I might not phrase it the same but I have similar thoughts myself!. Reading the various forums I get the impression that, for many, the technology seems to be more important than just running trains. In other words, the trains are an excuse for playing with the technology.

Yes indeed: I have found this to be very true. I simply want many of the options available to me with DCC, principally sound (with the ability to trigger some of the indivual sounds, e.g. proper whistle tones, Westinghouse air pumps, etc.) and customised speed curves via direct radio control and battery power. If there was a way to trigger a few of these functions using DelTang (for example) components, this part of my hobby life would be a lot simpler!

For me it's not really about the technology, I do love the simplicity of BPRC it is just a few key features I miss.

We seem to be of a similar mindset on this!

I use Paul Chetter's sound files from Digitrains, but other than being able to use the whistle as a real engine driver would, and switch between the light engine and loaded train sound sets/speed curves, and to decide whether the Westinghouse pump is in use (which could be linked to the sound sets, I suppose) I am not bothered about the other features: they can be automatic or simply switched off as far as I am concerned. It there was a way to switch two or three functions on a DCC decoder via an external switch, such that I could use a function on the Deltang Rx, then I would be very content with that!

Well, it seems that I may be in luck, as Zimo engine modules have a facility for up to 3 functions to be externally triggered (and more for the large scale modules). More investigation is required - I need to find out if the triggers are "pull down" or "pull up", for example - and I will still need to use Decoder Pro from JMRI with a SPROG to program the module, but it seems that my investment in Tam Valley's Dead Rail System and a Tablet may have been an expensive dead end! Combining DCC and DelTang may be a possibility.

Would you control the motor with the Rx and the lights, sound etc. with the engine module ?

If only it were possible to do what you want. Sadly you cannot yet do so with off the shelf equipment.

Maybe I'm reading this wrong, but why the need for the Deltang receiver? Previously you mentioned that you were using a Tam Valley receiver with battery power connected to an appropriate DCC sound decoder in your loco. If this is so, then you have the ability to trigger the individual sounds, use a customized speed curve, etc as all these features are provided by the DCC decoder.

You've mentioned that you want wireless DCC access. With an appropriate throttle, you can get that. As an example; I model in On30, but use similar equipment to what you have mentioned.

In the locomotive;
- Tam Valley 916 mhz receiver.
- ESU LocSound DCC sound decoder.
- Single cell lipo battery with 9v pololu step-up converter.

On the workbench;
- Old laptop with JMRI installed.
- Sprog DCC command station/board.
- Tam Valley 916mhz transmitter.
This is used to program the decoder. It's not used when running a train.

The throttle;
- A CVP AirWire T5000 throttle (channel 16 on this throttle communicates with the Tam Valley 916mhz receiver directly).
This throttle will happily run the locomotive, trigger the sounds via function buttons, etc. It can also do basic CV based programming, although I prefer to use the laptop/sprog combination for most of my decoder programming, as it's more user friendly.

What I m trying to do is not have wireless DCC, but RC with some of the features I can only get currently via (in my case) a Zimo DCC sound decoder. I am happy to have the (literal) bells and whistles of DCC, alongside the sound, speed curves, and things like the exhaust beat sounding harsher when the back-emf changes, but frankly the rest of it doesn't interest me. If I can get what I want without a command station, transmitter, and receiver per engine, then I am a happy bunny.

Not sure if I can get the t5000 throttle with European frequencies.

The system I described is not Wireless DCC, but R/C DCC for want of a better term.

The Tam valley receiver / DCC sound decoder (Zimo or any other) / T5000 throttle provides direct R/C control of the locomotive (via any features of your chosen dcc decoder you choose to use and no command station).

The T5000 throttle talks directly to the tam valley receiver via radio. There isn't any command station, and the tam valley transmitter is not needed. You are always going to need a receiver of some sort per engine.

As I mentioned in my previous post, the laptop / sprog / tam valley transmitter combination is only used for easy programming. It's not needed to run any trains, and you can program individual CVs via the T5000 throttle instead if you want.

Of course the biggest stumbling block, if it is important to you, will be euro frequencies. There is the same issue here in Australia, but generally ignored by most due to the low power / relatively short range of the T5000 throttles for home use on 916mhz.

It's probably my miss-understanding of what you are trying to achieve, so even if this info doesn't suit yourself specifically, hopefully it will be of use to somebody else.

John.
I think what Simon is wanting to do is to control speed direction and lights etc with the Deltang R/C and have a working interface with a DCC sound system triggered by function commands on the Deltang TX handpiece.
