Not too sure if the same applies for the Diamond, but try em out and see.
EDIT: Ok so apparently, according to the first post, a radio flash on a diamond does erase your memory. I can not confirm this since I have a TP and not a diamond, but back your info up anyways just to be safe.
any clue on which is better on the West Coast? Cali to be exact? cause my reception inside my house is garbage... but outside it's clean...
