This section includes voltage and troubleshooting charts which should assist the engineer to isolate
and repair the fault. Voltage measurements should be made using a high-impedance voltmeter and
the values given are with respect to ground.
Obvious checks, such as battery performance on load, should be made before pulling the radio apart.
Substitution of another set of batteries, or the use of a power supply, isolates this cause.
The alignment procedures, given in Section 5, list how standard tests such as SINAD measurements
can be made. These can be used to check the performance of the receiver.
Careful alignment, using suitable test equipment, and quality interface cables should ensure that the
radios meet their specified performance.
