Fácil de montar e funciona, embora não a 70 mhz, você pode afinar um pouco espalhando L1 e o alcance é de apenas 10 metros ou mais. Fiz um buraco na tampa para a antena.

Easy to assemble and works although not at 70mhz, you can tune it a bit by spreading L1 and the range is only 10 meters or so. I drilled a hole in the lid for the antenna.

Another neat little project board to play with for learning about electronics and radios. Quick and simple to build and a core of other projects and experiements. Two minor points to note: 1) The default frequency is about 80 MHz, not 70 MHz (I have built five of these so far and measured them with the GOOIT GY-560 50 MHz to 2,4 GHz Frequency counter.) 2) In the circuit diagram uses the wrong symbol for the inductor, L1. The symbol used is for a variable, iron cored inductor. Please see the attached picture. Still, 5/5 for this kit :)

I will be enjoying to make kit with my gound sun. I will recieve and talk useing my mobilephone.

Worked first time. Very easy to build and with good clear instructions, ideal for a beginner to electronic and radios. I bought three: One to build as is an the other two to experiment with.

Llegó rapido y economico, ideal para iniciación a la electronica.

With my 45 years of experience in electronics I tried this and sorry to say that it does not work
