Thanks mshac, I've read the article and a few others (most through Sporty's iPad News), but I would like to see if XM has Gulf of Mexico specific satellite products like FF has. Of course, once out in the Gulf XM would provide the radar images along the coast, what I'm facing on the way back onshore.

I'm lucky with the ADS-B. There is an antenna overlooking my hangar ramp. I have everything on the ground before departure.

Attached is an image of Sirius's service and plan prices. I have Sirius for my vehicles, no breaks for the additional services.

They do broadcast satellite images, saw one of the Gulf.

As far as Radar (times do not include actual transmission times; antenna to processor, processor to repeater, repeater to aircraft)

• ADS-B:
  • Within 250 nm of aircraft
    • Transmits every 2½ minutes
    • Updated every 5 minutes
  • Over 250 nm
    • Low resolution
    • Updated every 15 minutes
  • Lighting
    • Cloud - Ground
• XM:
  • Transmits and updates every 2½ minutes
  • Lighting
    • Cloud - Cloud (developing activity)
    • Cloud - Ground (dissipating activity)
