Mohammed,
many thanks, I spoke to Garry today. He is a much happier Massoth fan. I am as well as until he got this sorted out I also was a little hesitant in purchasing any Massoth decoders.
I would assume that Garry would need to always have load control active. One wonders if this is peculiar to just his decoders or to other Massoth decoders. Possibly, the issue with the 'LS' shutdowns could also be attributed to load control adjustment?
