Tony,
I don’t know but I am building a Legacy and plan on dual
GRT Horizon HX with the dual AHRS and would be very interested in what you
learn.

Subject: [LML] GRT Horizon HX Ahars issues
Hello
All,
I have the GRT Horizon HX dual Ahars in my Legacy. For the first 30 hours
i had absolutely no problems with these units. After that first 30 hours
i took it in for paint and interior and added the second alternator as well as
the canopy seal system. Since then i continually lose ahars #1 within the
first five minutes of engine start, and lose ahars#2 within the first
hour. We have done a lot of trouble shooting to look for loose ground
and/or power. The other interesting thing to note is that if turn on the
system on the ground without the engine running, I never lose the ahars.
I do have a Vertical Power Vp-200. I see no voltage or current alarms in
the VP-200.
GRT folks seem to think that there might be an interference with the ahars if
COAX is close by. Has anybody experienced anything like this?
