Chris.
I have my TX and RX set at 9 o'clock " each rig is different" I set to low
power and get my signal looking good and then increase my power on the K2
to my 25 watts desired power. On my radio anything over 25 in digital mode
causes distortion. Works fine on CW and SSB. But other digital modes
I've been playing with this for the the last few hours.
It's possible to reduce the input level to get the 10-th ALC bar to
disappear and, apparently, provide too little signal to the RF amp. It
seems a little sensitive on the SignalLink Tx gain control.
Given that I'm at the low end of the ga
Another minor issue is that the audio drive will vary somewhat depending on
which audio frequency is selected. i.e. 600 hertz vs 1800 Hz. will not exhibit
the same energy to the radio. Soundcards are not flat, many rigs are not
either.
So if you set levels for one (if RTTY, pair of) frequenc
Yes, the K2 transmit gain can change with the various bands. There is
some level of TX RF gain compensation in the K2 circuits, but it is not
perfect.
Because of the way the K2 controls power, setting the power first and
then bringing up the audio to produce that power output is a bit
"iffy"

YES! Several times I've published a simple procedure for setting
computer sound card levels. It goes like this.

Chris,
With your soundcard gains at maximum, it is possible that the output is
being overdriven and causing distortion (they are not "out of the
picture" at all.
I suggest you reduce the soundcard gain to the range of 1/2 to 2/3 of
full which will allow more range on the SignaLink gain.
73,
Good. If 9 o'clock and all is good then use Don's suggestion and set alc
and you should be fine.
Good luck.

Thanks for the comments.
I'm using Olivia/Contestia most of the time rather than MPSK. The possible
splatter is with the SignalLink gains at 9 o'clock, a near minimal setting.
Aside from the transmit gains, the system is operating normally, and the
sound card is clearly recognized and in use.
Thanks, Don!
I never knew quite what the ALC was for. Good point about the RTTY filter
set, too.

Chris,
For data modes with the K2, there is an indication in the K2 itself that
should prevent splattering. That is the ALC meter.
Turn the RF/ALC meter to read ALC, then adjust your audio level until
you see the LED display blinking the 10th bar of the LED indicator -
then back off the gain
Chris, what mode are you trying and what do you have your power set to?
Also if your RX and TX on the Signalink are maxed, use the Signalink
internal jumper to boast the gain so you can turn them down. Also check the
computer volume both sound and microphone recording. And make sure the
computer is
Can't help you with the specific problem as I use a RigBlaster instead
