Alignment Preparation & Precautions
A 50 Ω RF Dummy Load and in-line wattmeter must be connected to the main antenna
jack in all procedures that call for transmission, except where specified otherwise. 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, in 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 and
30°C (68 - 86 °F). When the transceiver is brought into the shop from hot or cold air, it should
be allowed time to come to room temperature before alignment.
Whenever 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 the alignment procedure are based on
0dBµ EMF = 1µV.
Setup the test equipment as shown for transceiver alignment, apply 13.6V DC power to
the transceiver. Refer to the drawings above for Alignment Points.
