For some reason the results i get from ebnaut are different depending on signal bandwidth. For Stefan's latest 2970.1Hz transmission it is better to use 10Hz sample rate than 240Hz: 10Hz: sq5bpf@jitt
This is possible and quite common. For the carrier Eb/N0, the value of N0 is measured using the full bandwidth of the input signal. When the band is wider it may present a higher N0 because of things
