Sounds like you're de-emphasizing the RX audio and not pre-emphasizing
the TA audio, but should be.
The exact set-up is determined by the radio and what it wants/needs.
What radio are you using and how do you have it connected? What radio
adapter are you using?

It was too much, loosing too many of the higher frequency components that make for clarity of audio. I'm looking for information on what settings (e.g. dsp, and the rx and tx settings, =flat, =speaker, etc) that have a pre- or de-emphasis effects in app_rpt. A general discussion would be useful as well. I can address this in hardware, but wanted to explore the software approach first.
