Setting up FLDIGI on K3s

Can someone provide detailed set up parameters to get the K3s to work with
FLDIGI? I've downloaded the most recent software and can't get the program
to work (e.g., although the "tx" light turns red when I "tune" FLDIGI,
there's no power output from the rig). Otherwise, the program tracks the
frequency of the rig, etc.

Thanks,

Mark, W9MS

Re: Setting up FLDIGI on K3s

Mark,

If you are using PTT from FLDIGI, that alone will cause the TX LED to
turn on.

I assume you are using the CODEC in the K3S - if so, do you have
anything plugged into the K3S LINE IN jack? That alone could be the
problem - LINE IN overrides the line out audio from the CODEC.

If the LINE IN jack is empty, then put the K3S into TX TEST mode (or
connect a dummy load) so you do not emit any RF on the air. Check the
MIC SEL menu to make sure it is set to LINE when if DATA A mode.

Then set the soundcard LINE OUT level to about 75% in the computer.
Put FLDIGI into transmit and adjust the Line In gain (MIC GAIN) to
achieve 4 bars solid on the ALC meter with the 5th bar flashing. That
is the proper audio level for soundcard digital modes - leave it set there.

Go back to normal transmit and see if you have RF. Adjust the POWER
knob for your desired power level.

Ignore the info in the FLDIGI instructions which say to set the power at
maximum and control the power level with the audio level. That is for
other transceivers - for the K3/K3S, follow the instructions in the
K3/K3S manual.

I am running into the exact same thing. fldigi gets audio and freq from rig
no problem. USB codec selected for fldigi output but rig just shows TX light
but no power out or ALC indication on rig. Nothing plugged into line in
jack. Rig set to TX DATA. MIC SEL = Line in on rig. Same symptoms with
FreeDV and WSJTx...

USB audio and rig control fine and PPT works but no rig sound card going
out.

anyone else find this and solved it?

Thanks,

Brian ve3bwp

Re: Setting up FLDIGI on K3s

Solved it.

In TX DATA mode the MIC level controls the LINE IN Level (dah!). So add
that to your checklist!

Mine was at the default 0. Turned it up and level 5 seems to be the right
amount of drive.

Thanks all.

I hope someone has solved this, too, as I am having the identical problem with my KX3. Other digital modes like FT8 work FB. I would like to not have to use VOX to key the rig. I suspect that I just haven't found the right combination of trial & error.

Re: Setting up FLDIGI on K3s

Within FLDIGI there is a transmit audio level control in the lower right
corner.    Just below the LK tab.   I use a value of -15. The arrows
left and right of the box will increase or decrease the level going to
the radio.      My Line Gain which is adjusted by using the MIC knob is
at 30.

There are 3 places where the transmit audio level should be adjusted.

(a)   The computer SPKR level.   {mine is 30%}

(b)   The application transmit audio level   {mine is -15}

(c)   The radio Line Gain level {mine is 30}

Ideally, they should never be at a maximum or near minimum value but
more near "mid range". I call that between 30 and 50 what ever units
that may be. This will prevent overdrive and distortion of a stage
or circuit. And these should supply adequate level to the radio to
produce 4 solid bars showing on the ALC scale.   With Elecraft radios,
always set the transmit power output with the PWR control on the radio
and NEVER with the audio level.    Also be advised that often when one
runs another application previously on the computer, the SPKR level many
change due to the needs or a previously used value.    Just the way some
things work.   Always check the values to prevent frustration, bad
signals and "nothing works" conditions.

To those having problems with DATA modes, take a look at the article on
my website www.w3fpr.com. Scroll the left column to the last article
and click on it to open the document.

While VOX should reliably put the radio into transmit, you can set
FLDIGI to use PTT via CAT command - BUT don't use both.

Download and install FLRig. Setup is straight forward and they support K3 (and maybe KX3 but since they're all the same command language, K3 should work). FLRig implements CAT control eliminating the need to use VOX. HTH
