting at 184 MHz. When I demodulated it, no sound was being transmitted. Definitely not going to work for anything I'd need to use it for.
