[Elecraft] Adjusting Audio Level for Digital Modes

2017-09-08 Thread Bob McGraw K4TAX
Don is absolutely correct on his earlier points.   The K3S setup and operation does not follow the suggestions for setting the audio levels as other radios and as described in the WSJT-X user information. In DATA mode, it is my view that A L C stands for AUDIO  LEVEL CREST.  i.e. the highest p

Bob and all, Lyle Johnson (the DSP designer) has stated several times that actual ALC begins at the 5th bar on the "ALC" meter. That is the point of "Zero ALC" for the K3/K3S/KX3/KX2. The K2 is different in its indication in that the ALC begins at the 1st bar illuminated. The data mode set

At present, I have my PC's USB Audio Codec Playback Level set at 35%, and am adjusting ALC with the MIC knob. With the WSTJ-X Tune ON, I'm slowly increasing MIC until the 3rd bar shows. Further increase jumps directly to the 5th bar, with no 4th bar appearing or flashing 5th bar. I could swear I us

Bret, You likely have the LINE IN level in the K3/K3S set to either the high or low end of the range. Set it first for midrange (about 30), and then set the soundcard "speaker" output slider for about 50%, and set the WSJT-X slider also to about 50%. Then see what the ALC meter reads during

As an operational note for WSJT-X.  Version 1.8.0 -rc2 To adjust the audio level via the software slider marked *Pwr* on the right, I find it more precise to place the cursor just above or just below the slider bar, depending which way you wish the audio level to go, and click the left mouse b

How about using the mouse scroll wheel, it adjusts the power in 0.1dB steps. At least it does on my Win7 box. The waterfall sliders also respond to the scroll wheel. Regards, Mike VP8NO On 08/09/2017 21:52, Bob McGraw K4TAX wrote: As an operational note for WSJT-X.  Version 1.8.0 -rc2 To ad

My testing with WSJT-X (FT8) "tune" for an audio tone, says that any ALC indication at all, no matter where it is, gives exactly the same RF output.  That said, _and this may only apply to my situation, _the signal is cleaner with only three bars lit. I'm seeing 52 Hz spurs at -50 dBc for anythi

That seemed to do the trick Don. Edging the WSJT-X Power Slider down to mid-scale and K3S MIC LINE IN to ~30 gave me the wiggle room to get the 5th bar flashing. In fact, flashing just a bit was less effective than flashing a lot, but still short of solid 5th bar ON. But I guess the 5th bar flash

Thanks Bret, glad you found success. This note is information to all who are using any soundcard digital modes. This is a situation of having too many controls that do the same thing (adjust the audio level). There are 2 in the computer - soundcard "speaker" level and the WSJT-X "power level".
