NCR Emergency Radio

The NCR Emergency Radio is an aid item $$

Gameplay
In the Aid tab of the Pip-Boy, the NCR emergency radio can be selected. Afterward, the Courier will have the option to:
 * Call for NCR supply support.
 * Call for NCR Trooper support.
 * Call for NCR ranger support.
 * Cancel (no support).

The radio can be used every twenty-four hours.

Supply support
Calling for supplies starts the quest Emergency Radio, which drops an NCR supply crate with random ammunition, and/or armor in the near vicinity. Sometimes an NCR ranger will run to the player character after completion, and go through the same dialogue as when they first received the radio, but no additional radio will be provided.

Calling for trooper support
Calling for trooper support summons an unnamed NCR Trooper to the location. The trooper cannot be controlled by the companion wheel, but will follow the player character as a companion and will still be present after fast-traveling. The trooper is always equipped with NCR armor and a Service Rifle. He or she has 50 Hit Points and a Guns skill of 46. The support can be dismissed via the radio.

Calling for NCR Ranger support
This causes an unnamed NCR Ranger to the location. The ranger works similarly to the trooper but will have better gear and stats. He or she is equipped with NCR Ranger Patrol Armor and a Cowboy Repeater, has 220 Hit Points and has Guns and Unarmed skills of 100 each. The ranger also carries $50 NCR. Like the trooper, the ranger can be dismissed via the radio.

Location
The Courier will receive the emergency radio from an approaching unnamed NCR ranger when their Reputation with the NCR reaches "Accepted." This can happen any time during the game once the minimum reputation requirement is met. The item cannot be dropped since it is considered a quest item.
