Richie, yes, both loops are connected and receive signal for Legacy and DCS.
SF 3751, there is a good amount of space in between each feeder. I did not run enough when building my layout, but signal worked fine until about two weeks ago. The signal cuts out noticeably in the same spots. DCS signal on my layout has always been problematic, so the TMCC lockons must be the culprit.
Thanks for all the ideas.
