Halo: Reach radio conversations

In Halo: Reach, there are UNSC radio conversations in most of the Multiplayer and Firefight maps. Some of the conversations are linked to each other to form a narrative. Transcripts are presented in the order of the areas in which the appear are visited in campaign.

Overlook
Radio is located on the top floor of the large two story building (in the 'Barn High' area) across from a pair of blue water drums.

Courtyard
Radio is located at the bottom of the ramp that leads out of Sword Base (area labeled 'Bend'), to the west side of the (blocked off) exit on a concrete ledge.

Waterfront
Radio is to the right of the gate at the end of the road (area labeled 'Road') that leads out of the pumping station.

Powerhouse
Radio is located on the kitchen counter of the dormitory (area is labeled 'Dormitory', natch). The dormitory is the single story building south of the gate.

Spire
Radio is located on a large concrete pad alongside the dirt trail labeled 'Mountain Road'.

Countdown
Radio is located in the south-east corner of the third floor (unsurprisingly, area is labeled 'Third Floor'), tucked behind a ridge of concrete near a fusion core.

Boardwalk
The Radio is located in the north-west corner of the map, bottom level (in the 'Courtyard' area), on a bench next to an overlook.

Beachhead
Radio is located in a room in the 'Pavilion' section that overlooks the south-west section of the map. It is near the spawn area and is the room that contains the missile launch control in the campaign.

Reflection
Radio is located at the south end of the map (area labeled 'Back Hall'), in the room with the vending machines.

Outpost
Radio is located in the small lookout building to the east of the AAA batteries. (In the area labeled 'Central Fire Zone'.)

Glacier
Radio is on the ground immediately to the right of the back door (and exit from the spawn point) as one exits from it. Note: the voices in this conversation is the same as Outpost.

Boneyard
Radio is located in the north-east corner of the map (area labeled 'Junkyard'), inside the temporary prefab building next to a rock wall.

Holdout
Radio is located on a table in the yellow building on the west side of the map (in the 'Field Office' area). (Building contains an ammo resupply crate, and has a small shed on the roof.)

Anchor 9
Radio is located on a table in the yellow building on the west side of the map (in the 'Weapons room' area). It involves an unnamed radioman giving orders to Delta-Romeo-two-three-zero and Charlie-Alpha-Alpha.

Breakpoint
Radio is located on the floor, next to the control panel near the window, in the Research Station.

Tempest
A radio conversation is supposedly found on this map. It is said to be found under the downed UNSC Longsword on the beach.

Trivia

 * To date, no radios have been found on the multiplayer maps Forge World, Zealot, and Sword Base. There is a radio in the 'Safe Room' area of the Firefight map Corvette, however there have been no reports of it picking up anything other than static.
 * The radio has the number '7.070.763' on its display.
 * In the Halo: Reach Multiplayer Beta, the Courtyard conversation could instead be heard on the map Overlook, from a radio in the structure where the Spartan team spawns.
 * The conversation about zombie plans on Holdout may be a reference to a similar conversation about zombie plans in Red vs. Blue. It also foreshadows The Flood.
