Help with F-18 radio setup

[killerquagmire]

Hey guys, I can't seem to get comms 2 working with vaicom. I have comm1 setup with TX1 and comm 2 with TX3. No problems with comm1 but when ever I press tx3 for comm-2, I get the little triangle indicating activation but I get no squelch, no response. All the activation settings in voice attack for tx1 and tx3 are identical. 

Not sure what I'm doing wrong here. Any tips?

You need to use TX2 for comm2.
