A local group here has "experimented" with mixing 103.5 and 123.0 for a number of years to "alert" on some things that happen on a particular repeater. It's completely up to the receiver as to whether or not it works. Typically the more "modern" the receiver, the less chance it has of working properly. In your case, it sounds like you're trying to link to IRLP, perhaps? It's probably better to just switch the whole repeater to CTCSS-follows-user when IRLP is active, and back the other way if you want when not. (We just left ours in CTCSS-follows-User, even though we originally planned to switch it back and forth with DTMF from the IRLP node. Once in a while I punch in the "normal" mode out of boredom... just to play with it. The IRLP still always sends the command to switch "just in case" so it doesn't matter what mode it gets left in.)
