K3 and FLDIGI Question

I’ve been using cocoaModem on my iMac for PSK31 QSO’s. Also, I use WSJT-X for JT65 and JT9. Recently downloaded FLDIGI v 3.22.01 and gave it a try. It works, but…..

When I transmit, I get absolutely no indication of RF being sent. The K3 goes into transmit mode, but I get no ALC action on the K3 meter. I know I’m getting RF out because (1) my KPA500 (in standby mode) is showing 30 watts, and (2) I’ve had several QSO’s on PSK31. If I bring up cocoaModem and transmit, I get the ALC action that I’m used to seeing: the fifth bar flickering. Same thing with WSJT-X. But for some reason, when I transmit with FLDIGI - nada, zip, zero indication.

Is this “normal”? If so, how would one ever set audio levels w/o having any indication of audio actually flowing? What do I have set wrong?

Thanks, Jim / W6JHB

Re: K3 and FLDIGI Question

Its not normal verify that you have the correct sound card selected in
FLdigi and that the levels are set correctly.

In the setup under configure sound card first tab
"devices" I have port audio set to the sound card for the rig
(soundblaster in my case)
under "settings" sample rate is native and converter is medium
interpolation. and corrections all 0 and
third tab "right channel" all buttons are clear unchecked.

Re: K3 and FLDIGI Question

Hi david - thanks for the reply to my post.

Unfortunately, no improvement. I have everything set exactly as you suggest (it was already that way) and the result is the same. I type in some text, press T/R and: the K3 goes into transmit mode, RF flows out the radio to the antenna, but no ALC indication on the K3 ALC meter. I shut down FLDIGI, bring up cocoaModem and do EXACTLY the same thing with absolutely no changes, and I get the RF out, but with the fifth ALC bar flickering. Funky, huh?

Re: K3 and FLDIGI Question

The same thing happens in my setup, if the audio level from the sound
card to the K3 is too low. Nothing will appear in the ALC window, no
matter how high I turn up the mic gain. Once establishing a minimum
audio level, the ALC will show four bars with the fifth flickering at a
mic level of 7. It's very touchy for me to get just right, but I am
probably using sub-optimal sound cards. Works fine, though, for all the
digital modes.

Re: K3 and FLDIGI Question

John - thanks - that hit the nail on the head for me. The setting I had on my external audio card’s output control was sufficient given the K3’s Mic level that I was using with cocoaModem and WSJT-X. However, as you pointed out, it was not sufficient enough for FLDIGI to “tickle” the K3. So - I increased the audio card output a bit until I saw the K3’s ALC bars light up, then backed down on the K3’s Mic gain. Now it’s working just fine with FLDIGI, cocoaModem, and WSJT-X.

Much appreciated for the replies from both of you - case closed!

Re: K3 and FLDIGI Question

Be Carfull you really should have four bars and fifth blinking if its
below that you can get some strange fluctuations on the output power.
so a compromise between programs is not the best idea. When the K3 is in
DATA A mode the mic gain will adjust the level for the line in so
adjustment when using different programs is easy.

level differences can be a problem with running multiple programs
for digital as they seems to have different algorithms and different
output levels I no longer use FLdigi and have moved to MMVARI as it
has internal TX level adjustment that is independent of the soundcard
level. with this I can match the output with the WSJT-X and
MMSSTV. I can't seem to find this independent control for FLdigi.
I have only tried Coacomodem some time ago but I believe it too has an
independent level control that may help in matching levels with other
programs although I cant remember if that setting is linked to the
windows levels or not
I don't believe that WSJT-X has this though.

Re: K3 and FLDIGI Question

Fldigi has a TX level *attenuator* control on the status bar (to the left
of the AFC button) that can be used to trim the TX level. It can be used
to adjust levels downward to match those of other programs. It's not
labeled and is often overlooked.

The K3 *can not* adjust transmit level (power output) by reducing audio
drive. If you reduce drive below the ALC threshold, power output will
become unstable and "drift". Set your sound card output to a fixed
level (typically 60 to 80% of maximum), adjust the K3 Line IN control
for four to five bars of ALC, then adjust desired power output using
the K3 PWR control.

Any other procedure risks unstable power output (low end) or significant
distortion (high end).

Re: K3 and FLDIGI Question

Hi Joe

I think what you say is understood. but there is a reason to adjust
what FLdigi calls TX level. This is to match the output level so it
matches other programs this adjustment is independent so it wont effect
levels from other programs. If the output levels of all program can
matched ie FLdigi WSJT-X, MMsstv, etc. it simplifies things when
moving from one digital program to another by not having to readjust
levels every time to achieve the proper setting of four bars fifth
blinking. I think if you read the rest of the postings you will
understand this need.

At least in the Windows world (Vista, Windows 7, Windows 8/8.1) that
adjustment is handled in the Windows Sound Mixer. The "Master"
control (hardware) for the output is set to 60 to 80%, the application
specific outputs are maintained as separate sub-mixer levels and are
generally left at 100% - 100% of the maximum set in the hardware -
since application based controls are all relative in the hardware
abstraction layer *unless* the particular application is designed to
use the sound card in "*exclusive* modes ("Port Audio" is not
exclusive).

In any case, reducing the audio output of a Windows based digital
application to control power output *will* run afoul of the ALC/power
control in the K3 (and presumably the KX3). The "attenuator" in
Fldigi (and any other digital software) should be left at 100% and
the audio drive controlled by the K3 Line In control.

Re: K3 and FLDIGI Question

In reply to this post by Joe Subich, W4TV-4

Sigh. I don't see how you read that into my message. I am *not*
advocating using the Fldigi attenuator to adjust transmit level in the
K3. That ofcourse is done with the K3 power setting, with the K3 input
control set for 4-5 bars ALC indicated.

I'm saying only that the attenuator can be used to establish
the level from flidigi to the soundcard, e.g. to equalize it (if
possible) with the output of other programs so that the soundcard and K3
settings don't have to be touched when switching between them.

Joe Subich, W4TV-4

Re: K3 and FLDIGI Question

I'm saying with a properly configured Windows system, there should be
no need to adjust the "TX Attenuator" in Fldigi and doing so can only
cause instability.

As long as each digital program is set for maximum level (maximum
digital gain) and the Windows Mixer control for that program is at the
same level as the hardware output level for that card, each program
will generate the same maximum output level. In this condition,
reducing the "TX Attenuator" in fldigi (or "digital output level" in
MMTTY, MMVARI, etc.) can only reduce the audio level for that program
and cause under drive with the attendant power instability in the K3.

Re: K3 and FLDIGI Question

I'm running fldigi on Linux.

You still seem to think I am advocating that the fldigi attenuator be
varied during operation, after the K3 mic control was adjusted for the
correct ALC indication, as a sort of power control. Of course that's
wrong. But again, that's not what I said!

I refer to the attenuator merely as an option to set the baseline fldigi
output level. This would be a static setting, made in the program
setup phase, with no need to touch it again.

Rest assured, there are 4-5 bars ALC at all times on my K3 during
digital operation, and if I want to change the power level I use the power
control!
