If they don't want to produce one, it would be nice to at least be compatible with another dual receiver so we can display traffic and weather on the IFD.

I guess this becomes a 10.2.1 request then rather than a receiver request.

In my humble opinion, I think that's a mistake.

With 10.2, we are compatible with the GTX345 which is dual-band. Additionally, L3 has listed our IFD as a compatible display for their Lynx, which is also dual-band.

AviSimpson, thanks for the heads up about those units, but this thread is about dual band receivers.  Support for those units and not a dual receiver makes those of us who purchased an AXP340 wish we bought a product from one of your competitors...

SkyTrax 100 is the receive-only box for ADS-B traffic and weather on 978MHz.
SkyTrax 200 is a transmitter and receiver (UAT) for ADS-B Out and In on 978MHz, using an external GPS (IFD/GNS/GTN) as the position source.
SkyTrax 210 is a transmitter and receiver (UAT) for ADS-B Out and In on 978MHz, using a built-in GPS as the position source.  In other words, this is a stand-alone unit.

The 200 and 210 are not available yet.

Some of us still have hope (faded, though it may be) that all of these products will have an upgrade path to receive dual-band someday.  But for now they are 978-only receivers.

???  Huh.  My preference would have been for a 978 Out transceiver, for the air-to-air capability with my fellow little-guys.  I "settled" for the 1090ES because it was the cleanest solution available at the time I was doing a major panel project.

It is harder and harder to stay a fanboy: Garmin came out with the 345, which is really the perfect box for the ADS-B mandate. I had sold my GTX33 and GTX330 that I had in my planes because I decided to go the IFD540 route, so it was only the AXPs that worked at that time, and there was no information that this would change. Now I lose the MLB700 weather, so I have to buy an MLB100, again with less capability. Cost of the AXP & MLB100 is already higher than the Garmin 345, with less capability and a higher install cost/effort. And as the icing on the cake, the 345 now works with the IFD540, giving better capability than the house brand stuff. Just shows that us early adopters get burned, every time. End Rant.

I replaced my 530W with an IFD540 this month and will be going in in June to have a Garmin 345 installed in my Twin Comanche.  I would have preferred to go with Avidyne ADS-B equipment for the sake of future compatibility, but the Garmin makes much more sense at this point.  The Garmin has many more features than the Avidyne does including tablet display of weather and traffic and dual band ADS-B in, it is a one box solution which simplifies installation, and the cost is lower than the combined cost of an Avidyne transponder and their Skytrax100 box.  Seems to me that Avidyne needs to take a serious look at their ADS-B products and pricing if they are going to be competitive.

I agree that the 345 is a slick product.  Definitely second-generation thinking.

If every receiver was dual-band capable then it wouldn't matter what band we use for ADS-B Out.  (And there are already frequency saturation issues with 1090MHz.)

My experience has been that the ADS-R function of the network is not reliable enough where it really matters (in the traffic pattern at most small airports).  So in order to "see and" I want a dual band receiving capability.  But in order to "be seen" I would need to have a dual-band transmitter, which as far as I know is not offered or proposed by any manufacturer, or I would need two transmitters which some airplanes seem to have.

Just thinking out loud.

Well, there is a TAS solution available. Pricier (perhaps too pricey now for the US market), but a much more complete solution, and it one day will have ADS-B IN from 1090 and ADS-R built-in.

My TAS605 is a real performer, and you can send traffic data to any panel mount device from it, ASPEN, Avidyne, Garmin etc.

And it looks like maybe there might be some movement on the -A project.

It was posted on another thread on this board by Avidyne that they were commiting more resources to get the -A piece tested and certified.

One can hope anyway.  Quite a few customers are waiting for this.

That does NOTHING to help other pilots/aircraft see me.

Imagine that the other traffic only has a UAT installed.  That guy won't see me unless I am transmitting on 978MHz.  (In this scenario, we are both in the pattern at an airport outside/below network coverage altitude.)

Of course, if I have a dual-band receiver that equipment will detect his target and display it for me.  But his equipment would not detect me if I only broadcast on 1090MHz.

My point is that "see and be seen" contains a serious flaw in a dual-band environment.  And dual-band receivers only solve half of the problem.

ADS-R solves the problem at altitude, but most so-called "mid-air" collisions don't really happen in the middle of the air.  They happen mostly in the traffic pattern or on short final when two aircraft attempt to use one runway.  Exactly the place where the network drops you off and says, "Thanks, see you next time."

Of course, most of those places are well-outside rule airspace.  And I am starting to get the impression that there are more "rancher pilots" than the FAA thought.  Those pilots simply won't equip for ADS-B because they don't use rule airspace.  These are the same guys who exercise their option not to use a radio to announce their position, and their airplane probably doesn't have any kind of traffic display system in the first place.

I guess I'm just "not feeling it" this morning.  Sorry guys.

None of this stuff will protect you against the NORDO J3 that pulls out onto the runway when you are on (really) short final, as happened to my wife at an airport under Boston's Mode C veil.  The FAA says "see and avoid" and we need to do that.

I really do think it is important for the SkyTrax to be upgraded to dual band on the ADSB-In  - the Avidyne transponder is 1090 after all....

Agree!  It would also help to finally have the long promised TAS-"A" which would at least display both active TAS IN as well as ADSB 980 -In, but still would be nice to have the option with SkyTrax100 to upgrade to add 1090 IN with our squitter 1090-OUT..

supposedly a software defined radio exists within the existing Navworx/Skytrax box which could activate a 1090 receive function.

However, Navworx appears to have its own issues.  

Such is the downside of purchasing "rebranded" technology.

Tom, I agree with you about the TAS-A disgrace.

While I agree with the desire to have the SkyTrax be a dual-band receiver, it really doesn't matter what band transmitter is installed.

The ADS-B Out message format includes bits that inform the network of the aircraft's receiving capabilities.  So when your airplane advertises itself as being capable of receiving on 978 only, it doesn't matter if that advertisement goes out on 978 or 1090.

The advent of dual-band receivers did not occur until years after the final equipment specifications were set and published.  The people who wrote the specs did not anticipate that market move, so the network is specifically designed to handle single-band receivers.

I expect that in another decade or two, the marketplace will be populated by third-generation ADS-B products, and that virtually all of those will include dual-band receivers.   Unfortunately, we all can't wait to equip.  If we could wait (if there wasn't a 2020 mandate) then there would never even have been first-generation products.

When I am flying out in the boonies (like SW Colorado) out of range of the ground-based repeaters, as I often do, the only way I would ever see 1090 ADSB targets would be with a "dual band" SkyTrax - hence the TAS for active transponder reception.

True, but the ADS-B network (and mandate) isn't designed for you or me.  It is designed for air traffic control, and they don't care about uncontrolled airspace.

Well, "boonies" isn't synonymous with uncontrolled, and for the purposes of this thread (at least my own selfish ones) I'd rather Avidyne see more interest than disinterest in a dual-band solution so they have business incentive to pursue it.

I'm totally with you on that front.  I WANT to add dual-band receiving software to my SkyTrax unit.  I know the hardware is already there.  It's just a matter of motivating NavWorx to make it an engineering and certification priority.

David B:

IDK, seems like Navworx is underwater with magical thinking.  Doesn't some of the "motivation" need to come from Avidyne?

I assume you are saying there is a software defined radio asset capable of 1090 within the existing Skytrax box?

I have my trusty TAS610, which one day will be a 1090 receiver...... So I am not too enthusiastic on the MLB becoming a dual receiver box. I'd rather have it retail for $500. What I however found is that with every additional box, there is significant additional install error / wiring issue risk. So I'd love to have as few boxes as possible. So really the MLB100 should have been built into the IFD540. Makes more sense than the AHRS of the 550, especially as it is stand-alone.

I haven't seen a circuit schematic, so I can't comment on the physical embodiment.  But I have been told that there is receiving circuitry on the boards that are tuned for 1090MHz.  Also, NavWorx makes a device called a TransMON which links their UAT to an existing transponder.  The TransMON contains a 1090 receiver/decoder.  So they obviously know how to make a receiver.

The issue is not receiving the frequency.  The issue is receiving the ADS-B data and piecing it together.

When a UAT transmitter broadcasts, it spits out all of the data at once.  When a 1090 unit broadcasts, it only pumps out part of the data stream on each bust.  A 1090 receiver has to capture and store all of the 1090 broadcasts within range, and then reassemble the data for each target in order to form a display set.

That's why I say it's a software problem, not a hardware problem.

Certainly some of the motivation at NavWorx needs to come from Avidyne (and it does).  I also bug them about it each time I see them.  Not sure how to translate "underwater with magical thinking".  NavWorx is doing what they can with their FAA oversight office.  That relationship can only be pushed so far, so fast.  So I do have some sympathy when they tell me they can't climb that mountain with the FAA right now.  But it doesn't stop me from bringing it up each time.

I understand conceptually what you mean.  A true all-in-one piece of avionics equipment.  But I don't see how Avidyne could produce a unit that is a combination navigator-transponder while still having it be a slide-in replacement for a GNS530.

Regarding Dual band ADSB receivers (and 1090 Out), I see Lynx 9000 (+) and GDL88, but I would love to know if either of these or both are compatible to display on our Avidyne 540's?

Lynx is compatible with Aspen, and wouldn't it be nice if the Lynx would also talk to our 540's - finally all toys playing in the same sandbox...

And now their troubles include an AD.  Published today.  AD2017-11-11

That's a pretty harsh AD for NavWorx.  Assume it does not apply to our SkyTrax100.

SkyTrax100 does not use an internal GPS. It takes the GPS information from the IFDs. So it is still unaffected by this AD.

The AD doesn't seem to accept that the unit can be married to an external GPS (although they indicate that an AMOC will be available to allow such).

The best (most technically correct) answer for the SkyTrax100 is that this part number is not listed on the AD.  So the AD does not apply to these units.

Actually, I think it is about as cooperative as I have ever witnessed from the FAA.

1) They waited to publish the AD until after NavWorx had submitted the certification data package for the new units.
2) They gave the AD an effectivity date that allows the FAA enough time to approve the submitted data.
3) They gave enough compliance time for operators to perform an orderly upgrade.
4) They said that there would be AMOC coverage available for solutions not currently listed on the AD.

I have never seen them be that nice to a manufacturer.  Sounds like they reconsidered their original position on the topic quite a bit.

I don't know that "cooperative" and regulatory fit in the same thought.

All in all, this will generate costs to Navworx' customers (as posted on the Navworx web site), and probably tarnish future sales.

I hope they survive.
