The mailing list doesn't have QSK capability.

My understanding of the subject is, the transceiver won't send RF until it
knows the amp is ready for it as a means to prevent clipped dits and
fouled relay contacts.  A nice QSK amp like the Centurion or Titan will
give you full receive between dits so theoretically you should not notice
the difference between with and without the amp running.  There is a
reason Ten-Tec makes mention of the specific type and brand of relay in
the Centurion - you're talking about a LOT of relay operation over time -
got to be a stout relay to stand up to it.
