I  don't think any hardware TU these days is the ultimate TU, because
DSP  modems implemented in the computer can be a lot smarter.

Some people  consider the ST-8000 to be the ultimate hardware TU, and
at least one guy  even claimed it outperforms a software modem, but I
think he had some hard  feelings toward the author of the software.

The Dovetron gets mixed  reviews.  I pointed out some time back that
there is a construction  error in certain of the Dovetron units that
causes performance to be worse  than it should be.

Then main argument concerns performance in the  presence of multipath
echoes.  Dovetron had several circuits that were  supposed to help with
that, but seemed to eventually have given up on  them.  The ST-8000 has
what seems like a reasonable approach to the  problem, but I don't know
how well it works in practice.  I'm having  some discussions with the
author of a software modem on that same  topic.
