I have checked out the SDRTX transmitter software and it is cool. I understand that you have to make sure that the QSE mixer audio band frequency response has to be good down on the low end for the bias carrier tone on AM and FM. (67Hz) I see you can also turn the bias tone off in the .ini file. It might be better to try and use this with your own contrived AM and FM carrier and not have a bias carrier tone if possible so as not to be heard by having the carrier set in the hardware. Which doesn't sound hard to do. It seems it would work, but it will take an experiment to prove. All in all though this is something nice to have. I found also the mentioned DG8SAQ SSB IQ Generator and it seems nice also. You can do some interesting test using your spectrum analyzer and oscilloscope softwares with this. You might have to first convert the audio output to a wave file and play it back so as not to take up allot of processing power to get the analysis software working smoothly. You can get some nice oscilloscope graphics from this for illustrations of 90 degrees phasing examples for your text and websites. There are quite a few nice circuit diagrams in the links in this topic so look for them
