T1 vs KAT2

[Dick Wiltgen]

I have been trying to seek information about the relative merits of using  
the T1 vs the KAT2 antenna tuners with the K2.  For some reason, my request  has
apparently not been posted. There has only been one review of the KAT2 on  
eham.  There have been many on the T1, but most pertain to the  FT-817.  Has
anyone had experience with both tuners with the K@ and is  willing to share their
experience with me. TU

Dick ...

I can give you a partially complete answer.  I have a K2 with the internal
tuner and am very pleased with it.  I also just bought (but have not yet
built) a T1 tuner.

>From what I can piece together from the specs on the Elecraft website, the
T1 tuner will provide essentially the same power handling capability and
impedance matching range as the internal K2 tuner.  Both of these are
superior to the range and power handling of the internal tuners in the KX-1
and K1.

The reason I also bought the T1 is that for my station I think locating the
tuner remotely at the base of my vertical array could be advantageous.  I
also want to experiment with using it for portable work with the tuner right
at the antenna for my Buddipole.  For these applications, I believe it will
be superior to the internal K2 tuner.  The downside is that it is not as
integrated as the internal K2 tuner and will not provide as much useful info
on the K2 display.  It will also require a remote cable connection to
initiate the tuning function rather than the automatic implementation with
the K2 internal tuner.

So your choice may well depend upon your application, antennas and desired
type of operation.  You may indeed end up with both as I did  ;>)

Dick,

As Craig mentioned, the KAT2 has the advantage of being very well
integrated with the K2. It also has dual antenna jacks (controlled via
the K2's ANT1/2 switch), a wider matching range, and its settings will
be instantly updated when you change bands on the K2. It stores the
most recent L-C settings for both antennas on all bands in EEPROM so
the settings will still be there when you turn on power. Most
important, though, it provides the K2 with a true SWR bridge. The K2
itself has a composite forward power indication, but the bridge in the
KAT2 provides much more accurate power setting, not to mention SWR
info, when working into non-resonant loads.

Above all, you'll find that the KAT2 is convenient. It's installed
inside the rig, and when you combine that with the internal battery,
you have either the world's most efficient and high-performance
emergency station, or the world's largest HF HT  :)

On the other hand, we designed the T1 to work well with the K2 *and*
every other QRP rig on the planet. So if you have other QRP rigs, you
may prefer the T1.
