Two Transistor Reflex Radio
Design by G. W. Short  
Very few people listen to A.M. radio any more but, amazingly, at the time of writing, (about 16h30, 27/06/2017) there are still a few transmitters operating.  
For example: BBC Radio 4 on (long wave 198kHz), Europe 1 (long wave 183kHz), RTL (long wave 234kHz), Radio Alger (long wave 252kHz).  
You can easily find out the frequencies of stations transmitting near you...  
   
 
   
Transistors: BC109C or similar  
L1 and L2 are the antenna coils (see below).  
   
If you can't find a 1mH coil, you can make one by simply winding about 1 metre of thin wire around a piece of match-stick (or something similar).
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.
   
For a method of making simple printed circuit boards, like this one, see here.

I think I still have a few of these somewhere, if you can't find one...
