Any future possibility that the ex600 might use the garmin 69 unit?  I see avidyne isn't making the mlb700 anymore... what is the thinking here?

sigh. I've got the WSI on the MLB700. have a GDL-69 in another bird with XM. NO COMPARISON.  I'll take WSI everytime when convective activity is a flight factor.  WSI is base radar while XM is composite. What is Avidyne thinking here?

Was there ever an answer to the EX600 with Garmin 69 unit.  When I purchased mine this was in my spec and I was led to believe it would be in a near term release.  I do also have an MLB100 with weather that is currently displaying on my IDF540.  I could swap the XM vs the MLB data if either works on the EX600.

I guess Avidyne must have seen this coming. I sure didn't. WSI is the game changer in in-flight weather.  When they dropped support for the MLB700 it didn't make sense. I guess market factors lead to it's demise. Here's the excerpt  from the WSI letter to subscribers I received today:

 With this letter, The Weather Company will be exiting the market for certified aircraft hardware for delivery of our industry-leading solutions in the cockpit. We will instead rely on our partners, such as SXM, to work with aviation industry manufacturers to provide solutions that deliver our products directly to cockpit displays. 

If you have any questions about this announcement or require clarification, please contact your sales representative. Thank you again for your support of the WSI InFlight product line.

They are going to honor our existing contracts through the end of the year. sigh. k

So to understand this correctly, the MLB700 will be a useless brick by the end of this year????

AviSimpson, can you please advise on the MLB700? This is still a very useful device especially  for weather outside the lower 48 give the coverage of Sirius.

This isn't a MLB700 issue. This is an issue of WSI, the weather services provider, dropping the subscription service at the end of 2017. While the MLB700 can still function, it would be useless if your goal is to receive weather products. Since we didn't have any advanced warning of this, we are still working through the options for our customers.

OK, thank you, so work in progress, standing by..... Should I cancel an ongoing install of an MLB700 as part of a major avionics upgrade in one of my planes or go ahead with it? This is the 3rd install for my aircraft... And what happens with the MLX770 weather product? Is this also affected?

I'll leave that decision up to you. The EX600 also supports the XM DO76 which isn't affected by this cancellation. So if you can find one of those, it's probably the better bet. The US weather services for the MLX770 will be discontinued.

Great. So here go many thousand $$$$ in value. And we wonder why aviation is less and less attractive. When Loran was replaced with GPS, there was much more transition time and WARNING. I really do hope you guys come up with a palpable exchange of the MLB700 for some ADS-B solution, so we don't lose the weather at least for domestic. And that means now that north and south of the border the weather options have significantly suffered, as the Sirius footprint was much better than the XM..... (Aside of my preference for WSI weather)
Concerning the MLX770, it would be quite easy to do something like the sailors have on much lower cost solutions, i.e. GRIB data, like this: http://www.ocens.com/WeatherNet-4-P514.aspx

So one more question: The Heads Up XM receiver works only with the EX600 or also with the EX5000 (which I have in my twin with the ART2100 radar)? and, the ADS-B solution is being prepared only for the EX600 or also the EX5000?

Thank You.

The XM receiver is supported on EX500/600 and 5000. The software update for the EX500/600 and 5000, currently in development, supports our SkyTrax series of ADS-B receivers.

AviSimpson, Was just thinking, with XM & Sirius now one company, does Avidyne not have enough clout to make them replace WSI weather on the Sirius Satellite with XM, so we can keep the MLB700 and the superior outside ConUS coverage of the Sirius footprint? (And save each of us MLB700 users a good $3000 which it would cost to get the Heads-Up receiver installed instead of the MLB700, with inferior coverage?)

I may be mistaken... but it was my understanding that the "Sirius" signal (vs "XM" signal) are quite different... Sirius uses a chain of low-earth-orbit satellites that are constantly moving in and out of LoS... XM uses a geostationary satellite.  I am guessing that both signals (and signal handling... esp the LoS transitions...) are quite different.

Sirius broadcasts from three satellites, which were launched in 2000 from the Baikonur Cosmodrome in the Republic of Kazakhstan. The satellites orbit the Earth in an elliptical constellation, between 15,200 and 29,280 miles above the Earth's surface.

The three solar-powered satellites follow one after the other, so when one passes out of the Northern Hemisphere, for example, another is right behind it to provide uninterrupted transmission. Two ground stations, one in Ecuador and another in Panama, are in constant contact with the satellites.

XM has two Boeing Satellite Systems International satellites that transmit its signal. The satellites are called Rhythm (XM-3), which launched on Feb. 28, 2005, and Blues (XM-4), launched on Oct. 30, 2006. These two satellites replaced the original XM satellites, Rock (XM-2) and Roll (XM-1), which suffered technical problems and have since been powered down -- though they serve as backups if needed. Rhythm and Blues are positioned in the same relative locations as their predecessors, over the east and west coasts in stationary geosynchronous transfer orbits.

Coverage, red is Sirius, blue line XM.

The only stationary orbit possible is over the equator; you can't actually park a satellite over the US east or west coasts.  Such orbits are called geostationary orbits, which are a specific type of geosynchronous orbit.  Some sort of transfer orbit would be employed en route to the final positioning, but the final orbit wouldn't be called a transfer orbit.

They should have just stuck with something like, "Rhythm and Blues have been placed in orbits that give each satellite continuous coverage of the continental US."

Fun fact:  You can see the real-time position of these satellites here:  
XM-3 (Rhythm)
XM-4 (Blues)

They should have just stuck with something like, "Rhythm and Blues have been placed in orbits that give each satellite good coverage of almost all of North and South America."

Fun fact:  You can see the real-time position of these satellites here:  
XM-3 (Rhythm)
XM-4 (Blues)

Naturally, they are at 0 deg latitude, but at the longitude of east/west coast, and with the antennas positions so to cover CONUS east to west coast, and very little further north or south.
So the issue is not that, the issue is if Avidyne can make Sirius/XM retransmit XM weather on the Sirius Channel hitherto used by WSI weather when it shuts down end of 2017. Simpson, please advise if this is being considered.
