Can the DAX TX stream level be controlled by different profiles?

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.

    John I have you in the log 138 times going back to 2005 with many of those being RTTY. I have never noticed a dirty signal from you ever. Maybe you have changed things or the harmonics were being created in the receiver. On this end I treat rtty as any other digital mode in that I use DIGU and keep the ALC meter out of the red. No part of the ALC scale hits into the red zone.

    Thanks for the comment, John. This was the very first time anybody had mentioned anything to me and I suppose the problem was on the RX end with my very loud signal. I was running full power at 1500W so that could have been the issue. I have never changed my setup so I think I'll not make any changes. Thanks, again.
