So having invested in three HM7000 with sound decoders, I after a few teething issues - yes read the instructions - I think these are an excellent product for someone like me, who is not an electronics wizz and still trying to grasp all the function variables. I'll get there in due course. What I would like to see is a simplistic guide for the sound profiles that would help me select the most appropriate sound profile for Locomotove types that are not listed. So for example I have a Fowler Class 4P (R2224) fitted with the HM 7000. Clearly as these were all scrapped many decades ago it is unlikely there is any sound recording that could be used from life. But which HM7000 profile and sounds is best to use? Likewise my R3833 Chamossaire being a Class A2/2 or A2/3. I am sure there are others out there that have a similar desire and would appreciate guidance in this manner
