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
|
|
||||||
by editing /etc/modules and commenting out the snd-bcm2835 device.
