Well, I slope coupled the input with a 1200pF cap and a 10k resistor and if go directly from that into a non-inverting x10 opamp circuit and then to the PIC, I can actually see a signal. As of yet, all I can get is noise on the A/D tho, so it may just be that I have to change the point at which I do the A/D operation in the software. I will be trying a combination of circuits with the slope coupler, amplifier, buffer, and sampling opamp circuitry.

Also, since I am running the chip so slow, I don't think the slew rate nor the ADCON2 register would be a problem.
