I have a TMCC Cab 1 Base and Remote. I have used it many years for the "Christmas Tree" layout on the first floor of our home. The system functioned perfectly on the first floor, and was able to communicate from the remote to the base from the opposite side of the house (40 feet away)
I have set up a "temporary " loop in the basement on folding tables. The system has a very limited range in a direct line of sight of about 15 feet...
I have replaced in the remote the batteries with no improvement.
Any ideas?
