  1. I had a development copy of a DCC operating software to play with, written by a Train-Sim guy, which had an optional throttle with a brake slider. This method let you cut the throttle without affecting loco speed, until you applied the brake slider. The retardation was proportional to the amount of brake applied. If some throttle was left on and the loco braked below this speed, when the brake was released it would resume that speed. Very realistic operation. This obviously modified CV4 relative to the amount of brake.
  2. For years I have used simple heat shrink sleeving warmed at the ends just to shrink it enough to keep it from falling off. I have never had decoder overheat to the point of destruction but I have had them get hot enough to self shrink the sleeves. The safest way is to leave them unclothed with insulation applied to any metal parts they could come in contact with. Some of the sound decoders need to shed heat from the choo-choo noise amplifier chip.
  3. It sounds like the decoder is seeing the asymmetric signal as plain DC and it is causing DC runaway. Does ADCC work if you disable DC running in CV29.
  4. To respond to the comment about jerky movement and needing a lot of welly to get going - I put a circular neo into a ringfield and it is as smooth and responsive as I could wish for, however putting a pair of arch shaped neos into a different ringfield gave the same result as yours, in that it would not run at less than half throttle and slow control was impossible so I reverted to a new normal magnet set.
  5. Several decoders have a braking facility which modifies the CV4 value by a factor, hence when the allocated F key is pressed it applies this factor to CV4 providing the illusion of braking. in a software application this can manifest by way of a separate throttle and brake slider. When the throttle is retarded nothing happens to the loco speed (coasting), until the brake slider is applied, which enables the throttle setting and applies a factor equivalent to the brake slider level. If the brake is released then the loco reverts to the speed set by the throttle, hence you can brake against the throttle to check speed for a signal or points crossing.
  6. The other way for build continuity and short checking is to wire a buzzer to a 9v battery with croc clips on the ends of the wires. Clip the wires to the rails or bus and if you cross a drooper to bus wire as you go then the buzzer sounds. No noise no problem, providing you test the circuit by putting a coin across the rails at setup.
  7. Contact Hornby and see if they will replace it under their no quibble 1 year warranty. Lost your receipt probably ...
  8. Some folk have used a neo magnet just placed on the existing one in attempt to prove/improve magnetism fade. A simple test is can you pick up the motor with a screwdriver blade attracted to the magnet. If not then send it for remagnetising - several folk provide this service.
  9. Unscrew the socket and look at the underside for solder bridging. Usually with the blanking plate in any error here does not matter but with a chip installed isolation between pins is essential.
  10. Look here for my installation to an early A4. http://www.halton96th.org.uk/article7.html
  11. My local shop had not had the 2020 catalogue delivered yet, although oddly it was on the shelves in Tesco and WHSmith, so they rang Hornby to pre-order a Rocket for a customer only to be told they were already sold out. The other odd thing they are only scheduled to visit Margate to put their an usual annual order in this Monday, so how is the average model shop supposed to cope with a chaotic system like that. The Rocket is only one of hundreds of new items so I would like to see the business model that enables a range to sell out before the retailers get a chance to bid their orders.
  12. Steampunk is the future as seen from the past. The tech presented has to be feasible future design as seen from the current past era and critiqued from the future present. Fetch t’inter-web info on Heath Robinson and Emmett as simple viable examples. Sticking a few cogs on something is not steampunk. Hornby chose the wrong ‘consultant’ for this venture. A little basic research would have immediately flagged that up to them before committing to their poorly presented idea of this complex genre. Try this... https://pin.it/jmnnwg2uanyxl4 and compare with the German DRB19.10 real loco. For steampunk real tech look at this ... https://pin.it/6kmaylpbdhqeg7
  13. Normally it would be CV2 but TTS does not support this adjustment.
