Norm,
I'll let you know after I talk to the tech at MFJ. He's out on vacation
until the end of next week. But I think it is a timing problem since the
TUNER light comes on but the tuner is not activated except when I transmit
say in FM mode.

I just purchased an IC-7000 along with an MFJ-929 auto tuner with Icom
cable and am not sure how this all works. I press the TUNER/CALL
button on the rig and 'Tuner' shows on the display but nothing more
happens. If I hold the button for 2 seconds or more that doesn't
change anything either. The 929 doesn't indicate the frequency and
there doesn't appear to be any output. However, on SSB if I talk into
the microphone the auto-tune features starts to work but takes a while
to get a good SWR because the power output varies with my voice. On
the other hand switching to CW or FM and keying the rig (CW) or the
mike (FM) it rapidly matches up and both the SWR and frequency are
displayed.
I had thought that when you push the TUNE button it would auto-tune
and I would be all set. I figured this is what you did when changing
frequency and just listening. But this isn't what happens and it
appears I have to transmit to get the auto-tune to work. Is my
understanding incorrect? Any help would be appreciated.

I have a similar problem with an MFJ-993 tuner. It worked as advertised
with a 706. Wouldn't tune when I went to a 706IIG, and doesn't work
with the current 7000 - same tuner, same cables. Works fine if I press
the tune button on the tuner. Went back and re-tried the 706, and it
still works correctly, but not the IIG or the 7000.
This is pure conjecture, but I think it's a timing problem - the 706IIG
and the 7000 don't hold the key line low quite long enough to start the
MFJ tune sequence. For now, I use the tuner 'tune' button. Some day
I'll get ambitious and put a 'scope on the key line and see what is
really happening.
