I have a question about the interaction between the RF Power slider and the TX Gain slider, especially for the digital modes using DIGU and RTTY. Running a 6300 with the latest SSDR.
I want to avoid overdriving anything which would produce splatter or other IMD products.
Let's say I want 25 watts of RF out using JT65 mode. I see two ways to accomplish this:
1. Set the RF Power slider to 25 watts and the TX Gain slider to something around there or higher.
2. Set the RF Power slider to something above 25 watts and use the TX Gain slider to limit the power to 25 watts.
Either way will give me 25 watts of RF output, but is one preferable over the other? I suspect it would be #2 but I want to hear from the experts.
And finally, is DIGU different from RTTY in this respect?
Many thanks for your help and advice.
