After struggling with my EchoFlight Orbcom datalink, I gave up. Forty minute
nexrad data, when it worked at all, didn't help me much. Lo and behold, they
now have a Wxworx interface, which I just installed today. Within two
minutes I have all the weather data in the entire U.S. in high-res detail.
The oldest nexrad image is 5 minutes and usually it's two minutes old or
less. Awesome. Awesome! Cockpit weather has finally arrived. The EchoFlight
(now called TrueFlight) also has all my plates, approach overlay, landsat
imagery overlay, and on and on.
