uBitx 12 MHz Crystal Filter transformer terminations


William Londree
 

I am puzzling over the 12 MHz Crystal Filter terminations. On the schematic transformers T5 and T6 have terminals 5 and 6 showing as each connected to an "x" and the filter description says that the filter is terminated to a robust 50 ohms to give a 200 ohm match to the filter on both ends. I have been "eye balling" the circuit board with magnification but can not determine where the winding sees a 50 ohm impedance termination. Wonder what I am missing??
