NCR Emergency Radio

The NCR Emergency Radio is a miscellaneous item in Fallout: New Vegas.

Location
You receive this from an unnamed NCR Ranger at a random location when your Reputation with the NCR becomes Accepted or higher. If you are disliked in anyway by the NCR you cannot receive this item.

Characteristics
In the Aid tab of your Pip-Boy 3000 you may select the NCR Emergency Radio. You will see a menu with options to: Call for NCR Supply Support, Call for NCR Trooper Support, Call for NCR Ranger Support, or Cancel [No Support]. This option is only available in certain NCR approved areas.

Calling for Supply Support
Starts the quest Emergency Radio, and drop an NCR Supply Crate with random ammo, and/or armor. Sometimes an NCR Ranger will run to you after completion, and go through the same dialogue as when you received the radio. Note: You will not be given an additional Radio.

Calling for Trooper Support
Causes an unnamed NCR Trooper to run to your location. They cannot be controlled by the companion wheel but they will follow you until their death and fight hostiles. They will follow you while fast traveling. The Trooper is always equipped with NCR Trooper Armor and a Service Rifle. He has 50 Hit Points and a guns skill of 46.

Calling for NCR Ranger Support
Causes an unnamed NCR Ranger to run to your location. They cannot be controlled by the companion wheel but they will follow you until their death and fight hostiles. They will follow you while fast traveling. The Ranger will always be equipped with NCR Ranger Patrol Armor and a Cowboy Repeater. He has 220 Hit Points and a guns and unarmed skill of 100.

Both the NCR Trooper and NCR Ranger can be dismissed by simply selecting the radio again, and then selecting Dismiss.

The radio can be used every 24 hours. A message saying 'Your follower has died!" will appear when the Ranger or Trooper is killed. Your Ranger may be killed by the Securitrons guarding the gate leading into The Strip. If at all possible, use the Monorail to gain access to New Vegas.

If you lose your reputation with the NCR, you will no longer be able to call in support until you once again raise your reputation.

Bugs

 * 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.
 * 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 respawning. To fix this glitch find and talk to the Trooper/Ranger causing them to follow you. They can be found at the area were they died. This procedure will need to be repeated every several days.
 * 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 'CompleteQuest 0015FB7C'.
 * 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.
 * Some times when you call for Ranger support the Ranger will not appear.
 * 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 he/she has done bad deeds for the faction.
 * Player may lose all reputation with the NCR when having a Trooper following and doing certain missions such as Booted.
 * If you have two companions with you and use the radio, the NCR Ranger sometimes gets wedged in a door when going inside. Going back through will fix it.
 * After the NCR Ranger dies, returning to the location several days later, the player can find that the Ranger is alive again, and upon speaking to her, she will follow the player again.
 * When going through the strip gate with either Ranger or Trooper will cause a continuous loop causing them to be killed by the gatekeepers(very convenient with jury rigging as it provides an unlimited supply of service rifles and cowboy repeaters
 * 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.
 * There is an infinite exp glitch where if you call for NCR Ranger support and shoot them before they can reach you, your companions will kill the Ranger who will then repeatedly spawn. You get 50xp for every kill and this does not cause reputation loss with the NCR or negative karma. Doing this may cause your game to freeze.
 * 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 them and respawn them.
 * The summoned Trooper/Ranger is not affected by the Animal Friend perk like normal companions so bringing them close to animals will allow you to obtain infinite amounts of whatever they're holding. Of course this not the case if they manage to kill them all. It is suggested to enter an area with incredibly strong animals or just medium level animals and pick-pocket their ammo. It also helps for them to be in packs.
 * 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. 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.
 * 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 is possible to never receive the NCR Emergency Radio even if you are Idolized by the NCR. NOTE: Patching may resolve this bug (Confirmed after doing so, three previous play-troughs prior were I did not receive radio).
