I would like to control the DAX TX stream for different applications, such as RTTY when using an amp and RTTY when not using an amp. When using the amp I need to reduce the TX audio to about 38% and have the RF power output set for 100% in order for the amp to have the proper full output. I was told today that I was generating harmonics when transmitting and I believe the way to eliminate this is to have lower DAX TX output. Am I not correct in this idea? If I have the audio set for 38% when not using the amp my output is much lower than 100 watts that I would desire.
