You can increase the output of the FM05TX ASPISYS PLL BOARD up to >850mW by simply follow the next three steps:
a)Replace the Q1 transistor with an IRF510 MOSFET
The IRF 510 will be fitted as the transistor.
b)Replace the R46 resistor with a 15k 1% 1/2W
c)Replace the R40 & R43 with 4,7Ohm 1/2W
This will increase your power at >850mW over the entire FM Broadcast band (87.5-108MHz)
