This is slightly different from running on DC this is running on DCC but using DC purely as the source of power for the chip. The actualy control signals are sent via bluetooth/other means. I changing direction or power on the DC controller is not how the loco is controlled.

Do Blunami and HM7000 share the same architecture, are they the same thing marketed by different companies, seems odd they're having similar issues...

But I will point to people who post here say that your interpiration ofDC operation is what was meant, who stated at the time on the Hornby forum that my interpretation is exactly what tri mode means. So it seems to me that this 'running on DC' option has become a rear guard action to defend the tri mode marketting.

'Stance now being taken' which was after the product was purchased on the basis of the stance that was in play at time of purchase!

Could it have been faulty out of the box? Sounds like it never worked from the start

Thats the spin, but the same people saying that were enthusiastically extolling the virtues of that feature around launch time. Its only since launch where the suggestion of an issue has occurred that this interpretation has come to the fore. (previously is was cheapmcontrollers might not have the power to power up the decoders or support sound) The meaning of tri mode on the box is pretty clear, that option is what is meant. If its such a minor '...you might get away' why put it on the box. If it's option 1 apparently '...well you can do that if you want but no other decoder chip supports it and in fact they disable it' why put it on the box??

And I suspect what those defending the big red box don't get, is its not people wanting tonhave another whack at Hornby, its that they are frustrated at seeing a product that promised to be ground breaking falls short. It might be worth having some mini polling here. I bought a 21pin sound decoder to dabble with, it fitted it to a Bachmann 66 and I've used it (not anymore) on a bog standard gauge master combi with no issues. I always had the power turned on and up before putting the loco on the tracks as in my mind any spiking or werid fluctuations are likely to occur when you adjust the controller but ho hum. (What happened to those wave form screen shots could we see one for a Hornby approved supply v say the combi)

The fact is it was marketed by many (included yourself over on the Hormby forums this year) as 'no need for an expensive DCC controller just turn the power up.on your existing DC controller'. Now there's been a considerable reverse ferreting and claims that the chip were never intended to have this functionality. Do we actually know if the 'failure rate' is actually above that of a standard chip working on DCC? We seem to have 2 YouTube claiming their Chips have "blown" (I like tonsee how that was diagnosed beyond simply they don't work), and some people say the app now fails to find their chips (which could mean they're blown but could be something else entirely). I doubt Hornby will ever 'solve' the issues or even address it publicly (the current approach seems to be reverse engineering the website and pretending they never said that you could use DC to power the chips). And further to this is the system under further development? Are there plans to update the app? Or is it just new sounds?

The 2nd, but there's been some sort of smoke and mirrors going on claiming that 'tri mode' on the box refers to the first.

Just wonder if the lift off roof would make a different to the available height

So Inhave to ask, will a Hornby Bluetooth sound decoder fit in the new 66?

Public admission there's an issue is more what I'm thinking.

No I don't expect that, but there's been no official statement otlr update about the DC issue.

What is it a month with no official statement from Hornby?

Oh well ordered 779.

You don't think they mean 'this will only work with our own branded cheap Chinese Wall warts and not another cheap.chinese Wall wart that probably come.out of the same factory"

Don't Hornby state that old laptop chargers etc 'spike' and your not to use them 'we don't want any fires...'

Surely we need to see what the output from a 'recommended Hornby dc source' lookslike

Guides I have read people remove the existing enclosure in the loco

I have been looking at them

Anyone ha e any thoughts on a suitable speaker upgrade that fits the Bachmann 66?

Anyone have any suggestions for a beefier speaker suitable for this combination?

I didn't notice because my Bachmann 66 is the same!

Why so slow to disseminate this advice to the general populace?

You keep posting about the latest advice, but I can't find this anywhere, not even a sticky on the Hornby community forums. Where was this advice published and does it affect the warranty of a chip stops working when used on DC?
