UNPACKING
Carefully remove the transceiver from the shipping carton
and examine it for evidence of damage. If any damage
is noted, immediately contact the transportation com-
pany responsible for delivery or return the unit to the dealer
from whom it was purchased. Keep the shipping carton
and all packing material for the transportation company
to inspect. The original carton and packing material
should be retained for repackaging should it be necessary
to return the unit. Inspect the packing material for any
accessories or printed material before storing the box.
Locate the registration card, fill out, and immediately
return to the R. L. Drake Company to insure registration and
validation of warranty.
LOCATION
The location of the transceiver is not critical so long as
adequate clearance is provided to allow air circulation
in and around the unit, especially adjacent to the rear
panel mounted heatsink. To prevent overheating, do
not cover any ventilation slots in the top cover.
FIXED INSTALLATION
After unpacking the unit and checking that the in-
tended AC line voltage matches the internally set range
(factory set for 115 VAC) and corresponding fuse is
installed, connect the antenna system to the appropri-
ate antenna input(s). Connect AC cord to mains
voltage. Connect any other external equipment at this
time. Refer to Figure 3 for the diagram of a typical fixed
installation.
4 Installation
PORTABLE/DC POWER INSTALLATION
For use in a portable environment, the transceiver
includes an unfused external DC input connector. This
connector is located on the rear panel. The transceiver
will operate with a DC input voltage of 11-16 VDC. Full
high power RF output during transmit is insured with a
nominal supply voltage of 13.6 VDC or higher, as are
supplied by typical automotive systems. The transceiver
may be powered from the vehicle’s cigarette lighter
socket. An approved method is to make fused wire
connections at the vehicle battery. Connect DC power
observing correct polarity and fusing (10 A Fast Blow
maximum) to avoid possible vehicle wiring damage
and/or fire. Connect the antenna(s) to the appropriate
antenna input(s) using 50 Ohm coax between the
antenna and the transceiver.
ANTENNA REQUIREMENTS
The receiver incorporates internal switching to allow two
separate antenna systems to be connected simulta-
neously. The unit will transmit out the ANTENNA 1
connector only, so a resonant 2-meter antenna must be
connected to ANTENNA 1. A separate single-band or
multiple-band antenna can also be connected to the
ANTENNA 2 connector. By simple setup programming,
either of the connected antennas can be split to either
receiver ‘A’ or ‘B’ for the receive mode. Additional
setup programming permits dedicated antenna usage
or automatic antenna selection by corresponding band,
VHF/UHF, or by frequency range. The typical antennas
for use with this transceiver will include Verticals, Beam,
or Ground Plane types with 50 Ohm coaxial cable feeds.
The best antenna will depend upon the desired fre-
quency coverage and the intended communication link
distance.
