Are the station IDs for the GMDSS DSC stations on HF (2187.5, 4207.5, 6312.0, etc.) the same as the IDs used on longwave DGPS stations? I've been monitoring digital signals for decades, but recently discovered I'd missed the easy-to-log HF GMDSS signals - so I fired up DSCDecoder, and I'm seeing short "health" messages with Station IDs, but one of the IDs seem to be from an Asian station, which is unlikely given propagation at the time. Any advice regarding this mode is appreciated! 73 de KC2KLC
