Australian MHFCS net, a distinctive sign

Just a tip: in order to identify the MHFCS transmissions, in addition to the dial frequencies listed  here (remember that they use a 1500Hz offset above the indicated carrier) and to the shift and speed parameteres (tipically 600Bd/340Hz), think that these MSK signals exhibit a quite unique sign when inspecting the harmonics  using the SA 'involutions' tool. In this case, you will see the presence of several spectral lines in the 7^ power.
