transmisor FM "30 - 40 watts" de bajo costo $$$

A Chinese FM transmitter is being sold with a claimed maximum power output of 30 to 40 watts, which is not accurate. Testing at frequencies from 76 to 108 MHz, the highest power output achieved using the maximum supply voltage of 13.8 volts was 28 watts, risking damage to components by operating at the transmitter's maximum voltage.
