[Ham-Mac] Still trying to go digital (with SignaLink, iBook G4, Cocoamodem, iMic)

[Richard Cincotta]

Dick,

   I communicated with you awhile back, and was unable to get my 
Cocoamodem/iBook G4 setup to work (and I was too busy traveling to worry 
about it).  Well, I'm back.

   Here's my problem.  I need to use an iMic for my input soundcard, which 
is placed in between the SignaLink A/D converter, and my iBook G4 USB port.  
But, the audio cord hookup -- going from the SignaLink to the iMic -- does 
not seem to work.  If I jiggle the plug that's stuck into the iMic input 
jack (showing the microphone) I only momentarily see the gain indicator, 
oscilloscopic ovals or PSK waterfall on Cocoamodem's screen display.   I 
can't sustain that input, however -- no matter how I hold the plug that's 
stuck in the input side of the iMic it only goes on for a fraction of a 
second.

   I know there's the issue of SignaLink only using the tip of the stereo 
audio plug & ground to communicate. If that's the problem, what do I need to 
do?  I guess another possibility is that my iMic is malfunctioning.

Any help from you or your knowledgeable comrades would be appreciated,

Rich, KI4FW
