I’m sure the process to fit a decoder to a kit built 0 gauge loco is fairly standard. I tested the sound file and changed some CVs using the ESU decoder tester and Lokprogrammer. All was well. I then fitted a 4 ohm speaker and wired the pickups and Maxon motor (ABC). The chassis was then placed on a rolling road that was wired up to my Lokprogrammer to synchronise the chuffs. I started off at speed step 2/28. To my surprise, the sound volume was almost inaudible, even though the volume cv was set to 100%. Any suggestions on what might be influencing the sound reduction? I took care to check the soldering of the speaker wires and the speaker is in a 3D printed sound chamber. I find this aspect of our hobby more time consuming than I expected!
