You can use an S or SX for the transmitter, but the receiver definitely needs to be the S. The helicals in the S make the difference. I think the S has about 2-3 MHz of bandwidth on receive, while the SX has close to 20 MHz.
I have also used GE Phoenix S UHF radios for a repeater as well. Picked up a couple of narrowband units a while ago for $10 each. As longs as I keep the power down, seems to work pretty well. Any other questions, feel free to ask.
