It equal power across the band, which wind program noise I the form of the filter response.
My favorite one that almost always gets an response is: 'Mark to Kelly, consist of Kelly. Ksh. over.' The 'ksh' should preferably emulate the static sound of a two way radio, like her my partner and i are regarding the battlefield. Girls love this one, usual like a 95% effectiveness when used for the primary text.

Kids love battles.
