[Elecraft] Low tone audio Tx

[Walter Underwood]

To get pictures of that recommendation, see this blog post. I collected a dozen sets of transmit equalization settings from this list and K9YC’s settings were representative of the consensus.

The process for the KX3 uses the digital voice recorder and A/B comparison by ear. In the KX3, the DVR is after equalization and compression in the transmit audio chain. Someone with detailed knowledge of the K3 would have to say whether that also works for that rig.

NOW, turn up COMP, set the display meter to read Comp, and while to talk like you would on the air, increase COMP until you see about 10 dB of COMP on the meter on voice peaks.

Tell them you DON'T want "warmth" or "fullness," you want a signal that will cut through QRM an noise, but still sound pleasant. Depending on your mic and your voice, you may want to use more or less cut of the 4th band, and a little more boost of the top two. Don't go higher than 6 dB.
