Unwanted audio

[Martin]

Elecrafters,
my K3 shows a strange Problem. On USB it transmits a tone at about 2khz
above (respectively on LSB about 2khz below) carrierpoint. This happens
even with no mic attached. The level of the tone follows the setting of
the 2.4khz level of TXEQ. It also follows Mic Gain level.
Anyone know what to do?
Setup: Dynamic Mic on Frontpanel (or removed, doesn't matter), tap XMIT,
listen on sdr-console.

Nice try,
but no, 2 TONE is OFF . I should've said that.

As a workaround I reduced Mic Gain a little, switched on TX Gate and set
it to a level the tone wouldn't trigger TX Gate. Now it is not audible
anymore when i don't speak, but comes on again as i trigger TX Gate with
my voice.
It is not very loud, but the otherwise beautiful audio is 'unaesthetic'.

Thank you.

Martin,

Just a thought - do you have anything plugged into the LINE IN jack?  Or
do you have MIC plus LINE set on?
Another thought - do you have the FP mic set to turn on the additional
mic preamp?
