Sounds like Ten-Tec used the same approach on the Orion as they have
with their other products here.... no SWR protection & instead current limiting
the finals.
This is really handy, as Earl noted, when on 1.8 Mc as most of us don't
enjoy much low SWR bandwidth on our antennas.
Further reports from Earl on receiver performance as compared to MP &
K2 are eagerly awaited!
