Once you have installed the Blabbelon software and you’re registered, you can start to set yourself up. Start by setting up your hotkeys.
At the top of the middle panel, click on the Settings button. This will open a dialogue box that give you access to several settings.
Click on the button next to each of the hotkey selectors to set your desired keys. For example, a popular hotkey is the tilde key (~). The Officer Chat PTT allows you to set a separate keystroke to talk to only members of higher rank within a single blab room. You can again, select any key you prefer. For example, if you use the ~ key for talking to everyone, you might use SHIFT + ~ to talk to just the officers in the channel.
Lastly, there is an option to “Select Sound Card.” While most users will be able to rely on the defaults, if you use multiple sound inputs or outputs, you can specify which ones the Blabbelon Desktop App should use.
