    @vk6akt

    Can you post a screen shot of your transmitter settings?

    We need to see your VFO frequency and your TX Bandwidth. Odds are your TX LPF is higher than 2800hz if your VFO frequency is set correctly for your country.

    In order to transmit on 60M, the TX requirements are very exacting and you are not allowed to exceed your TX specifications at all.

    Thank you AL K0VM ,you had the right answer the Tx antenna has to be on XTVR for 630m to transmit.
    I had not used my Flex 6400 for a few months and the firmware update had changed some settings.

    Sorry guys, my brain farted and I thought it was 60M. :)

    Yes, it has to be the XVTR port.
