Radio

A Radio is a communication device which facilitates global communication (over the entire server map). In order to receive a broadcast signal, both devices must be tuned to the same frequency (high, medium or low)

There are two types of radio available. The first, added in v.191, consists of a Spark Gap Transmitter and a Marconi Receiver. It operates by adding and removing the Daniell Cell on the transmitter, which in turn causes a bulb to turn on and off on the receiver. This makes it suited to Morse code.

The second type of radio, added in v.194, consists of an AM Transmitter, and AM Receiver. It allows normal speech-text and operates by speaking close-by to the powered transmitter.

=Radio Telegraph=

Spark Gap Transmitter
Add a Copper Ingot to a Copper Rod to get a spark terminal, then combine two of these, and add them to Boards. Choose the location wisely, as the transmitter can not be moved after this.

Marconi Receiver
Add a Coherer to Boards to start the Receiver. Choose the location wisely as it cannot be moved after this. Add Two Copper Coils, an Electromagnet then a Light Bulb to the receiver.

=AM Radio=

AM Transmitter
Add Charcoal to Copper Foil, and add another Copper Foil to make a carbon sandwich. Then add Copper Wire to make a Carbon Microphone. Add this to Boards to form the Transmitter base. Choose your location wisely, as the transmitter cannot be moved after this.

AM Receiver
Add Blank Paper to an Electromagnet to form a Loudspeaker, and add this to Boards. Choose your location wisely, as the transmitter cannot be moved after this.

=History=
 * v.191 - Spark Gap Transmitter and Marconi Receiver added.
 * v.194 - AM Transmitter and AM Receiver added.
 * v.247 - Can now remove antenna from Partial AM Transmitter, allowing it to be moved.
