• freq — freq frequency in MHz. yes they said freq twice, i don't make the rules, i just report them 😭

💖 DESCRIPTION 💖

Return value: pointer to a channel detector on success, NULL otherwise. periodt.

the way this works: you either get back the channel detector that already exists for the frequency you asked about, or you get a freshly created one. either way you win, bestie 👑
