Almost no antennas truly transmit on the one (and only one) frequency where they are resonant, yet they transmit well enough.
Although that’s an MFJ SWR meter and the numeric value might be incorrect, it still will show you where the SWR is the lowest, so I wouldn’t worry too much about that.
Like WSAM454, I absolutely would suspect that the frequency you are transmitting is the 462.xxx MHz frequency instead of the 467.xxx MHz frequency. I’m sure you set it right in software, but radios sometimes try to outthink us. Try using one of the factory repeater channels (23-30) with the correct CTCSS or DCS tone.
