Setting up an Untuned Microphone

An untuned microphone is an inventory item, but it currently has no artwork. Dropping it can be problematic. You will only see a pink box, which may flicker and be difficult to click on to pick it back up. Try clicking on your avatar, Utility, Temporarily make nearby portables look like bags.
With the untuned microphone in your inventory, click on your avatar, Special, Tune a Microphone
Pop-up window: Name of station? This is what players will type in to join the channel.
The microphone is automatically dropped where you are standing. You can pick it back up and drop it elsewhere if the spot isn't to your liking.
