***They say they have - however I still see the same failure problems with them far too often.... most I see have already given off their "smoke signals" when they come in, so I haven't played with them too much recently....

Did you reading it in programming track mode (press: Programme, 4, enter, 1)?

*** It was worth a try, although I still think without CV's 5 and 6 being programmable it'll never be more than very little value as a decoder.

No, you will not be doing anything wrong - I suspect that its still a little quirky as the basic decoder hasn't really changed much... NCE is tested and compliant and the Powercab is without any doubt at all the best "programming handset" on the market for difficult decoders by far due to its quite high programming track current abilities - it handles even the most troublesome decoders with little problem, so I know where I would be looking for fault.

Mind you there;s not much worth reading on the H decoder anyway - Start voltage and momentum are visible effects so should be able to be programmed on the fly using POM, and there's nothing else worth worrying about in the decoders CV's other than address and CV29 configuration. CV29 should default to 6 for short address and 38 for long, and you have it covered....

***You cannot adjust anything useful on this chip Rob - only CV1, 2, 3, 4 and 29 (CV29 in part only)!
