I had the same issue with my MRC sound units in a Kato Sd-40-2 and an Atlas gp35. In order for it to accept some programming I would have to Unlock it on the programming track each time I would adjust the volume or change the horn ETC>
QRNational4101 Hi all, I went through to adjust volume as stated in the manual. No matter what I do, I cannot get any volume difference, from 0 to 16 volume, it is still the same. I would change the master volume CV setting, escape out of program mode, then go back to it to find the number I had entered just moments ago, was gone and the default number was there. Thanks, Anthony.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.
(Modeling Freelance, Eastern US, HO scale, in 1962, with NCE DCC for locomotive control and a stand alone LocoNet for block detection and signals.) http://waynes-trains.com/ at home, and N scale at the Club.
Yes I can understand this, but as I said, a fellow club member has the same decoder, in the same loco and you can hear it from at least 4 metres away. I'm not sure I just have a dodgy decoder.
The small speaker that will fit into N scale locomotives severely limits their volume, and there's nothing you can do about that.
The only N-scale model I have ever known to have adequate volume to be heard more than just a few feet away was a DD40X with dual speakers, because there was room for more than the tiny one on the MRC decoders.
I have recently purchased a few N Scale MRC sound decoders, one SD60M, one F45 and one SD80/90 sound decoder. Upon installing them as the instructions say, i found the sounds to be very quiet on all three units, so I went through to adjust volume as stated in the manual. No matter what I do, I cannot get any volume difference, from 0 to 16 volume, it is still the same. I would change the master volume CV setting, escape out of program mode, then go back to it to find the number I had entered just moments ago, was gone and the default number was there. Now I can understand one decoder, but I have had the same problem with all three, while a fellow club member has three SD80/90 sound decoders that worked fine straight from the pack, with a volume level you can hear from a distance. Has anyone else had this issue, and how do you go about solving it? I’m sure I’m doing something wrong, but even my friend tried and had the same problems. Any help would be appreciated.
