If a repeater owner say the dcs is 130.1 what and where how do you pit that in the radio?
A DCS would be 3 digits, no decimal point. DCS is digital and this is a digital code.
CTCSS, which is analog, is an audio frequency (254.1Hz or lower usually). Those will have an ##.#Hz or ###.#Hz frequency.
The DCS or CTCSS would go in the TRANSMIT side of the channel. The CTCSS or DCS is what gets heard by the repeater receiver and tells it that the traffic is supposed to be passed by the repeater. The repeater will usually require a CTCSS or DCS code to activate the repeater. Some repeaters can support more than one code.
Incorrect DCS or CTCSS codes will not allow audio to be passed by the repeater.
You would need to talk to the repeater owner to get the correct CTCSS or DCS code, or the repeater owner would need to publicly post that the repeater is "open" to users and post the DCS or CTCSS code publicly (like what you'll see on MYGMRS.com).
Always good practice to confirm with the repeater owner that it is OK to access THEIR repeater. Popping up on someone else's repeater without it being an "open" repeater or being given permission is not good form.
