Wow! Quite a response. Sfax, the db test is most interesting (and I will try it for fun) but looking at the bars is enough for me. I rest the phone on the cradle without snapping it in and look at the reading (bars on the phone). I snap it in and wait 10 seconds for resampling and see if there is a change, and there is none. I then move the car because there is always the possibility that the roof antenna is in a "dead spot" and moving would eliminate the variable.
I was once an active mobile ham radio operator before cell phones and had experience with vhf and uhf signals with both internal and external (roof & trunk) antennas and the external will always win even with the loss in the coax, which could be substantial at cell phone frequencies.
Just another conjecture - the signal didn't change either up or down. This suggests that it may never had really connected in the first place. The X3 brochure promotes the increased range as a benefit. Still not sure why it doesn't work as advertised. Even an increase from one or two bars to three bars will go a long way to get you a handoff to the next tower, reducing dropped calls. I'm pursuing this through my dealer as well. If I learn anything, I will post it here. THANKS all for your suggestions. - Andy
