jup, steht eh im Manual:
The duty cycle of this radio is 10% averaged over the period of 1 hour. Meaning, if the next transmission will push the running average duty cycle over the 10% limit, the module will not
transmit until enough time has elapsed to stay under the duty cycle.
Because of heat restraints of the module, a 10% duty cycle over the period of 1 second will be
enforced after the measured temperature of the module rises above 60°C.
