It would be especially applicable to those of us with nonlinear LF transmitters (class C, D, E) wishing to run sound card based modes (and even SSB). I'm especially interested to know about any sound card to LF carrier and amplitude exciter designs or converters, or I and Q converters. 73, Murray ZL1BPU
