How do you make a radio transmitter on the Sims 2 Castaway?

by getting a transmitter and radio.

then you press make radio into a transmitter.

the transmitter and radio are both by the airplane in areoplane jungle, the transmitter is annoyingly hard to find as it is too small to see. The radio is big, however, and you should spot it right away.

also ig you do this try using the transmitter on the volano or in crystal caves...
