Step 4.  Leave the tuning probe in cavity “H1” and adjust 

tuning screw 2 for a DIP.

Step 5.  Insert the tuning probe into cavity “H2” and adjust 

tuning screw 3 for a DIP.

Step 6.  Insert the tuning probe into cavity “H3” and adjust

UHF Tuning Procedure

Use one of the following two methods to calculate the alignment 
frequency to be generated by the signal generator.

For stations with a single receive frequency, calculate the frequency 
of the alignment signal as follows:

Step 1.  From the site documentation, or the RSS, determine 

the station receive frequency. Add 200 kHz.

Step 2.  If the Receiver Module is Range 1, determine the 

alignment frequency as follows:
