Click on the little wrench icon towards the upper right corner. This will bring up a new menu, go to Voice Settings, click Push To Talk. Click on the box on the right side, and press whatever key or mouse button you wish to be your push to talk.
This keeps you from having a constantly open mic, why is this good? one it prevents feedback for those of us that do not have a head set, but a boom mic and speakers. It also prevents rather potentially embarrassing moments from slipping through to your buddies. (not that I'm speaking from experience or anything on that last part...)
Hit Apply then OK to close the window. If you just hit apply this leaves the menu open for tweaking other items. Going to Audio settings will allow you to adjust your inbound volume levels, and out bound (inbound is what you hear, outbound is the mic) levels. For my setup I use a little less than half on each, but each mic, headset, or speakers, will be different.
If you ever want to change your settings on the fly without clicking the wrench icon you can do so simply by adjusting the sliders on the right side of the screen the speaker icon naturally is the inbound, the lil mic is the out bound. You will also no doubt notice there's a chat window here as well, so you can link things amongst yourselves, without having to resort to ye old CTRL C and then CTRL V like you would in game. Or chat, if there's more relevant to the match conversation going on in the voice channel.
The program also has it's own PM system so you can check messages given to you by your buddies if they aren't on when you are, etc.
The contacts Tab, is where you add people to your RC friends list. It's also where you can ignore problematic players if you are in other channels you don't own.
The Groups Tab, is where you can search for new groups, recommended groups, as well as get access to an Events and contests calendar.
You can also Favorite channels you frequent often to keep them on an easy to find list. Simply click the little star on the upper left side.
If you are playing a game that supports the in game channel feature, you do not have to do anything fancy, RC automatically makes itself discreetly present. You can also move it's location around on the screen, or simply close out the little window entirely.
The other settings and options are pretty straight forward as well.
i thought star trek online had a built in voice chat program?
If you can call that a voice chat program.. sure it does. It only works like 40 percent of the time, has horrible voice quality, lag issues, screws up your chat channels, and can cause a massive memory leak that will crash out your game and anything else that happens to be running at the time.
It also suffers from an uncustomizable push to talk key (N... seriously it's N think about how fail that is for where your hands sit while gaming) as well. Oh it also doesn't have a hot link capable chat program built in, no dedicated friends list so you can find your buddies when they aren't playing sto...
