-PWM Peripheral:
-******
-  The code uses the RPi PWM peripheral to time the frequency transitions
-  of the output clock. This peripheral is also used by the RPi sound system
-  and hence any sound events that occur during a WSPR transmission will
-  interfere with WSPR transmissions. Sound can be permanently disabled
