This looks useful. So the problem has to do with receiving rather than
trasmitting then?

If I have a frequency tuned (say an ATIS) but am not in range enough to
break the squelch, will I still experience the problem? Is it simply
the act of tuning the frequency, or the act of actually _receiving_
something on the frequency?

Is anyone else having major GPS satellite reception problems with their
396? I've made two trips since getting the 396 and have noticed the
following...

After takeoff or on arrival within 5 miles of airports here in the
Phoenix Metro area I have _always_ experienced a loss of GPS signal.
This could happen even on a smooth, straight in approach (it's not that
I'm turning away from the satellites, etc.)

According to this page (Jay Honeck had recently shared the URL elsewhere)
http://www.scn.org/~bk269/gps.html , certain nav/com frequencies can
prevent your handheld GPS from receiving signal.

It's likely, since it's in the same area, that you're tuning one of the
frequencies listed on that page.

I've always found that changing frequencies solved the problem; put up
your satellite status page, then get permission from ATC to go off
frequency. Turn OFF the radios (if you're in VFR and not using the NAV),
and you'll quickly know whether you've got a nav/com interference problem.

I first found this problem when I bought my Arrow (Narco panel), and had
this problem within the first day or two. I have had interference affect
my GPS Pilot III, 196, and 396.
