This is the most frustrating and seemingly impossible-to-resolve problem that I have ever experienced in my 5 decades of model railroading.? I have read all your responses (thank you very much, guys) and done everything you have suggested, yet the problem still persists? Most of my locos are down (the ones I tried to tweak with JMRI).? I can run solo, but having an op session with my buddies is impossible.? Perhaps the problem is that I am NOT a computer nerd.? I understand DCC pretty well after 2+ decades of use, but I have never been a computer whiz (most of what I do with computers is cuss at them...).

What I have gathered from your replies is that this is not a JMRI problem.? I can accept that.? I also don't believe this is a decoder problem, as many of you have observed, and because so many of them, both older and newer ones, from differing manufacturers, are involved.? (I have decided that I will NOT buy any more new decoders until this problem is resolved, if ever).? That leaves the CS-105, and responses on the TCS forum were few and unhelpful.? I've been told not to throw out the decoders, that they're "probably" still good (some have been thrown out, but some have been recovered), and that the problem is fixable - but I have not been told what is wrong, how or why it happened, or what the fix is.? I'm obviously not going to find the answer on my own.? I feel like I have only two solutions:? 1)? pitch the CS-105 and buy a new NCE system, as my old NCE command station worked flawlessly until it just got too old (NCE told me that the cost to fix it would exceed the cost of a new system), or 2)? tear down the layout and sell my equipment, cuz I'm NOT gonna run without DCC.? Being recently retired, I'm now on a fixed income, so buying a new command station will take some time to save up for it.? I have reviewed the manual for the CS-105, and again, can find nothing that I am doing "wrong".? Guess I just need to flip a coin :)
