Hi Andy,
I will ask. My guess is that it was case size but I'll ask. I do
know that the next model is supposed to be 15%-20% smaller than the
current one. When they were telling me about it before, they did
emphasize that the actual transmit power did not go up. I didn't get
alot of details but I got the impression it had more about antenna
design to improve the actual efficiency for the transmit. I'll ask
again about that as well and see what I get back.

Later!

Mark,

Since you have contacts there I'd be interested to know why they
changed from 2xAA to 3xAAA cells. *Was case size the only
consideration, or perhaps the increased voltage increases the uplink
TX power? *In any event I'd far rather have the longer life of AA
cells than a smaller case size.
