Dual glide slope, $95...priceless!

The older VOR heads (the ones fed by the KX-170B style, not the KX-155

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.

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.
