CHAPTER 1
INSTALLATION
1.1 INTRODUCTION: When setting up
the station, provide adequate ventilation for
the amplifier. Also, select a location that
allows comfortable access to the front
controls and adequate clearance for rear
panel connections.
1.2 ELECTRICAL CONNECTIONS :
The TITAN II amplifier draws up to 18
AMPS at 240 VAC. Care should be taken
not to overload house wiring circuits usually
fused or breakered at 15 to 20 AMPS.
A straight run circuit with # 10 / 2 with
ground and breaker or fuses at 20 AMPS is
strongly advised.
1.3 TRANSCEIVER
INTERCONNECTIONS : When using the
TITAN II with TEN-TEC transceivers with
TXEN-TXOUT connections, follow the
diagram in figure 1-1. The QSK-PTT switch
on the TITAN II should be in the QSK
position for all modes of operation. This
hook-up arrangement will work with the
OMNI series V, VI , and VI+ as well as the
PARAGON I and II.
When connecting the TITAN II with other
rigs, use the diagram in figure 1-2. Note that
the key or keyer must be connected to the
key in jack on the TITAN II, 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 II. When
using this configuration, the QSK/PTT
switch on the amplifier must be in the QSK
position for CW, and in the PTT position for
SSB.
1.4 ANTENNA REQUIREMENTS :
The TITAN II amplifier is designed for use
with antennas resonant at the frequency of
operation and having impedances within the
limits of 25 to 100 OHMS or an SWR of 2:1
or less. Note that other than 1:1 impedances
will result in TUNE and LOAD setting
different from those in the reference chart
(figure 2-7).
The nominal output impedance of the
amplifier is 50 OHMS. Many antennas
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 II to
work into a 50 OHM load for maximum
power transfer to the antenna. TEN-TEC
models 253,229 or 238 are suitable
companion tuners.
CAUTION!!!
Never attempt to operate the TITAN II without first connecting a suitable
antenna or 50 OHM resistive load of sufficient power rating or
SERIOUS DAMAGE MAY RESULT!
