I'm Andrew from Romania and i have a problem with this emitter.
I have made the all circuit but instead of 3,2Mhz crystal i used 3,2768Mhz, and it worked fine with the exception of broadcasting on a wrong frequency but not that is now the problem. The problem is, after i have remade a soldering on the coil, near the BF981 the transmitter refused to lock the frequency. I have replaced the BF981, the TSA5511 and even the PIC, but still doesn't lock. It locks the frequency if i touch the 4 or 5 pin on TSA5511, the green led lights up but it doesn't emit.
What can be the problem? i have replaced all the important components and still nothing...
