Some of our modular layout club members were having problems adding their MTH engines to the club's remote. There were some spots on the layout an engine would add and other spots it wouldn't. We had similar problems when we were using a Rev I TIU but not since we changed it out with a Rev L.
I took a PS2 engine to the layout and did some signal strength checks. Our outer loop is connected to Fixed 1 on the TIU. Signal strength readings were 8's, 9's, and 10's. No problem there. The inner loop and yard are connected to Fixed 2. Signal strengths were 1's, 2's, 3's, and 4's. I moved the inner loop over to Variable 2 and set the channel to fixed. Now I was reading signal strengths of 6, 7, 8, and 9.
It appears Fixed 2 channel has lost some signal output. Is it normal for a signal strength drop to affect only one channel and not the others? Are there any components that can be replaced (I'm pretty handy with a soldering iron) or will it need to go back to MTH?
