Transistors: BC109C |

L1/L2 are the antenna coils |
| |
If you can't find a 1mH coil (often called a "choke") you
can make one by simply winding about 1 metre of thin wire around a piece of match-stick (or something similar). |
N.B. |
Solder the resistors first, then the capacitors, then the
coil, then finally, the diode and transistors. This reduces the risk of damage to transistors and diode
through overheating.
