Fun to build. First I found a build video and then the instructions in English. They were not necessary. I only wanted to know what resistor and capacitor would be needed to enable a beep function for Morris code. I made two and they both work equally poor. After playing with the tuning I was getting better sound but broke off the speaker coil tab with the stiff wires included putting it back in the housing so I did not get to test the range after adjusting the tuning. The frequency is close to my old cordless phones I still use and it is what makes them most interesting.
