assigned them to PF1 and PF2 on the KX3. I only have the two macros and

Hi Terry,

the rig into data mode (from the Radio tab - MODE = NONE). I don't remember
the power settings by band on the Audio tab within the settings dialogue. I

I said earlier:
"If I set the tone to 1500 Hz, the FT8 mid-band target, I'm presented with the
cyclic ALC and some ~193 Hz, -50 dBc sidebands. "
Ten KHz/div is too coarse to see these. Try again.

Here are some spectrum photos from the tune signals of both FLDIGI and
WSJT-X 1.8. All three are essentially identical showing some low level
sideband noise +/- 30 kHz and down > 60dBc. There's no apparent
difference in the spectra between pumping and non-pumping ALC, as Wes
reported.

Except when the sound card is in the computer instead of the radio, "Line In" is
receiving signal from the program via the sound card 'speaker' output, not the
microphone. Moving the card into the radio doesn't change this. The only thing
changed is it's too darned sensitive.

Wayne,
There are no beat notes. These frequencies, at least from the FT8 program in
Tune mode are single frequency. Based upon output RF spectrum measurements*,
with for example 1010 Hz input and 4-5 bars of ALC, I see spurious or
intermodulation sidebands, down -65 dBc. If I change nothing
The "TUNE" tones from both applications (FLDIGI & WSJT-X) looks like a single
frequency and is a pretty decent sine wave on the scope, although "pretty

beating with some process within the K3. The "pulsing " isn't appar
Is it possible that a beat note between tones (and their harmonics) is what’s
modulating the ALC reading? If so, moving the tone slightly off the standard
pitch may be an acceptable workaround.

A blast from the past, it's been 17 years since I was involved with this

In E1 PCM multi channel voice transmission systems the standard test

This is not a fault but a fact of life.

Hi,
I’ve seen the same behavior when running digital modes on my KX3. It seems like
maybe it does that (dropping to zero) when overdriven? Just a guess.

Those settings are too extreme - they need to be more mid-range.
Set the K3 LINE IN gain to something mid-range (about 30), then reduce

I have exactly the same problem. For me it does not occur with RTTY. That

Dave,
Set the K3 LINE IN gain for a midrange value. It has more resolution
there than at either a high or a low setting.
Then adjust the soundcard to obtain about 4 bars on the ALC meter and
"fine tune" that level with the LINE IN gain to get the 5th bar to flicker.

I have plenty of audio, and can drive the ALC to 6 or more bars if I
