Going Mobile at 150 Watts
Although this book set out to overview the installation of a
mobile 500-watt system using SG-2000 Powertalk transceiv-
er mated with a SG-235 Smartuner and SG-500 Powercube,
we should mention “barefoot” 150-watt systems.
The same advice and procedures covered on cable routing,
mounting methods, and vehicle configurations still apply to
lower power systems. The overall installation will be almost
the same, leaving out the SG-500 of course, and perhaps sub-
stituting an SG-230 for the SG-235.
Auxiliary Battery
The big question will probably be, “Do I need an auxiliary
battery system?” A 100 to 150 Watt HF transceiver typically
draws 16 to 24 amps on transmit (CW). This is about one
fourth the current requirement that its big brother, the 500-
watt Powercube, draws on transmit. Although an unmodified
vehicle charging system can easily handle this load, you may
want to consider adding the auxiliary battery/solenoid sys-
tem anyway. (See Chapter 6.) A few factors favor this sugges-
tion:
• Adds reliability of a backup power source for
cold-weather starting and emergencies. Operators
in regions with sub-zero winter temperatures
may want to consider this.
• Allows for easier future installation of the
Powercube, should you someday decide to
upgrade to 500-watts.
• Reduces overall battery drain and allows
