It looks like a Bachmann decoder, in colour, etc...

So, it will be another make....but my system doesn't read back CVs, so no use looking there.


There are not that many direct decoders so it should be relatively easy to narrow it down.
If its in a blue wrap then its either a DCC Concepts Zen Nano or 360 (the latter is almost square) but then the blue wrap invariably has DCC Concepts all over it.

If its a green pcb with the components clearly visible it could be either
- a TCS decoder - 17.83mm x 12.04mm according to the leaflet on a DP2X-UK I have just bought but a number of web sites refer to it as 17.5mm x 11.7mm e.g. http://www.bromsgrovemodels.co.uk/tcsdecodersdp2x.htm - seem to recall their was reference some time back of it having got larger. -
or
- a Lenz Silver Direct https://www.modelrailwaysdirect.co.uk/L ... -10330-01/ and is stated as being 19mm x 13mm

Not aware any other small direct fit decoders.

Hi Mike.

Thanks....

I do remember it has a small purple wire, like the Gaugemaster (but in theory most if not all ofthe decoders should have a purple wire!)

It is not wrapped, so unless any wrap was removed before it came to me....

I will have to dig it out sometime, and take a piccy! ;)

Fitting decoder to Adams radial is a simple job. Remove body, remove coal and rails, look inside you will see a piece of plastic held in by two screws, remove and you will see a vast chamber with holes in the bottom for ventilation that will accept most decoders. :D :D

Thanks BRJIM.
As I said earlier on in my thread I swapped the Radial for another locomotive thus ending my problem. You shouldn't have to go to all this trouble with something that has a design fault and that you have paid good money for.
For some reason the thread kept running after I stated that I no longer had the locomotive.
Thanks for your response.
With my best regards.

BILL.
