NCR Emergency Radio

The NCR emergency radio is an aid item in Fallout: New Vegas.

Characteristics
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.

Bugs

 * Calling for a supply drop in certain areas may lead to the cache not spawning at all, or spawning underground or in non-accessible areas, leading to never being able to get supply drops again. On the PC this can be resolved by using the command code.
 * Sometimes after dismissing a support Ranger, they can be found at Camp McCarran and talking to them will result in the Ranger joining your party again. It becomes impossible to dismiss them through the radio after this.
 * It has been found that for some users, the radio will never recharge after use and many aspects of the radio seem to function poorly. This is caused by the glitch that makes the NCR Ranger/trooper you called in respawn. To fix this glitch find and talk to the trooper/Ranger causing them to follow you. They can be found in the area where they died. This procedure will need to be repeated every several days.
 * If you have an NCR trooper or Ranger following you, they will be shot at by the securitrons guarding the gate to the Strip, as they most likely do not have clearance to enter. Note: this does not cause the Securitrons to be hostile towards you.
 * The Ranger or trooper may stop following you or just disappear when you enter a building.
 * Occasionally after a fight a Ranger may freeze in their position. They will not move until attacked but may freeze again the moment the danger has passed.
 * If you use items from the aid section fast enough you can "eat" your radio.
 * After the NCR Ranger dies, returning to the location several days later may turn up the same Ranger alive again, who will follow the player character again if spoken to.
 * Sometimes, when initiating the "Call of Supply Support" option, the drop will happen as usual. However, upon searching the drop, the container will have nothing inside it. You will still complete the quest and another NCR Ranger will give you another emergency radio.
 * Summoning the NCR trooper may only work once. After 24 hours, the option to call for the trooper will no longer be present. Even if you dismiss him within the 24 hour time-frame, the option to call the trooper will still not be there. The only way to work around this is to have him die while traveling with you, then the option will renew as normal. However, the glitch still remains so the only way to re-summon the trooper is to have him die each time. Also, if you summon the NCR Ranger after dismissing the trooper, it will only give you the option to dismiss the trooper, NOT the Ranger. This makes it impossible to dismiss the Ranger.
 * Having a trooper or Ranger following you and using the Big Mountain Transportalponder! can cause them to travel with you to the Big MT.
 * Sometimes when you call for Ranger support the Ranger will not appear.
 * Calling for support in the Mojave Outpost (to the east, close to the edge of the outpost) may result in either the trooper or Ranger dying.
 * If the player has a bad reputation with the Gun Runners and goes to the Gun Runners shop, the Ranger or trooper following becomes hostile and reputation with NCR is lost if the follower is killed, even if not by the player.
 * Sometimes when calling for support, the reputation with both the NCR and the Legion will reset to Neutral. They will still attack the player if they have done bad deeds for the faction.
 * When going through the strip gate with either Ranger or trooper will cause a continuous loop causing them to be killed by the gatekeepers.
 * If there are mountains nearby, the Ranger/trooper will often spawn inside the mountain, unable to get out.
 * The Boomers will bombard you and your NCR trooper or Ranger if you run through their artillery bombardment.
 * If the Ranger dies and you call in another one, the body will disappear and the new one will come in. This is likely because the Ranger that comes to you is always the same person so calling them in will just relocate and respawn them.
 * The summoned trooper/Ranger is not affected by the Animal Friend perk like normal companions and will be attacked if brought close to an animal.
 * It is possible to never receive the NCR Emergency Radio despite being idolized by the NCR. NOTE: Patching may resolve this bug. If this happens on the PS3, fast-traveling to the entrance of Vault 34 will cause the Ranger to spawn outside, although there are usually between four and five golden geckos outside the Vault, and they may kill the Ranger.
 * The Ranger who provides the radio may do it multiple times, sometimes one right after another.
 * When the player character returns to the spot where they received the radio, the Ranger who initially provided the radio might be standing at that point. If spoken to, he will repeat the previous dialogue but will not provide another radio. This can also happen when re-initiating dialogue with the Ranger after first receiving the radio.
 * With the Ranger or trooper following, one can go into Vault 3 and pass the speech check and neither the Fiends nor the NCR follower will attack each other until reaching the other Fiends in the back, but they still will not be hostile to the player character.
 * When initiating combat with the Ranger in tow, they will yelp "Whoa!" and sprint in the opposite direction and likely get killed by other enemies.
