the low-latency required for this type of keying. This low-latency
stuff is responsible for quite some hiccups on the software side.
A better thing would be to FORGET the shaping and key the tx
directly, I and Q signals always on. The rx soundcard could be active
while transmitting, allowing to listen in between the dits. I think
this would work much better than to route those signals trough a PC
with a lame non-realtime OS.
