ok so i finally passed my tech exam last month and ive been listening to the local 2m repeater for a few weeks now trying to get a feel for it before i jump in. i understand the basic concept of the offset and all that but im confused about the CTCSS tone thing. like i programmed what i thought was right into my baofeng but sometimes it sounds like im hearing people fine but when i key up nobody responds and im not sure if its because my tone is wrong or im just doing something wrong with timing or what.

also i noticed sometimes people just start talking after a kerchunk and sometimes they wait for a specific beep or something. is there like a standard way people are supposed to do this or does every repeater have its own rules? i dont want to be that guy who does something annoying without knowing it.

Welcome to the hobby, and good on you for listening first before jumping in -- that already puts you ahead of a lot of new folks honestly.

So the CTCSS thing: the tone you set to transmit needs to match what the repeater expects to hear before it opens up. If you've got the wrong tone programmed (or none at all) the repeater just ignores you. Most repeater directories like RepeaterBook will list the required tone. Some repeaters also have a tone squelch on the output side, meaning you wont hear anything unless you also program a receive tone, but that's a separate setting -- a lot of people just leave the receive tone off so they hear everything.

As for timing, after someone finishes talking there's usually a courtesy beep -- that little chirp or beep from the repeater means it's reset and ready for the next person. You want to wait for that before you key up, otherwise you'll step on the tail of someone's transmission and cut off the last bit of what they said. It's one of those things you pick up fast once you start participating. Just jump in, say your callsign and that you're new, most folks on local repeaters are pretty welcoming.

yeah the tone thing got me too when i started out. one thing i'll add is that some repeaters dont require a tone at all to access them, they're open. so if you're not getting through even with a tone try transmitting without one and see what happens. also baofengs can be a little weird with how the menu labels CTCSS vs DCS, make sure you're setting the actual CTCSS and not accidentally set it to DCS or something. i wasted like a weekend on that before someone pointed it out to me lol
