NOTE: With the exception of channels 5 and 35 (emergency channels), the repeater output and input channels can legally be used for “General use” outside of the coverage area of a repeater on that channel. However, under the right atmospheric conditions a UHF signal can travel hundreds of kilometres, reaching a repeater that you might not be able to hear. It is for this reason we recommend you avoid using channels 31 to 38 and 71 to 78 for normal conversations to help ensure you will not cause interference to some distant repeater you never knew existed!
