 		<li class="rscadd">All radios now only work in their Z level. This means that the CommSat has a few more additions to work with this change. There is now a new Telecomms Machine called the Relay which allows information to travel across Z levels. It it then linked to a new machine called the Hub, which will receive information from the Relays and send it to the buses. Because every Z level needs these relays, which are linked up with Receivers/Broadcasters, every Z level will get one. There is one in the station, in the RD's office, one in Telecomms as always, one in the Ruskie station which is turned off and hidden from the HUB's linked list. The last one is in Mining but the location for it has not been decided yet.</li>
 		<li class="tweak">PDAs now need to be in a Z level with a functioning Relay/Comms Network in order to send messages. It will also send uncompressed (scrambled) messages like you would with the ordinary voice messages.</li>
