Not sure if this applies also to the SPM12, but I have used temporarily a Selective Voltmeter from W&G which had a last IF output at 10 kHz. You need a product detector, implemented either in hardware or software (at this frequency it is practical to do it) for SSB reception. Unless I am mistaken, the latest version of SpecLab from Wolf DL4YHF has an I/Q demodulator that could be used for this. 73 Alberto I2PHD
