RE: Comms to FeniHi Spraypilot,
Thats funny with ur Iridium not working well. I've had mine in the jungles of Northern Panama and am presently using it in the Chagoes Archaipelago deep in the Indian ocean. Have even used it in Iceland a few times and in the steeps of far eastern Turkey (near Van).
I've had a few times where I couldn't connect right away but could connect after a try or two. Are you using the antenna that comes with it or a passive extension antenna or one of their active antennas?
