No Waterfall Display in FLDIGI when KX3 is in DATA mode

[Steve Watkins]

I recently connected my KX3 with a Signaling  USB interface and using FLDIGI on my Macbook Pro.

I was NOT receiving any signals on the waterfall display when I was in the DATA mode recommended in the KX3 Owners Manual.  However, I was able to receive signals if I switched to USB.

I was able to transmit and control the ALC to 4-5 bars with the Signalink  only if I was in USB but it didn’t have any affect if in DATA mode .

Two questions:

1.  Is there something obvious in my settings (maybe in FLDIGI ?) that allows me to receive nice signals on the waterfall in USB mode but not in the KX3’s data mode?

2. Is it (OK) to communicate in PSK31 mode with the KX3 in USB as long as my transmit ALC is kept to 3-5 bars?


Any suggestions would be much appreciated, as I’m tearing my hair out (what’s left of it)

Steve,

Is there any chance that you have not turned the Compression to zero in
USB mode?
That would give you more bars on the ALC meter when in USB mode as
compared to DATA A.
Are you certain the DATA submode is set to DATA A?

The receive path (signals on the waterfall display) is a function of the
KX3 audio gain setting and the soundcard input setting.  Be certain the
computer soundcard is set to LINE IN and the volume slider is set
between mid-way and 2/3 of maximum.

That is quite different than the transmit path which is from your
soundcard output - again set the slider for your soundcard output to
about 2/3 of maximum and try again for 4 to 5 bars on the ALC meter when
in DATA A mode.

Steve,

In DATA A have you adjusted the bandwidth of the filter? It may be set too narrow. I can't think of any other reason why USB should work in RX and not DATA A.

You are in DATA A not some other DATA mode? Again that would explain why you are not getting any output in transmit.
