Radio chatter
Go to the dls and locate kuid 45203:100759 for upcbchatter.
Go into surveyor and place it at a junction, yard, sidings, etc, etc. it shows up as a yellow and black box on your route and is sometimes hidden underneath the track which makes it difficult to remember where you put them at times. LOL
This is the only cb chatter sound I can find on the download station, I'm unsure if anybody has created something similar on another website.
