See other SPOT threads, but as I understand it, the SPOT does transmit
once a minute already. It is a "blind" transmission, so there's no
acknowledgment from the satellite. So in live tracking, it transmits
the same message 10 times, then updates the coordinates, and repeats.
An OK is also transmitted repeatedly, that's why both LEDs will flash
for 15-20 minutes after pressing OK.
Again, this is all part of the design, which is targeted at the hiking
market. An aviation unit might also include an altitude.
