use the "9600" out. As far as I know, the ISS uses 1200 baud.<BR><BR>I'm
not sure that I understand. With your D700 you adjust the frequency to
compensate for the doppler effect and you can decode packets. Your
system at home, where you don't adjust the frequency to compensate for the
dopple effect, you can't decode packets. <BR><BR>When you ask about the
performance of AGWPE, I assume your talking about the soundcard TNC feature,
just one small part of what AGWPE does. The most important part is that
your audio levels are correct and that no ground loops exist. This means
that the computer, the radio and soundcard interface all share a common
ground. <BR><BR>Laptops usually have a microphone input and a headphone
output, but not a line-in. I have learned from exerience that sometimes,
even when you manually set the audio levels, the microphone input tries to
automatically compensate for loud sounds. This "ALC" usually can't be
disabled. You might try a desktop computer with a line level input or
get an external soundblaster for the laptop. <BR></BLOCKQUOTE></BODY></HTML>
