Alignment Preparation & Precautions

A dummy load and inline wattmeter must be connected to the main antenna jack in all

procedures that call for transmission. Correct alignment is not possible with an antenna.

After completing one step, read the following step to determine whether the same test

equipment will be required. If not, remove the test equipment (except dummy load and
wattmeter, if connected) before proceeding.

Correct alignment requires that the ambient temperature be the same as that of the

transceiver and test equipment, and that this temperature be held constant between 20°C
and 30°C (68°F and 86°F). When the transceiver is brought into the shop from hot or cold
air it should be allowed some time for thermal equalization with the environment before
alignment. If possible, alignments should be made with oscillator shields and circuit boards
firmly affixed in place. Also, the test equipment must be thoroughly warmed up before
beginning.

Note: Signal levels in dB referred to in this procedure are based on 0 dBµ = 0.5 µV (closed
circuit).
