Just the SL's spectrum analyzer / waterfall to "Complex, separate I/Q-inputs" and ready you are. One could also modify John's exciter a bit to turn it into a RX+TX: http://www.w1tag.com/Phasing.htm (ok, it may be easier to add a second 74HC4066 for the RX side, than to flip the amplifiers, but the I/Q processing principle remains the same). If anyone needs additional info on how to configure SpecLab for this job, I will write step-by-step guide. It's simple once you know how ;-) Best regards, Wolf DL4YHF .
