The range test with any v3.x modules is done with the antenna always ON. Only the very early 1.x/2.x modules (up to about 2007) did the range test with the antenna OFF. Look at the LED on the transmitter module when you turn on the transmitter. Once connected to the receiver the LED will flicker it is is a v3.x module. Otherwise the LED will be solid green.
