The News Office in the upper-left corner of the station, between the head of staff teleporter and the public podbay, is the ship's local radio station, competing with the usual debris-field radio station. You can easily recognize it by the nice blue floor, covered with beige carpeting and a great big table covered with radio equipment.
There's a few rooms off to the side; a small bedroom-office to the left, and a breakroom to the north. No expense was spared to fully replicate the radiolab in space.
The main purpose of this place is VERY noticeable, and it's putting on a radio show. To this end, this place is outfitted with a bunch of radio equipment, most of which is explained here. As ever, anyone can be a radio host, so you never really know who might be putting their voice into the airwaves. Some mystic immersed in the secrets of the Solarium? A sensefreak who's taken--and is possibly currently on--every known drug in the universe? An insane show host who offers great prizes for those who press their head and luck on the Russian revolver? Who knows?
There is no vent. Vents are old news.
The APC for all the rooms is on the northernmost wall.
