Youtube Ghost Hunters Channel?

So I remembe watching these 2 guys recording some supernatural activity and they posted a new video every thursday i believe. I dont remember their names but i know they are both 2 men, and i also dont remember their channel name, so if anyone knows what im talking about please tell me the name of the channel.

I remember seeing some videos where they used a recorder and a radio and they use it to ask ghosts some questions like: "Can we help you?" or "what happened?" "can you give us a sign that you are here with us?". Usually they get intellingent answers from them.

One of they episodes i remember very well, i think it was in a train railroad and a ghost kept ignoring them until those 2 guys asked him some questions like: "do you want us to leave?If you want us to leave can you give us a sign?" and the ghost did and some min after that the ghost started saying "Im gonna kill you" "leave me im evil" "Im evil" and they said "where are you?" and has a reply "behind you" and out of nowhere they felt like someone was blowing wind to their back.

So im sorry if i didnt explain well, but if anyone knows their channel please tell me. I completely forgot their channel name or their actual name. Thank you
