like many of us, I started with TMCC and graduated to Legacy when it became available. I connected the TMCC base to the Legacy base using the Y cable so I could continue to use my CAB-1's.
Have been operating flawlessly for over 10 years.
Now have 2 CAB-2's and a CAB-1L. Don't use the CAB-1's much anymore.
So when I went to install the LCS WiFi module, I disengaged the TMCC base. The LCS install went flawlessly. However, upon powering up the layout, I realized that parts of the layout were getting a bad signal. I could not generate one idea other than reattaching the TMCC base. So I did that.
Everything works fine now. What???
