Transmit audio monitor level control

[Augie "Gus" Hansen]

I didn't see anything in the K3 FAQ regarding the way CW sidetone and
phone transmit audio monitor levels are controlled. Some rigs allow
setting a monitor level that is independent of the receive audio level.
Others allow setting a base monitor level that is then altered by the
receive audio level setting.

Each method has benefits and drawbacks, but I prefer being able to set
TX monitor levels independently to avoid accidentally blasting my ears
in the headphones. Which method is used in the K3? Or is this a
configurable option like almost everything else on the K3?

Push and hold "MON".  Then adjust it.  If you are in SSB, it'll adjust
your SSB monitor volume.  If you are in CW, it'll adjust your sidetone
level.  The radio remembers your selection until you change it.

Gus,

Of the four knobs to the left of the main tuning knob, the lower right one
has a HOLD function of MON (Monitor).  This adjusts both the sidetone level
and monitor level in other modes.

Hi Greg,

Thanks to both you and Lyle for the timely responses.

I had assumed there is a way to set the desired monitoring levels and I
appreciate the description of the means by which this is done. However,
there is still a question about the effect of changes to the receive
audio levels (AF and SUB) on those monitor levels. If the K3 is like the
K2, there will be no effect, which is what I hope will be the case. I
don't want the TX monitor level to change when I adjust RX audio levels.

Examples of rigs that do alter the TX monitor level when the RX audio
level is changed are all of the Icom transceivers that I have owned.
They inject the TX monitor into the audio stream before the AF gain
control circuit and treat that control as a "master" level control for
both RX and TX. On the other hand, my Yaesu FT-1000mp injects the TX
monitor signal into the audio chain on its own input, separate from the
RX audio, as in a mixer with individual level controls. That way, I can
crank the RX audio way up to hear the weak ones and not blow out my
eardrums with monitor audio when I transmit. Much safer in my view.

Cheers,
Gus Hansen

The monitor levels are independent of and not changed by the main and
sub volume controls.

Thanks Eric,

That's "music to my ears," so to speak.
