## Description

Radio signs are design to allow players to communicate one another on a privately selected frequency or for better description, chat channel. The sign allows the player choose number frequency/channel/chat room from 0001 to 9999. The sign also allows any player on the vehicle it's attached to to communicate with anyone sharing this channel.

In other version of Navycraft, more advanced versions of later Navycraft Reloaded is used to link Guided Weapon. Radio used to link Advancedradar or Passivesonar signs with Mk3 Missiles to the Firecontrol signs. This is so the signs can control fired weapons to hit any target chosen.

### History

Radio is a early sign developed on Navycraft's original server, the first Naval Battlezone. At the time for that server chat was limited to the spawn. However, when outside this area, players are unable to chat with one another beyond roughly 50 blocks. Radio was necessary for players of allied or enemies to communicate with one another in chat style conversations.

However, over the years Naval Battlezone and following servers stop using the limited Global chat, thus radio was seldom used. However, the second Naval Battlezone, added additional functionality to Radio, by making it necessary equipment sign needed for Homing Missiles's high tech radars or sonars to work.
adars or sonars.

## How it Works

The player must click on the sign to change the numbers on the sign. This will change the number.

### Advancedradio or Passivesonar Functionality

Later versions of Navycraft Reloaded by March 2020, Radio required to enable either Advancedradar or Passivesonar+ActiveSonar work.

The following is steps of activating either AdvancedRadio or Passivesonar/ActiveSonar with the Radio sign after vehicle activation.

* Step 1 Activating Radio and change channel: Right click on sign, channel until first digit of the Radio is 2. Thus channel 2.0.0.0. Once done, Advancedradar or Passivesonar/activesonar will function.
* Step 2 Use Advancedradar/passivesonar+ActiveSonar : Once Radio is on channel 2000. Click on either sign to select target on screen.

## Notes

* Radio's changes - March 2020 will mark in change use of radio. Due decline use of radio due to globe chat not being limited to the spawn. Solmex, Navycraft Reloaded creator/programmer, changed the more advanced sensor signs to Radio sign. This would encourage use of radio and limit Advancedradar/passivesonar which controls Mk3 Missiles with Firecontrol to hit vehicles with accuracy.
