Radio Handset Communication Question!?

I have a radio handset. When I scan for channels, I find my friend's channel, but then I encounter a problem. When I push the button to speak and speak, he cannot hear me. The radius of my handset is 18km (my friend was about 20m from me when we tested it, so that cannot be the problem). My friend has a different make handset but also with the same number of channels and with the same radius. Do you have to have the same make handsets to be able to communicate? How do I sort this problem out?
 
Some radio handsets are sold in pairs where they put out an inaudible audio signal with the transmission. The receiver picks up the transmitted signal. But, unless the receiver picks up the particular frequency audio signal, it squelches the receiver, so that nothing is heard. When the correct audio tone is picked up by the receiver, the squelch is turned off and the transmitted signal can be heard.

This feature is called a continuous tone-coded squelch system (CTCSS). It allows multiple transmitter/receiver pairs to use the same frequency, without everyone having to listen to everyone else's conversations. You should be able to turn the CTCSS system off. But, it might not be just a switch on the outside of the unit. It might be something that only someone servicing the unit would know how to do (like some kind of setting or adjustment inside the unit).
