@gunrunnerjohn posted:I'd stick with the Deats filter values, 47 ohm is a little stiff for the DCS signal, you may end up doing more damage than good by attenuating the signal. The 220 ohm resistor specified on the page below is plenty of load to tame the signal reflections.

Actually, I did both. I went with the 100-Ohm first and it worked well, but it worked just as well with the 220.
