Content preview: Hi Jim, My ERP was in the range of 500 uW. I suggest to monitor the signal on 11904.7619 Hz, just to check that your system is stable over a longer time. This test is very useful. But you'll need the ultra stable reference signal because a PC clock drifts to much! If you do not have a reference signal, some tests using NAA on 24 kHz for the reference (in SpecLab sample rate detector) may work more or less on your side. All this can be tested by tracking the Alpha signal.
