    Swap the order you're writing to the registers... U, H, then L.
    When the NCO module is enabled, the NCO1INCU and
    NCO1INCH registers should be written first, then the
    NCO1INCL register. Writing to the NCO1INCL register
    initiates the increment buffer registers to be loaded
    simultaneously on the second rising edge of the
    NCO_clk signal.

    The registers are readable and writable. The increment
    registers are double-buffered to allow value changes to
    be made without first disabling the NCO module.

    When the NCO module is disabled, the increment
    buffers are loaded immediately after a write to the
    increment registers.

    Thanks Tumbleweed! That did the trick. Reversed the order of the Send, removed the On-Off-On in the Receiver, get my correct output right out the gate.
