[Elecraft] K3: Recording from LIN OUT

[Wes Stewart]

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>.
