Radio
Valid radio channels are 1 to 999999 Any other setting reverts to 1
Radio channels less than 1000 are local to the current war.
Radio channels 1000 to 999999 transmit across all wars including Parsec and Mega Wars. This allows a player to be in a Parsec war and listen to the team chat in a Mega War or of a planet is attacked.
Since the radio channels are public, teams should take care to rotate their channels on a regular basis.
