Walkie-talkies
A frequency is a meet
Short answer
Better than yelling. Still a tell if you chatter on a busy channel. Agree the number.
Also: radio · walkie
How it works
Radios need batteries and a matching frequency. Range is a rumour this page will not invent.
What to do
Set it at spawn. Check it. Stream-safe still applies — don't read stash codes on open freq.
Don't
Don't leave Kane on the wrong channel as a bit without telling him.
