The audio output of the receiver is fed into a laptop PC via a Logitech USB headset whose headset has been cut off and replaced by sockets, so that the USB audio ADC can be used to feed good quality audio into the laptop.
There is therefore no squarewave output from the AD on-chip comparator. The description below may help people who need to adjust an AD module for use in an Ultimate3 kit.
