Hi Glen and all, There's something I don't understand here: In the SM1000 we have control of all the amplitudes AND phases of all the audio carriers. Thus we may be able to do something to reduce the peak levels that an IDEAL SSB generator will produce.
This is where I have a problem, the majority of SSB transceivers do not have an ideal SSB generator. In particular, we loose the phase consistancy. Am I correct?
