I just finished an experiment and found out that it is possible to chain repeaters to get an insanely massive range. The thing is that the messages on the initial radio beacons need to be reset each time a repeater is added. The way around this is just to put the message on the radio beacon after all of the repeaters in a network have been built. Also, once you are locked on to a signal that has passed through a repeater, the compass will point to the nearest repeater rather than the source of the signal. When the compass displays the information about the available signals, it will show the distance to the nearest repeater along with the total distance relayed.
