Subject: | Garmin 430 and 530 connectors |
Not directly related, but similar...
There is a good article in this month's Aviation Consumer on that details
all the gotchas on the upgrade from a x00 to x00w.
The biggest issue appears to be the antenna and the type of coax you may
currently have installed.

Subject: AeroElectric-List: Garmin 430 and 530 connectors
Does anyone know if there is much difference in the wiring pinout and the
connectors to go from a Garmin 430 to a 530 ? The connectors look the same
but the P/N is one number off 4001 to 5001 etc. Could you just take the
connectors off the back plate of the 430 and make any necessary pin changes
and put the connectors back on the 530 back plate ?
Thanks,
Chad Feldpouch

Has anyone had the 430/530 WAAS conversion done and installed it?
We need to know if there were any modification needed to the plane's wiring
or antennas.

Subject: | Transponder noise |
After installing my radio stack (GNS 430, SL-40, GTX 330, GMA 340) and
firing it up for the first time, I find that I can hear the ticking
transponder broadcast signal in my headset (as well as on a AM/FM radio that
was turned on in the shop at the time).
I thought my com antennae may be to close to my transponder antenna, but I
can still hear the ticking broadcast even when the com radios are turned
off, and only the audio panel is left on. The ticking stops when the
transponder is placed in standby mode or turned off, so I know that is where
it is coming from.
Thanks for any ideas on how this can be cured?

Good Morning Eric,
It is almost a certainty that the antenna will need to be replaced and there
is a good possibility that the antenna lead will need to be replaced. There
is a minimum length required and that minimum length is longer than what has
been used for many installations. If your current installations uses RG-58,
it must be replaced regardless of length.
Other than that, no problem at all!
Happy Skies,

Here is some info concerning the 'WAAS' discussions: [thanks to Brent
Regan] Earl
Wide Area Augmentation System (WAAS) uses a series of strategically
placed ground stations that receive the GPS signal from the GPS
constellation, compare the reported position to the known position and
calculate the difference. This difference between the two is used to
infer the signal propagation delay through the ionosphere. The
ionosphere is very dynamic and not very predictable. The delay
"coefficients" are then transmitted to three (two currently in service)
specialized WAAS satellites that then transmit the correction data back
to earth. (simplified explanation).
"WAAS Compatibility" simply means that the GPS receiver can receive the
signals from the three WAAS satellites. Most GPS receiver can do this.
The trick comes in being able to process the WAAS data and use it to
correct your position information. There is a lot of math involved and
it must be done in real time so it requires a beefy Digital Signal
Processor (DSP).
Think of it this way, your telephone is "FAX Compatible" just like most
GPS receivers are "WAAS Compatible". You telephone can dial a FAX
number and receive the pops and screeches but it has no way to process
the data into a facsimile of a document.
WAAS Capable GPS receivers (like the FreeFlight) have an internal DSP in
addition to the receiver to make use of the WAAS data.
Do not confuse "WAAS Compatible" or "WAAS Enabled", the ability to
receive WAAS data (easy), with "WAAS Capable", the ability to receive
AND process the WAAS data (hard).
Caveat Emptor
Regards
Brent Regan

While your antagonist and victim have been identified, you
still need to identify the propagation mode. When presented
with your situation, we know that there is a combination
of three things that may eliminate the noise problem or at
least reduce it to unnoticeable levels.
(1) Fix some issue with the antagonist that doesn't
conform to industry practice for integrating
the product into an aircraft.
(2) Fix some issue with the victim that doesn't
conform to industry practice for integrating
the product into an aircraft.
(3) Eliminate or attenuate the propagation mode that
brings energy from the antagonist to vulnerable
components of the victim.
When anyone hears a short burst of "buzz" synchronous
with illumination of the transponder REPLY light, 90%
of the time it's an RF detection of the reply pulses
someplace in the audio stream. Obviously, our best
starting assumption is to set actions (1) and (2)
aside. Most of the time, the hardware we install has
been competently designed and tested to live in the
aircraft environment. So let's talk about (3).
What kind of audio panel? What are the connectors
on the back like? Is your airplane composite or
metal? Where is the transponder antenna mounted with
respect to the panel?

Subject: | Garmin GPS antenna. Cheap. |
List,
I just bought one of these puppies from Pac Avionics store, and works
perfectly with my G-296. For some reason it doesn't show on Garmin's website,
maybe
because at $29 it's too inexpensive. It has a small footprint of about 1.5"
sq. and 9 foot lead, BNC connector. Haven't seen any chatter on it so here it
is...

Bobby,
You may not have it yet, but I was wondering if the magnetic backing will
peal off easily. I wouldn't want any magnets in the airplane that are not
necessary. I suppose there are no mounting holes for screws but perhaps
double sided tape on the glair shield would work well.

I assume a remote GPS antenna will work fine on my RV7 located on top of the
glare shield but under the windshield. Is anybody operating with this
configuration successfully (Garmin 296 or 396)? If so, which antenna are
you using.

I use the antenna that came with my Garmin 296 car kit in the plane and
I use the extra one I bought off ebay when I travel in rental car. The
Garmin one in the plane is mounted on my glare sheild with velcro :-)
Goto this page http://webpages.charter.net/bobbyhester/MyFlyingRV7A.htm
and scroll to the bottom, them click the picture to enlarge.
I think the one off ebay with the magnet would work just fine here also.
It might mess with the compass, not sure.
