Hello everybody,
I noticed that the default value for FM modulation index in Quisk is set equal to 1.67. I use Quisk with a Softrock RXTX. Is it a correct value? I assume that 1.67 comes from 5/3, where 5 is the frequency deviation of the transmitter and 3Khz is desired modulated bandwidth. Am I correct? Does the Softrock really has a 5Khz deviation? Would it be better to change the 1.67 value (I was thinking to set it equal to 1) to have a clearer modulation? As for my understanding lowering the modulation index setting to 1 would increase the modulated bandwidth up to 5Khz (instead of 3Khz).
