F 6700+PG+TG on 6m- high SWR on radio's output


Recently I fired up my setup on 6m band and note SWR about 2.7 on Flex 6700 output. Everything is fine on other bands. F 6700 ATU is always bypassed when using PG and TG.

Any suggestions where look for a problem?

    Do you have a dummy load to test?

    Start with it on output of 6700.

    Next on output of PG XL.

    Then output of tuner with tuner in bypass, then in circuit and tune.

    Try to narrow down where the problem is. Maybe a bad or loose coax jumper.
