Most modern radios automatically set standard repeater offsets. The next column, Tone, indicates is if a PL tone is necessary. These tones are often referred to as PL tones, a Motorola Trademark, which stands for Private Line. This low frequency tone is indicated in Hertz. Tones listed in parentheses have tones listed but do not seem be required.
Some repeaters only turn on tone access at night.
The next column is the call sign of the repeater and the last column lists any notes I have about the repeater.
