Dual glide slope, $95...priceless!

The one that was off is a newer Garmin, installed along with the GNS430
by the previous owner. While I haven't checked the logs on this, I'd
bet it hasn't been tuned since then. During the first 1.5 years of
ownership, both VORs were never more than +/- one degree.

Although technically an avionics shop needs to do the adjustment most
owners puchase the spline screwdriver and do the adjustment themselves.
You simply remove the OBS knob (via set screw) and there adjustment
screw is behind it. Usually I do it as MHR or SAC where you have a VOT.

Hmmm, interesting...not something that gets logged I'd bet :-)

Jack, you are going to be in the position of the guy with two wris****ches.
He's never sure exactly what time it is.

Yes, and that setscrew is a SPLINE, and a little tiny bugger at that. It
takes the smallest spline in my toolbox to get it off. The screwdriver
needs to be a small long shaft as well...I've got an old footlong
eighth-inch fiberglass "TV Tuner adjuster" that works for me.

Log? You keep a LOG?????

LOL..."Ok we're above glide slope, no below glide slope, left of course,
on course...aw heck, average everything out between the two glide slopes
and localizers"

Sounds like I need to get me one of those...um...for...er...when I need
to tune my TV :-)

Well, yeah, gotta have some place to put those expensive stickers the
shops type up for us...on those occasions where we opt to have them work
on the plane that is :-)

Interesting, those are normally highly accurate. I also have two
glideslopes. I always tell myself I should set both but almost always
forget. Even when I do set it, I tend to forget to look at the #2.
However, I do take careful note of the FAF altitude as a GS
verification.
