The data rate on an OOK (on off keying) waveform dictates how fast you have to turn a signal off and on. You can modify the waveform by shaping the ramp up and ramp down transition between the dwell times. As to power bandwidth, if you measure the power 500 Hz away from the carrier with 1 watt output and then again with 100 watts, your measurement will now be 20 dB higher. >>Uh, I was always under the impression that transmitted bandwidth is determined in digital modes by the data rate rather than power output. >>The "dirtier" the digital signal the greater bandwidth generated. Am I wrong? _______________________________________________ RTTY mailing list RTTY@contesting.com http://lists.contesting.com/mailman/listinfo/rtty |
