It would seem that UPS-AT technology is significantly better than Garmin's.

I can't speak for the GNS 430, but the SL30 has UNBELIEVEABLE signal
processing capability. I can track a good VOR well over 100 miles, and
I've got a mediocre cats whisker antenna mounted on my tail. I'm told
the SL30 uses digital signal processing; I don't know what the GNS 430 uses.

In short, I'm not at all surprised by your experience.

Hi!

I have a SL30 and a GNS 430 in my plane. They use the same antenna via
a splitter.
When I dial in the same VOR in both units the SL30 catches up the
radials always between 20 and 50 nautical miles earlier than the GNS
430! (Altitude about 3000 ft, flat area)

Is this normal?
What is your experience?
How far away do you have a reception of a VOR with your GNS 430?

Fly safe!
