It works!!!
The pll locks now!!! The problem was the burned TSA5511! I ordered a new one, I put it on the board an now the pll locks and I can hear the signal on a radio!
However there is a problem: If it gets locked, it never unlocks! When it locks, if I remove the coil from the board, the display and the green led show that the transmitter is still locked, although I can't hear the signal on the radio! That's because I've removed the coil! Is this normal?? I have tried 3 different hex files.............
Furthermore I hear an awful sound on the radio when it is locked, something like a helicopter... By adjusting the coil, the sound changes frequency and sometimes is just a constant sound signal...... What is this??
Thank you for your help till now! :-D
