I found that one of the uplink problems is that the beginning of the 
digital FSK stream may get clipped or malformed when the transmitter is 
keying up.  I'm using a Tigertronics SignaLink and this was a problem for 
me in the beginning.  If you don't have enough audio, it was slow to key 
up.  If you had too much, it would distort the waveform.

Tigertronics had a couple of modifications on their web site that made the 
key-up process more sensitive.  After I made that mod I didn't have the 
problem.
