I am not expert enough to comment on how many ADAHRS you can put on one data bus, but I think the answer is just the single ADAHRS-200 with the optional 201. Otherwise, there would be no need for the 201 -- you could just use 2 (or more) of the primaries, so why would they make 2 different...

Well, the third party that installed my system really didn't do very good job, even using sub-standard wire (for aircraft anyway), and it is not a tidy job. The shield jackets were quite a long distance (about 5") from the D-sub connector, but that had not been changed. I remade a few...

Trying to summarize what I've read in this string: after finding a spot free of significant magnetic interference, the initial ground compass calibration is best and easiest performed using ground track (always provided by GPS), but providing you move far enough for a decent gps heading and stay...

Thanks for that. I'll inspect/redo those grounds first. I did see that in general the shield connections were in the right overall configuration per the manual (though not "as close as possible" to the connector), but I've found some bad crimps elsewhere. Hope it's there. .

I have a dual screen HDX system with SV-intercom-2S, but my nav/comm is from a Garmin GTN-650-xi. This is an existing installation (from about 2020), but has recently begun giving an overpowering squeal when I hit the passenger side push-to-talk button,. The squeal starts immediately and is...

Thanks Bob. Just to be clear, I was talking about the wires from my panel to the controller, not controller to pitot. But I take it from your experience that just straight runs of unsheilded appropriate guage M22759 is suitable?

Well, this is probably a pointless addition, but ... I was considering adding a wet compass for awhile -- despite dual ADAHRS -- just for redundancy in case of something like a common mode or data bus failure. Also, to just avoid the errant FSDO or CFII guy arguments. But to the original...

I was wondering what is "proper" pitot heat wire? It appears that 14 gauge is probably the minimum red/black power wire size for my length, with 22 guage for the white signal wire to EMS pin 9. Although some references advocate sheilding for nearly all applications, I didn't see mention of...

Not that I have heard of, but there is always a first time, especially if careless. I think with serial numbers tracked, smallish aircraft community, avionics installation generally professional and controlled, and felony offense for aircraft tampering, theft has not been a big profit center...

I have a dual panel HDX system, with the airplane stored in an unheated metal T-hanger hanger, concrete floors but South facing doors that aren't particularly tight, in Southern Michigan. Winter has a lot of high humidity, usually in the range of 20-40 (F), with bouts down to -10F or so or up...

I'm not sure this is the same issue, but I've had intermittent connection issues with HDX panels/Foreflight/iphone that I haven't sorted out. Sometimes Foreflight doesn't see the connection even though the phone seems to be connected. My wifi dongles are directly on the back, so signal...

Yes, the new Dynon Com Radio (Com 1) would be controlled by either the HDX panels (except volume) or the new SV-COM-Panel (incl volume), and the GTN650 Comm radio (Com 2) would be controlled by the GTN650 as it is now. The PMA-4000 would co-ordinate them so both don't transmit at once, and...

That system sounds very useable. My GTN650 likewise communicates with the Skyview network via a ARINC-429. The problem I would face in adding a Dynon radio is that I have panel real estate for an SV-COM-PANEL, but don't have panel space for an SV-COM-PANEL and a GMA-240. But, with Bob's...

I have come to want to add a second comm radio. It would be easy if comm 1 was a Dynon unit, but that is not the case. I have an EAB installation with a GTN650 IFR navigator (that provides NAV/Comm), dual 10" HDX panels, and Dynon intercom panel (and the other supporting Dynon stuff, e.g...

Thanks. I'll get to work on an ADAHRS move!
