My apologies to all. Some of what I said about PSK is not 100% correct, although the answer to the originally posted question remains the same. You cannot operate PSK by connecting anything to the FSK jack on an Omni VI. PSK31 uses two phases of a single tone. The two phases are 180 degrees relative to each other. Only QPSK uses 90 degree phases. In either case amplitude variations are essential for getting the data across. The FSK input on an Omni VI selects between two frequencies adjusted by two trimmer capacitors in the BFO crystal oscillator.
