  1. I can confirm that my latest ETH 47 project ( which we refer to as the Mid Norfolk 47) does indeed have both roof fans. Set CV155 to 0 for a normal fan or 1 for the louder one that the Generator 47's had. Bif
  2. Roy, I will check properly tomorrow but I’m fairly sure my MNR 47 project does still feature the choice of a normal roof fan or the very loud ones that the ‘Generator’ 47’s had. Changeable via CV from memory. I will report back on that asap. And just to correct a point that Charlie made above; it’s not necessary to change CV’s for a 47/7, the extra sounds are enabled by default. I’ll send him a company memo on both counts!
  3. Just in case the info hasn't made it to the website yet, the configurable sounds are as follows. This also applies to my new Bachmann 117 chip; SV1 / CV155 to 0 for high horn type A SV1 / CV155 to 1 for high horn type B SV1 / CV155 to 2 for high horn type C SV1 / CV155 to 3 for high horn type D SV2 / CV156 to 0 for high horn type A SV2 / CV156 to 1 for high horn type B SV2 / CV156 to 2 for high horn type C SV2 / CV156 to 3 for high horn type D Set SV3 / CV157 to 0 for firebell type A Set SV3 / CV157 to 1 for fire buzzer Set SV
  4. Philip, As you say, definitely a strange one this, but in my opinion it must be related to the Powercab as the chips didn't do it when tested on Charlie's system, or when you pulled the mains plug. I suspect there may be some mains-borne interference on your supply. Daft as it sounds, and just for investigation purposes, try plugging the Powercab into a mains socket on a different output from your consumer unit (eg the garage or upstairs if it's normally downstairs or visa-versa) or even next door or at a pal's house. You could also try an interference filter. You can get these sty
  5. I need some ‘slinger’ cranes to finish off a Cambrian Salmon wagon I’m kit-bashing. Does anyone do decent 3D printed ones yet, can you still get the Genesis ones, and / or does anyone have a set to sell or swap? Thanks, Bif
  6. Good news! I have a high quality recording of the fan of 47401 and this was a feature of my v4 version of the 47/4. On that, you could choose between a normal fan or the much louder electric fan from 47401 just by setting CV48 (0 normal, 1 for electric). I must admit it’s a feature I had forgotten all about until I read this post. I’m just in the process of adding the feature to my more recent ETH 47 sound project (referred to as the Mid Norfolk to differentiate it from my earlier one). Again this will be user-selectable via CV (CV155 this time as it’s a v5 chip). Bif
  7. A handful points from me; Blu-tac is not a good long-term solution for making speakers airtight, I always recommend PVA glue instead. A simple but very effective solution for speaker hiss is to drape a layer of felt or similar material over the speaker. It kills the very top-end frequencies but keeps the important bass and mid-ranges intact. Hiss is always more prominent when the speaker is in the top and / or facing upwards than in the tanks and / or facing down. Bif
  8. In that case I feel you need to stretch your imagination a bit further :-) If it was so easy then why are there not dozens of sound programmers producing competing high quality sound chips at knock-down prices? Let us explore the path involved in bringing high qualty loco sounds to market; You need to invest in a high quality, multi-channel solid state recording device. Two actually, in case one fails on the day you paid £1000 to record a loco. Ditto with microphones, cables, boom poles etc. You need a few years experience to work out where to put those mics to obtain
  9. I am happy to announce that my sounds for Bachmann's London Underground S stock are finally ready. The sounds were all recorded 'on shed' and on the Metropolitan main Line with the assistance of Transport For London. They will be available as both a two-chip matched pair and a single chip plus Lokpilot (non-sound) matched pair as a more economical option. They are only available on v5 at this time (ie v4 reblows will not be available). The units sound great with a standard 20x40mm speaker but I've also heard them through a Zimo double-dumbo and one of our 'slab' speakers and they sound equally
  10. Oh, and I’m not sure what caused the lag when departing, but it doesn’t do that normally, no.
  11. The video is of a work-in-progress version of my S-Stock sound project which is not quite finished yet. We’re demonstrating it to give people a taste of what it will be like. We’ll do the usual video of our own once it’s ready. There are only three cars to make it quicker and easier to demonstrate on the stand. The inter-car wire is indeed for the door lights, which were installed for us by Richard Croft. The final demo model will have the wire hidden, passing through the corridor connector. Everything was recorded officially, from a real S-Stock train on the main line and at a depot. Hope thi
  12. Well spotted Carl, the dreaded cut and paste error. The last line in the 'enable' list should say CV363 = 27 as per the corrected bulletin below. Regarding the noisy pan servo, someone at Railex told me that those on the Roco locos are near silent in operation. 90 reblow v7a for bachmann loco-Bulletin.pdf
  13. As Charlie correctly states above, I have finished updating the 90 sound project to suit the Bachmann model. It's now at version 7 and available to order from DC Kits as normal. The speaker Bachmann have used sounds better than previous examples. It's ok but not outstanding. The lighting configuration is far better than previous Bachmann models and has allowed me to set the loco up for light engine and DVT / train modes, with directional cab lights, and day and night time running in any mode. The only thing I've not been able to do is parking mode with reds at both ends, due to the unusual way
  14. The speaker sounds better than I expected but there’s little or no bass to it. Fortunately for them you can get away with that to an extent with an electric. It sounds not too bad at all overall. Full credit to Bachmann for the speaker pre-fit, independent lights and pantograph innovation though. It makes the Hornby 87 look positely prehistoric from a sound and light point of view. We’ll be exploring the pissibilities for speaker improvement over the next few days. Bif
  15. Well, not quite as soon as they hit the shops, but not long afterwards. We now have one on the stand with a v5 chip and functioning pantograph. I need to spend a few days tweaking the settings to suit the lights, motor, speaker configuration, pantograph, etc. I’ve already updated the sounds themselves to take advantage of the v5’s capabilities (higher quality sounds, spirax valves tinging with no hiss in-between tings, choice of two different sets of playable horns and so on). I’ve also set them up to work as a matched pair with my DVT sound project (my 86 and 87 are similarly paired with the
  16. There will be little or no difference in the F key layout between v22 and v23a. I think 22-23 was the addition of the manual brake (still on F5). 23a was CV tweaks necessitated by the v5 chip, which didn't affect the F key layout. The severity of the brake is a user-selectable function controlled by CV179. If you increase the value it will make the loco stop more quickly. Maximum value is 255. Hope this helps, Bif
  17. The Class 40 is probably my least favourite of my own sounds!
  18. Another reason for using two chips is that the two, not being perfectly synchronised in time, run in and out of phase and ‘beat together’, recreating the same effect you get from two real Deltic engines. This would be difficult if not impossible to do with a single chip running two sets of engine sounds at once (which can be done).
  19. Neil, Sorry for the slow response. If you change the following CV’s, in order, it will take off the auto fade-out on F19 and the cab light switch sound associated with it (which isn’t on F20, so it just makes them the same); cv31 to 16 cv32 to 3 cv385 to 0 cv400 to 0 Hope this helps, Bif
  20. Yes it will, and v3.5’s as well.
  21. Hasn’t the EMT one I did for the stand got EM2’s in it?! I’m sure it has. Get it out of the stock box in your living room and try it!
  22. This is exactly what we found before we started fitting them with better speakers. 68 engines are deeply bassy and if you play the sound through ‘normal’ speakers, and even speakers that five years ago were considered to be state of the art, the results are disappointing. Change to an EM2 (if you don’t mind a bit of milling) or a Zimo double-dumbo (if you don’t) and the difference is remarkable. I would recommend the EM2 every single time for the 68 though. Bif
  23. Yes just to confirm I can put any of my sound files onto any ESU chip, so a Leyland DMU for the Dapol 121 on a 6-pin chip is no problem.
  24. To answer the various points; Tri-mode would be tricky but probably do-able with the ESU v4, but more readily achieved with the next generation chip which I suspect isn’t all that far away now. It may be ‘all electricity’ but there’s a world of difference between the sound of DC and AC traction motors, for example, so it is worth doing. On my IEP you use F1 as normal to start and stop the prime mover sounds (diesel or electric) and another function to switch between the two. You can start up on either, shutdown on either, and switch between the two at will, on the move, all as per
