Cheeck the OMI manual. Has a standard TT blurb on how they handle high SWR.

Subject: [TenTec] AL 811 High Input SWR with OMNI V
> I bought an Ameritron AL811 Amp and hooked it up to my OMNI V.
> On 10 meters the OMNI V meter on reflected power reads a little under 3 to
1
> when I tune the amp using either the tune or a pulser.
> My antenna SWR is flat and the problem seems to be from radio to amp.
> When I go to SSB the meter on the OMNI V set to reflected reads flat.
> I can whistle into the mike and get full output from the amp and the input
> SWR remains flat on SSB.
> When the problem takes place on CW or Tune I still get full output from
the
> amp but high input SWR.
> IC shows under 20 amps even at high SWR on CW.
> Questions:
> Why only in CW?
> Could it be the meter on the OMNI V getting RF?
> Has anyone had this experience?
> What is causing this problem?
> Does the OMNI V automatically fold back output as some of the other brands
or
> will it keep pumping out power even at high SWR causing damage to the
finals?
> Thanks in advance.
