This track signal booster sounds good, I would be very interested in more information on how this works. Back in 2007 or 2008 Dale was at my home and we hooked up some sort of electrical apparatus on my layout, I think it was something to do with TMCC operation.
That was way before Dale worked on the TMCC buffer, so I don't know what that device was.
The TMCC booster is designed to help large layouts that have a lot of capacitive coupling to earth ground. That high capacitance kills the amplitude of the TMCC carrier signal and causes signal reception issues. The buffer is a very low impedance 3:1 amplifier that can drive a lot more capacitance and still keep a reasonable signal amplitude. I think Dale started on this one sometime in 2015.
