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 :)
