The advantages of FM modulation is free from the influence of air disturbance, the bandwidth (wide band) is larger, and the high fidelitas. If compared with the AM system.fm transmitter is a modification of the fm transmitter on the market (type of saturn s 038). with several series of modifications and additions boster series can produce power at around 12 watts

try in the series after this work is quite good, the signal generated is stable and strong enough
up time should not in a hurry to do directly, but overall do each part in sequence so that the error may be earlier
the first part of the work is in the oscillator, after the raft can try in turn to the way radio waves on the free and set the radio volume so clearly audible hissing sound. turn up the core koker hissing sound on the radio is missing, if you get a signal in a robust and stable means that the set of oscillator has been working with both.

the next section can start at the raft, after finished the second set trimer (C8 and C11) in the buffer in turn can power up in most large and most small SWR. If the series works well, will produce approximately 0.25 watt power
to get more resources than most can add more series boster 12 watt range, so the distance will be increased to reach 7-fold
