I'm a merchant sailor turned computer science researcher who happens to be a ham as well... Hence the following 'might' make some sense ;-)
I want to have a go at decoding a transmission mode called Gaussian Minimised Shift Keying (GMSK). This is the mode used by shipboard UAIS (Universal Automated Information System) transponders. For information on UIAS see
http://www.ais.org.
I'm not aware of any software that can decode GMSK transmissions. If there is, I'd love to hear about it! Alternatively, I'm looking for technical information about how to program a soundcard, preferrably under Linux. I'm apathetic about programming language, any will do.
Thanks!
