| Connection of your interface to your PC's sound
card should be a simple matter of connecting your interface RX out to sound card Line In and
TX In (mic) to sound card Line Out or Speaker sockets. You will probably need to adjust the input
/ output levels of your sound card via the PC's Audio Mixer window. It is not advised to use
the sound card's mic input unless you have a very low RX output level. |
When using your PC's sound card you should disable Windows Sounds in order to
prevent any Windows sound event from being transmitted with your JT6M signal.

 |
| If you listen around 14.070Mhz to PSK or RTTY
signals you will quite often hear a familiar Windows event sound where the operator has failed
to disable Windows sounds !! |
| By using a second sound card for WSJT (and other
digital modes), you can keep your normal Windows sound settings. See Ver.5.x.x. WSJT Console. |
| Dual Sound cards |
| With 2 sound cards on your PC you will need to set the Audio Devices you wish to use in WSJT Console. (for Ver.5.x.x users). If you are using Ver.4.x.x then enable Use Spectran for input and select the soundcard within Spectran's menu,
