What type of digital signal is on 8983 and its x2 of 17966? It is not standard HFDL, although it looks similar. It has a pilot tone like HFDL, but the signal is slightly wider and usually a bit shorter in duration. It is repeated at 5 second intervals, with occasional added data making the signal a bit longer. It is a good signal on both freqs 24/7 in the Great Lakes area. The 17966 sits right next to the 17967 HFDL station from Al Muharraq Bahrain, but I can usually copy Bahrain in the local morning despite the interference.
