[aprssig] Deluo GPS Lite altitude limit

I hooked the thing up to my bench supply and multimeter and let it run for a
few minutes.  At 5 volts, it jumped around quite a bit between 45 and 85 ma.
Can't say if it got a fix or not - the bench is pretty far from the window
and I couldn't get it where it had a clear view.  It's entirely possible
that the power consumption drops when it's locked and tracking.

Even at an average of 60 ma, that's still just half what the other units
draw.  Not too shabby.  And it fits perfectly in one of the elastic bands on
the shoulder strap of my CMC Rescue comm harness.

Further on this device, the specs say:

Power supply :
   Power consumption:
   +5.0VDC and up to 9.0V DC
   Typical (tracking): 120mW


They say 120mW which would be only  24mA!    Can this be possbile.   I
noticed in the feature grid comparing all  three of Deluo's offerings
that the other two were 120-160 mA. I wonder if this spec is a type and
that they really mean 120mA,  not 120mW......
