GPS loss of signal explanation

I think its usually a software problem. I've had various issues with
losing signal in different scenarios with my Garmin handhelds and
Garmin has always provided me a ROM update which appears to address the
issue.

This is an interesting site that explains why some pilots (seemingly
mostly running Garmin-brand portable GPS units) are having trouble with
losing satellite lock.

So far I've not had any trouble with our new 496 (and I've never had
any trouble with the Lowrance or AvMap units) -- but it's nice to find
an actual explanation for a problem that has struck several folks on
this group.

I have a full Narco stack in my Cherokee and keep the antennae for my Garmin
196 just to the left side of the windshield brace. I've never have seen a
problem with the GPS in the past 5 years.

This spring I upgraded the radios to the 12D+ package with the same results.

LOL! For the Narcos or the Cherokee -- or both...
That was cruel, I'll take it back. Hehehehe....

I don't know why...I've never had a lick of trouble out of any of it.

Atlas has two Narco coms, a Narco DME, and two Narco GS/VORs. All work
perfectly, all the time.

I've not quite figured out where the anti-Narco sentiment come from,
but it's almost as insidious as the anti-Microsoft attitudes out there.

They probably are good radios. The bad rap against them came because
they were the first to introduce the concept of "non-field serviceable
units". They took away the right for avionics shops to work on them,
requiring they all be returned to the factory (at a price they set).
However, today we have Garmin doing the same. Compare that to a King
radio where any just-out-of-school avionics guy can do a field strip in
an hour.

Perhaps 'cause they are just old, without the new bells and whistles?

Jay,

It came from avionics shops that got pretty ****ed at Narco when Narco
decided to pull all service into the factory. Narco's reasons for doing
it are understandable, and I think make sense, but the avionics shops
have never forgiven them for taking away a good chunk of their repair
business.

I've had several $300 Narco auto-dimming EL displays fail. According to
some very reputable local avionics businesses, Narco isn't easy to deal
with.
