1.4 TRANSCEIVER
INTERCONNECTIONS: When using the
TITAN III with TEN-TEC transceivers with
TX EN and TX OUT connectors, follow the
diagram in Figure 1-1. The QSK-PTT/VOX
switch on the TITAN III should be in the
QSK position for all modes of operation.
This hook-up arrangement will work with
the OMNI series, PARAGON I and II,
PEGASUS, JUPITER, and ORION. Some
modern Yaesu transceivers are also
equipped with a full break-in keying loop
that can be utilized in a similar fashion. If
you are unsure about connecting this
equipment, please contact the TEN-TEC
factory for instructions.
When connecting the TITAN III with all
other transceivers, use the diagram in Figure
1-2. Note that the key or keyer must be
connected to the KEY IN jack on the
TITAN III, a cable is run from KEY OUT
to the key input jack on your transceiver,
and the line from the external T/R N.O.
relay contacts on the transceiver must be
connected to the PTT/QSK jack on the
TITAN III. When using this configuration,
the QSK-PTT/VOX switch on the amplifier
must be in the PTT/VOX position for SSB
operation and in the QSK position for CW
operation.
1.5 ANTENNA REQUIREMENTS:
The TITAN III amplifier is designed for use
with antennas resonant at the frequency of
operation and having an impedance within
the limit of 25 to 100 ohms, or an SWR of
2:1 or less (<10% reflected power). Note
that any SWR other than 1:1 will result in
TUNE and LOAD settings different from
those in the manual reference chart (Figure
2-1). The nominal load impedance of the
amplifier is 50 ohms. Antennas can exhibit
an SWR of more than 2:1 in some part of the
band. For operation under these conditions,
we recommend using an antenna matching
network that will enable the TITAN III to
work into a 50 ohm load for maximum
power transfer to the antenna.
1.6 GROUND CONNECTION: In the
interest of personal safety and to reduce the
possibility of stray RF pickup on
interconnecting cables, all station equipment
should be well grounded to earth and to
supply line ground bus. It is important to
strap all equipment chassis together with
short heavy leads. This ground bus may
then be tied to an external earth grounding
rod.
1.7 HIGH POWER OPERATION: The
TITAN III amplifier operates comfortably
at a maximum of 1500 watts output. New
owners often find that other components in
their station may not. Before operating at
this power level, be certain to check the
following items:
1. The coax from the TITAN III to the
feed point of your antenna must be
top quality RG-8 or better. We
recommend silver plated connectors
rather than chrome plated
connectors. Make sure that all coax
connectors are tight.
2. All coax switches or relays in the
feed line must be rated at 1500 watts
or higher. NEVER ACTIVATE IN-
LINE SWITCHES WHILE
TRANSMITTING.
3. Verify that the components in your
antennas are rated for the TITAN III
maximum power levels (dipole
center insulator, end insulators,
baluns, traps, etc.) Make sure that
all radiating sections are well clear
of metallic objects such as rain
gutters and antenna supporting
CAUTION!!!
Never attempt to operate the TITAN III
without first connecting a suitable
antenna or 50 ohm resistive load of
sufficient power rating or
SERIOUS DAMAGE MAY RESULT!
