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. _____ From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of CHAD Sent: Tuesday, March 06, 2007 11:30 PM 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 ?

ERic-- RV-10, 40014 N104EP ________________________________ Message 4 _____________________________________ Time: 05:40:29 AM PST US From: "Dustin Paulson" Subject: AeroElectric-List: 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? ________________________________ Message 5 _____________________________________ Time: 06:18:44 AM PST US From: BobsV35B@aol.com Subject: Re: AeroElectric-List: Garmin 430/530 and WAAS 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!

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).

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?

Cheap. 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 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.

I think the one off ebay with the magnet would work just fine here also. It might mess with the compass, not sure.
