[K3S] Audio from computer speakers with RSP1A connected to P3 IF Out

[N7US]

I recently bought a SDRplay RSP1A SDR and have it connected to the IF Out on
my P3, and I'm using it with Win4K3Suite for a spectrum display.

 

When the radio is tuned to a quiet frequency on CW, I hear weak CW through
my computer speakers, but it stops if I unplug the RSP1A from the P3's IF
Out jack.   (I assume the same would happen on other modes.)

 

The volume is faint, and I can adjust it speakers' volume control or the
computer's speaker volume (in Windows) on my keyboard.  I can tune the
signal in by changing the VFO frequency on the K3S, but I hear the signal a
couple kHz above zero beat, so it's very broad.

 

Does this make any sense?  Thanks for any insight.

Dear Brain-Trust,
        I currently use RUMLog and/or SkookumLogger for my contest work (K3S and a Mac)….

        I recently tried to work the RTTY Contest, but found the FLDIGI interface not very smooth, could not get the integration with RUMLog working, and then found that COCOA-Modem is out of compile life….

        So …. Suggestions please ?? All acceptable except ditching the Mac.

        Regards
