A Small LPFM Transmitter with Onboard Magnetic Loop Transmitter
As seen on my YouTube Page

 

 

This is the PCB board layout for a small LPFM transmitter that i'l showed on Youtube
This new design is even more powerfull , using 4 instead of 2 transistors
The range will go up to 2 kilometers or even 4 - 7 km using een external twinlead fed 300 ohm folded  dipol antenne
Or use just 2 transistors for  less  range  using a 100 Ohm Emitor resister instead of the 33 Ohm  for lower battery consumption
Take good notice by placing the transistors , for the BF 199 the connections are 1 Basis 2 Emittor 3 Collector
One set transistors is placed 180 degrees backward , be sure all the collectors are connected at the antenna loop

The PCB Layout , print this 10 x 15 cm on your printer to get the right printfolie for exposing your PCM material
