Hans Summers G0UPL Wins FDIM 2N2222A Power Out Challenge -- 4.1 Watts from Two 2N2222As

Farhan told me how cool this was.  And he was right.  It looks like a lot of fun.  Congratulations Hans! 



  1. Really enjoyed this Hans, and learnt plenty from it too! Greater presentation. 73 de M3KXZ

  2. Wonderful effort from Hans, just shows there's quite a bit of testing out amplifier theory in this challenge. Loved seeing the device under a clear perspex box, in case of 2N2222A spontaneous destruction.
