Receiving Globe Wireless Channel Marker Idle Packets With Your Macintosh
Introduction
Globe Wireless is a provider of HF and satellite email and data services to the shipping
industry. Their signals are quite commonly heard on the HF bands,
as they have a global network of stations sending data around the clock on many different
frequencies.
Unfortunately, the protocol they use on HF is a proprietary one for which few decoders are
available. The signal uses at least two different modulations: 100 baud, 200Hz
shift synchronous FSK and PSK. MultiMode OSX is capable of displaying the transmitter ID in
the Globe Wireless channel marker idle signals.
Please visit

for full details on how this is done, by the person who determined the packet format.
