[TenTec] TenTec Digest, Vol 156, Issue 4

I'm not sure that's the right question to ask because recovery doesn't
necessarily happen in real time.  The Flex T/R cw recovery is really a mind
blower for an SDR.  But does it necessarily mean you can do actual QSK and
hear someone else trying to break you in real time?  I think there's still
receive latency so that even with the receiver recovering, it still lags
real time signals by 150msec (or whatever).
