Do you have to use codes to use an open repeater? The tones for WQYS795 in Tarboro NC show "input and output tones are 67.0 Hz" and it is an open system. My MXT275 has a CTCSS code 1 for 67.09 Hz. Are these the same thing? And like I said, my gmrs has 67.09 but not 67.0, don't know if that matters on analog? Anyway, I haven't been able to make contact verification.
