Marcel,
You have probably blown the speaker amplifier chip, U1 on the DSP
Board. Many of us have had the same problem. Elecraft has not
been able to determine the cause of the failures, so they have
not provided a solution.
The part is inexpensive, but is very difficult to replace because
the pins are very close together. If you know an excellent
soldering technician, maybe they could do it for you. Otherwise,
you have to send the radio, or just the DSP Board, for repair.
