maritime channels ?

All emissions on those channels are FM.

Thanks Dave, is it via some sort of data burst?

__._,
I need a LOTW verified QSO with a station in Hawaii via any valid digital mode
. This is all I need to accomplished the ARRL LOTW Triple Play award. Any
Hawaii stations on this list ?
I use a docking station that allows you to drop a SATA drive into it,
and it acts just like another hard drive on the system. it plugs into
the computer via a USB line, and has an external power supply to get
the +5 and +12 to spin the drive. This model of dock also has memory
card slots and 2
They are not normal FM transmissions. AIS uses an emission designator of
16K0FD. More specifically, a 9.6kbps GMSK FM modulation using HDLC packet
protocols.
Almost everything you need to know is right here:

Any public domain software that can decode it ?

Looks like AX.25 9600 packet by a different anme.
Anyone know if the G3RUH modem decodes it ?

Hi All...have tried to see if Shipplotter will run on Linux under Wine
have got the GUI up and it seems as if may be working ok.
havent got the hardware to fully try it out.

ANDE due for deployment from the Space Shuttle tomorrow will experiment with
the FX.25 protocol.
Based on the 1980's AX.25 standard the new FX.25 features forward error
correction.
