CW beacon
The WPM rate of the Morse is varied as the solar panel voltage varies. At high solar voltage the Morse WPM is reduced, and at low solar voltage it is speeded up. So by listening to the FM Morse you can tell if the solar voltage is high or low. In addition at low solar volts where the battery charge is expected to be low also, the faster Morse uses less power. At 2500mV from the solar panels the delay value used for the Morse dit period is 50mS, this gives a WPM rate of approx 24WPM. At 4500mV from the solar panels the delay value used for the Morse dit period is 100mS, this gives a WPM rate of 12WPM.
