@Mike Wyatt posted:You probably have done this, but weak LC remote batteries will act like this. Changing triple A's is a lot simpler than trying the layout to find poor connections between sections. Not just voltage but high voltage is important.
I had a Universal Remote that kept losing signal, with fresh (the finest *** Hardware) batteries. I sent the remote to Lionel, who returned it saying nothing wrong, but "we don't recommend this brand of batteries". They hit the can never to return. Now, I change remote batteries at the first sign of signal loss, and only use name-brand cells. (Note: I have seen problems lately w/ D***C***s leaking.)
I agree that batteries are key. BTW, I don't buy Duracell or Costco Kirkland batteries anymore. I'm pretty sure the Costco ones are rebranded Duracell, and they both LEAK! Battery leakage warranties are a joke, try collecting on one sometime!

1. One would think that the LC remotes have a minimal antenna in them because of their size. So, not holding the remotes up high enough - at say waist level or by a child at a train table - can be a signal-loss problem especially on LC and LC+ locomotives. (The TMCC/Legacy control system relies on antennas in the loco for receiving signals- the TMCC ground relies on the track connection through the power plug ground prong and the house wiring).
I think you may be mixing the command remote links with the track signals, TMCC/Legacy have exactly the same track signal characteristics, it's FSK at 455khz center frequency. The track signal has no direct relationship or connection to the remote to command base communications signal characteristics or frequencies.
The TMCC CAB1 communicates to the command base at 27mhz, (and oddly, to the TMCC PowerMaster at 27mhz as well). The CAB1L & CAB2 communicate to the command base at 2.4ghz.
