I went through and tried to find an engine I had put one of these boards into.
So based on that info- we are talking about the same board.
The remote based on that ID would be cs-6308244900-p LIONCHIEF REMOTE / FOR 6-38244 SANTA FE RS-3
Again this came from Santa Fe RS-3 LionChief Remote Control Scout Freight Set SKU: 6-30207
This is the parts and support site specific to that set https://www.lionelsupport.com/...ol-Scout-Freight-Set
I did find that either using the universal remote or using hotspot mode- commands were slightly delayed and/or it might take a few presses sometimes for the engine to respond. It appears to be communications issues specific to that board when not using the original OEM remote.
Further, a local friend who sells and buys tons of Linchief, went recently through a battle with Lionel parts trying to get the right remote for a given engine. Lionel sent several "wrong" boards, it ended up sending the engine to Lionel for them to match a remote to it. I'm not saying this to knock Lionel- just explain that I have seen how even just ordering parts- it can be a challenge to get the right part.
Again, yes, I'll acknowledge, something specific about that board seems to be it really wants the original matching remote. I did not get odd sounds but my layout is only 10x14.
