Overall:

Eric 12/07/2020

Very tiny TX FM , very powerfull , with 2 LIPo in serie (8.0 volts) , , current is 33 mA , so electrical power is around 350 mW , considering an efficiency of 50% for this kind of simple TX, RF power is around 175mW , which is a lot. I used a dipole with 2 wire of 80 cm on 88.60Mhz, placed at 5 m above ground , and range was about 1 km around my house, checked using my car and driving around. amazing
