@AmFlyer posted:In two rail, larger and more complex layouts work better with the Legacy signal on both rails. This is done with .1 microfarad 50V ceramic capacitors. They are tiny and inexpensive. Using these capacitors all segments of the rails can carry the Legacy signal, even the isolated sections where necessary for good Legacy signal reception. One caution, I do not have DCS so I do not know if these would degrade the DCS signal.
They would nuke the DCS signal, that would be a point of contention if you did have DCS! .1uf at 3.27mhz results in a capacitive reactance of around half an ohm. So, that would be like putting a 1/2 ohm resistor across the DCS signal output! Needless to say, the TIU DCS signal would be seriously impacted by multiple .1uf capacitors across the outputs!
