[amsat-bb] The signalink USB does not pass 9k6 audio bandwidth

Mike:

I can confirm that the Signalink will not pass 9600 baud signals out of 
the box. The tech at Tigertronics told me that some have modified the 
unit to work 9600 baud packet, but didn't have any further details. I 
suspect the mod has to do with bypassing the audio transformers.

Another approach would be to use your PC's sound card along with UZ7HO's 
full-duplex Soundmodem. I've had great success working Falconsat using 
this setup with a cheap StarTech USB sound card. Scott's, K4DKR, 
plug-n-play PTT works well with this setup.

If your intention is to work Falconsat, you'll need a virtual serial 
port to link Wisp with the UZ7HO's Soundmodem. Let me know if you need 
further details.
