All signals appear and disappear as I tune back and forth over a small spot Is this the autotuner doing this

Tuning back and forth over a small frequency range on 18Mhz  all signals appear and disappear.  I can hear a relay click as this happens.  I suspect the autotuner.  I am not transmitting, just receiving.
  The SWR over this range is about 3 to 1 and does not change much. See video

I wonder if this is a  LOW Pass filter clicking in???   I have a Icom R-8600 that acts this way at certain frequencies..  Not sure if the 6400 lets you switch them off or not???? Flex will know the answer.

It hapoens to me too. If you tune the band and hit the tune button when it ioccurs it won’t do it anymore

I'll give that shot when the sun comes up and there are signals to hear.  But I think I already tried that.   I report back.

Most likely is the tuner in auto memory mode
