Unless I'm mistaken, always a possibility, the Line Out doesn't have the benefit of the new LP filter, if you have that option. So you still get the full IMD and digital artifacts.

The K3 has a fixed level (pre-fader level for audio pros) output. Use the "Line Out" set to "nor" and set the level as appropriate for your external hardware. I have not checked recently with a calibrated audio voltmeter, but I do recall easily seeing .775V RMS with a 50 uV signal and AGC off - I even had to reduce the RF gain to keep from distorting (exceeding 1V+ RMS - note the DAC output can go to about 4.2V P-P and with transformer loss the actual output should easily reach 2V P-P or .775mV RMS). The only question is adding monitor and sidetone audio to that "Line Out" audio ... and I don't see a digital mixer capable of providing that capability unless it can be coded into the overall DSP. The real question though is, if you are going to all the trouble to use a leveller, mixer, headset amplifier and speaker chain, why would you even attempt to adjust the audio on the transceiver? Doing so is like giving an intern, production assistant, or news videographer a "greenie" and leaving them alone with the equipment <G>. 73, ...
