In case you don’t have any friends on the system yet, you can still test the system by yourself: just for fun, we have created the Echo Channel, a private channel with a special feature: normally you can’t hear yourself when you transmit; but with this special channel, anything you (or anyone else in your nearby vicinity) transmits will be repeated back over the air about 5 seconds later.

Like any other private channel, you will need a claim code to join it; for the echo channel, the claim code is the word “echo”! Go to the Channel List page, tap “Join”, and enter the 4 letters “e-c-h-o”.
