structures. For the first few hours of
operation, check the SWR
frequently. Any increase in
reflected power is an indication that
something between the amplifier and
the antenna elements, including the
end insulators, is heating and must
be corrected.
4. A solid earth ground is often
essential. Every station will have a
unique electrical ground due to
location of equipment, distance
between units, distance from house
wiring ground rod, distance from RF
ground rod, etc. Keep equipment
ground straps as short and thick as
possible and RF ground rod as close
to the station as possible.
5. If you use an antenna tuner, make all
SWR/matching adjustments with the
TITAN III in the STANDBY mode
using transceiver low power only.
6. If any of your home entertainment
electronic devices have RF leaks, the
TITAN III may find them. If you
are not familiar with standard
procedure for controlling this type of
interference, consult the ARRL
Radio Frequency Interference
Manual.
1.8 ALC: Most solid state transceivers do
not provide connection for ALC input and it
is unnecessary to make any external ALC
connection to these rigs. The ALC output
jack is used primarily with tube-type
transmitters or transceivers with a negative
going ALC system. The ALC ADJUST
control is used to set the threshold for proper
ALC action. This is -1 to -15 VDC
depending on input RF drive level. A
negative output voltage will be present at the
ALC jack only when the TITAN III is in the
OPERATE mode and the input RF drive is
above the threshold setting. Leave this
control fully clockwise if you have no
requirement for external ALC.
1.9 COOLING SYSTEM: The TITAN III
uses a pressurized cabinet with the main air
intake through the right front side of the
chassis and exhaust through the tube
chimneys on the right rear top of the
amplifier. It is safe to operate the amplifier
as long as there are no impediments to the
flow of air near the air intakes and/or the
exhaust.
