I have an ICOM M-802 SSB and a Furuno FAX-30 (Weather Fax Reciever)
onboard
my boat. The ICOM M-802 has a dedicated receive port for DSC Receive.
Can
I share the FAX-30 Antenna with the DSC receive port of the SSB? if so
what
coupler should i use? (The SSB Xmit/Rec antenna is 3meters away)

They talk about a coupler in Section 7, but are not specific. As I dislike
t-connectors on principle, I would use a 50-ohm power divider. They
correspond to the action of a TV cable splitter but an actual TV cable
splitter would not perform well at HF and below You can build your own in a
metal project box, using a Y configuration with a 25-ohm carbon resistor in
each leg to maintain some semblance of impedance matching. Maybe you can
find an old TV cable splitter that you can gut for the purpose. For
receive-only, the antenna length is not critical. I recall Navtex specifies
a whip antenna of several meters; Navtex is on two freqs near 500 KHz, so
it's not far from the AM broadcast band. Hm-m-m ... What does a car radio
antenna look like???

Good luck.
