Tools, Equipment and Spares
Torque-drivers
For level-1 and level-2 repairs, excluding SMT repairs of the circuit boards,
the following torque-drivers are required.
■
For level-1 repairs Torx T6, Torx T10, and Torx T20 driver bits are
necessary.
■
For level-1 repairs, 3/16 inch and 14mm long-reach sockets are
required.
Refer to the illustrations in
“Reassembling the Radio Body” on page 137
for the corresponding torque values.
Tools for SMT
Repairs
In general only the standard tools for SMT work are required for level-2
repairs of the circuit boards. In addition, a can-removal tool is recommended
but if none is available, a hot-air tool may be used instead. However, it
should be noted that a hot-air tool affords little control. Even in skilled
hands, use of a hot-air tool to remove cans will result in rapid uncontrolled
rises in the temperature of components under the can being removed as well
as under any adjacent cans. The circuit board might suffer damage as a result.
Test Equipment
The following test equipment is required for servicing the radio:
■
test PC (with programming and calibration applications loaded)
■
RF communications test set (audio bandwidth of at least 10kHz)
■
oscilloscope
■
digital current meter (capable of measuring up to 20A)
■
multimeter.
■
DC power supply (capable of 13.8V and 20A for the 40W/50W radios,
and 10A for the 25W radios)
■
spare control head
■
service kit.
Separate instruments may be used in place of the RF communications test
set. These are an RF signal generator, audio signal generator, audio analyser,
RF power meter, and modulation meter.
