WRWJ727 Posted March 6, 2023 Report Posted March 6, 2023 I’ve noticed some repeaters show just one frequency of the CTCSS. Some show two for transmitting and receiving. If there is only one code, what would the other be? I’m new to this so here it goes… wouldn’t we need both a transmit and receive squelch code to interact with the repeater and people hearing me? Thanks. Quote

Thanks You never actually need the receive tone. Setting a receive tone only limits what you hear so with no tone set you hear everything on that channel. Setting a RX tone on repeaters that have both insures you will only hear an output of the repeater but you may be missing simplex on the same channel. WRWJ727 1 Quote
OffRoaderX Posted March 6, 2023 Report Posted March 6, 2023 Virtually all repeaters will have an input tone - that is the tone that you transmit to the repeater. The output tone which is the tone for receiving is optional. Some repeaters dont use one, even if they do, putting it on your radio is optional to help block-out other noise/traffic on the same channel. TL;DR - If it has just one tone/code, put it on the TX of your radio SteveShannon and WRWJ727 2 Quote
