CW sideband

Amen to all the above, brother!
It's the second thing that makes me crazy about the K3.
I think it of as 'Icom user' vs 'Yaesu user' (I'm the latter).
I guess I developed the habit with my first single-signal radio
(a 75A-4 on 20-10 meters in 1958 where the SSB was Upper).
I prefer to change bands from the radio, with software following (and I
also use Logger32).

Now just a doggone minute - I'm certainly north of the equator!

>do ...toilet swirlies really run counterclockwise down there?
When I've got my head in the toilet, I'm generally not in a mood to check
the direction the water is going :-)

ps: the first thing that drives me crazy about the K3?
The fact that the radio (and the amp) key when I'm playing with my paddles
and just wanna hear my own CW.

Me too.

I guess it must be done this way for people who send the key first to
their amp or antenna switch, and then get their PTT back to the radio
from it? Like from an extra contact pair on a relay that bypasses a
mast-mount preamp. People hate smoking those.

I also would like to be able to turn it off, so that Key Out occurs
only when VOX or PTT is already asserted. Yet another menu option for
the bottom of the software wish list!

Also, I'm away from my K3 now but I could swear that it works at full
QSK even if you don't have QSK enabled. That's pretty odd.

73 and thanks for listening,

Re: Key out (was CW sideband)

If you don't want power output when you hit the key, turn off the VOX while
in CW mode - the rig responds with "PTT" in the message area. To get power
out with VOX off, you must press the XMIT button or active the PTT (with a
footswitch, for example) while keying the paddles.

Depending on what you mean, this is also the answer to the "full QSK"
statement. VOX "on" means that pressing the key activates the transmitter.
QSK on means the RX is active between code elements. Here is the "truth
table" for VOX and QSK:

VOX QSK
Off (message = PTT) Off (message = SEMI) XMIT button or PTT to
transmit
Off On (message = FULL) Same as Off - Off
On (message = VOX) Off Key = transmit;
no RX between elements
On On Key =
transmit; RX between elements

Re: Key out (was CW sideband)

That isn't the problem. Even if you have VOX off, hitting the paddles
activates the T/R relay line to the amplifier. It does so even if you
put the K3 into TEST mode. There's no power output, but the amp relay
(and anything else that may be activated by PTT) engages.

It is Key Out - not amplifier PTT. The difference is subtle but
simple. However, if you don't want your amplifier keyed, put
the amp in standby.

That's right - it does. Again, the signal is "Key Out" not
"Amplifier PTT." Key out should ALWAYS follow the straight
key (or internal keyer) input regardless of whether the K3
is producing power.

Actually, it follows the logical OR of XMIT button and key.
