It seems like every time you turn around, you need GPS location input to make something
work.
First it was for moving map EFIS - OK - had a small hockey puck blu-tooth GPS receiver
- worked great.
Then ADSB comes along - need a WAAS GPS. Went the uAvionix SKYFYX-EXT/echoUAT route.
Was actually able to get the GPS info off of the WIFI the echoUAT setup.
Runs the adsb AND the Foreflight app running on the iPad.
Sweet.
This year I hope to finish the build on the Wittman Buttercup I have been building.
Because of where I fly, it will have adsb plus a new 406Mhz ELT - which is
supposed to have GPS position input!
Im not familiar with RS232 usage (thats used between the uAvionix GPS receiver
and the echoUAT) but it would be nice to share/use that data-stream instead of
adding yet another GPS receiver.
Is that possible? What about tapping into the WIFI GPS position data being generated
by the echoUAT?
I know, Im probably way out to lunch on this - but it seems there ought to be a
better way.
What say you?

Dave,
I am pretty sure that the ELTs all want GPS input via an RS-232 line, not
WiFi. (Except for the few ELTs that have internal GPS receivers.)
In my plane, I just spliced into the RS-232 line running from the GPS to
the transponder (GPS TX pin to the transponder RX pin). I ran that line to
the ELT RX pin.
As a computer guy, who always thought of RS-232 as bi-directional
communication, this seemed weird. I had to wrap my head around the notion
that RS-232 is being used to broadcast information (kind of like an FM
radio station) so it works just fine to hook one device's TX pin to the RX
pins on several devices.

As Art says, you should be able to send the position data from the
SkyFX-EXT to both the echo UAT and the ELT by splicing into the GY wire.
Check your ELT to make sure it will take NMEA protocol and 115200 baud
input.
Of course, the cheapest and easiest solution is not to have GPS position
going to your ELT. Seems silly to have that capability and not use it but
I've seen lots of installs done this way.

Interesting note on what Sebastien said.=C2- I didn't have a GPS signal
going to my ELT.=C2- When I had the off field landing, the ELT reported t
he last GPS location that it had received. . . about 40 miles from where I
was.=C2-

The "relatively" economical ACK E-04 accepts gps position and uses
aircraft power to keep the current position in memory and ready to
transmit it immediately upon activation. I'm amazed by how many owners
with that unit don't bother to run two wires from their "portable" gps
that sits on the panel and is plugged into aircraft panel anyway.
Waiting several minutes for a 406 elt to attempt to acquire a position
after activation is giving up a lot of the benefit of a 406 unit.

Thank you so much for the responses. I currently am not receiving
aero-electric posts for some reason but was able to read what you said
off of the forum web-site.
Thanks!

A follow-up:
Looks like Im back to square-1 as the ELTs I have looked into only handle RS232
max rates of 9600 - definitely slower than the 115200 rate from the SkyFX-EXT
GPS connected to the echoUAT. (that I wanted to use for adsb)
