  1. Hi Bob, I can probably help. PM sent Best regards, Paul
  2. Have a look at this thread, it will help you to understand how sound will operate on DC analogue. From an operator's point of view, the way the control knob/voltage regulator is operated is the key to getting it working satisfactorily. Best regards, Paul
  3. Of course NCE will accept PowerCabs for repair. Not only that, but it's usually a pretty quick turn around and modestly priced.
  4. Ray, Yes, in parallel they are, and that's OK for the decoder types you are likely to be using. But some ZIMO decoders have a recommended minimum impedance of 8 Ohms. The miniature decoders, MX648, MX649, MX658N18, MX659N18 and other miniature types require 8 Ohms if you intend to use volume at the max. ZIMO put that info with each decoder and in the manuals. Most exclusively 0 gauge users will not encounter these types, as there is normally enough space to fit 'standard size' MX644, and MX645 types (as most usually used in 00) or the
  5. Glad to help. In case you hadn't worked it out, I created the original custom sound project for the SLW Class 24 and all the updates since. PowerCab v Prodigy. This is a slippery slope to tackle, but here goes The outward similarity of the two systems goes no further than that, operationally. Both will operate the SLW Class 24, but each in their own way. Having operated sound equipped models at exhibitions for long durations using each of these systems, I find the PowerCab to be the more intuitive of the two and capable o
  6. You will need a Plux22 decoder. I would recommend ZIMO for finest control. Although other brands will fit, the model was developed for ZIMO decoders and in conjuction with the ZIMO factory in Austria. Sound or non-sound ZIMO Plux22 decoders are offered by SLW pre-fitted with all CVs adjusted for optimal performance and full use of all current and any future features. No need to even open the model, just pop it on the track and start operating. The official SLW Class 24 sound project was developed using an NCE PowerCab for all operational testing, so you can
  7. You will not get coasting without sufficient momentum set in CV 4. See this post as to why you should never use the PowerCab momentum button with any sound project. Best regards, Paul
  8. An other vote here for ZIMO. Nothing too special about a Hornby 48DS from a DCC perspective, once you've snipped off the socket provided, and you can get more in that you might think. You can fit a ZIMO MX648 miniature sound decoder, speaker and high capacity Stay Alive in a Hornby Ruston 48DS. Best regards, Paul
  9. That 'run away' tendancy coupled with what you said earlier confirms that this is most likely a poor signal path. (though there are other reasons why a run away can occur) Explanation: The decoder detects power but there's no clean DCC signal so defaults to DC analogue mode. On DCC, all connected track is fully powered all the time. Decoder 'sees' a full power request and sends max voltage to the motor. Best regards, Paul
  10. Dave, Yes you have, just found them in my Spam folder. OK, address 10 has no adverse connotation that I know of, save that for no explicable reason, some decoders (usually older, cheaper models) refuse to accept particular, apparently random, adresses. Not my experience, but this has been reported rom time to time on RMweb and elsewhere. Have you tried programming a different address than 10?* Most of my ZIMOs will programme OK with Stay Alives connected, but occassionally, and usually it will be one of the miniature families like the MX648, a de
  11. Dave, Try temporarily disconnecting the Stay Alive capacitor during programming/re-addressing. Sometimes these can disrupt the process. Service mode programming (on Programming Track) normally terminates with a power re-cycle (off then on) which helps to make any CV changes 'stick', but that brief power down will not happen if a Stay Alive pack is connected as it's purpose is to maintain power to keep the decoder 'alive'. A supercap will keep a decoder alive for up to a minute if the power drain is small. Your sound project does not have the programming lock
  12. If you are referring to Swiss Mapping, then you are correct. The feature was first developed for some complex Swiss loco lighting regulations. There have been seen significant improvements in functionality with increases in SM groups (currently 13 on sound decoders) and the ability to use one of 5 user-selected 'dimming' values for each individual output. However, you will need each individually controllable light to be separately connected to a different function output on the decoder*. Once that's achieved, it would be simple to allocate different array paterns to dif
  13. Digitrains have just posted a clip of the factory sound fitted GF 8F.
  14. This is how it looked on the day I recorded the sounds for my DCC sound project. Best regards, Paul
  15. You may need to cut then restore power after CV8 =8 to make the reset 'stick'. Best regards, Paul
