PSK 31 HELP!!

[W5KAP]

I used to be able to do PSK 31 on my TS-2000 until I tried to use a laptop and a Rig Blaster plus I bought at Dayton in 2005.  I also recently purchased the DB9 to USB cable to make life easier.  My problem must be in the computer.  I can hear the signal nice and loud but on all my different software packages, the signal fades in and out so I never get a strong steady signal.  I realize I need to make the audio input on the laptop work was the input vice the mic but even with a direct audio hook up, I get the same intermittent signal displayed on the waterfall.  I am stumped.  Any of you experts want to weigh in on this.

Cheers, and 73 de Kenn W5KAP

Make sure Auto Notch and Noise Reduction are off. Turn down your RF Gain and turn off AGC, then bring it up with RF Gain. Still choppy?

  Is the computer using the microphone or has the line/USB been selected in the "Sound card" settings.

  I used Prolific USB/Serial cables until recently.  They don't work with the newer Windows or OSX.    I'm using a FTDI chip Serial cable and it's working.

You know, that's a good question.  I have it set up so that the audio comes to the mic input from the TS-2000.  My USB cable is to control transmit with  the radio via the USB Cable.  I didn't know I could select a USB input on the sound card.  I'll have to check that out.  Right now I gave up on it as it was frustrating me!!  For what it's worth I am using windows 7 on a Toshiba Satellite a couple of years old.  Thanks for thinking of a solution.
