You can try a bipolar, but you might have some residual leakage which will
show up as a low-amplitude distorted (clipped) waveform. I'm trying to
remember what option card(s) used that P701 to kill the PL encode so I could
look at the schematic to see what they're keying it with, but I can't
remember. Maybe Eric knows off the top of his head?
