Forrest,
As described below, not every station/repeater that requires a tone for access will transmit one back.
Sending a tone back to you is not required.
Reference to this can be found at http://www.miklor.com/COM/UV_CTCSS.php

Setting a channel Tone to TSQL Requires your radio to hear a tone from the other station or your receiver will not open to receive
it.
Always start with TX tone only. 

I hope this helps...

Curious why you say that using tone squelch on both TX and RX is not recommended???
