Radio Alignment Procedures: Utilities

 

 

5.Adjust the input level to reflect the next soft spot value. Repeat steps 3 and 4 to tune the next value.

5.5.4RSSI Display Tuning

1.Under the Rx Align menu, select RSSI Display Tuning.

2.Inject an on channel signal to the radio at -47 dBm at the frequency listed. Modulated the signal with a 1 kHz tone at 60% deviation (3 kHz) to verify the radio is receiving the desired frequency. RSSI tuning is only done at 25 kHz channel spacing.

3.Change the level to that which is needed to produce 12 SINAD (approximately -119 dBm).

4.Press the Update button for the soft spot to be tuned to the RSSI value correlating to the applied level. The programmed RSSI value will be displayed.

5.Adjust the input level to -90 dBm.

6.Press the Update button for the soft spot to be tuned to the RSSI value correlating to the applied level. The programmed RSSI value will be displayed.

5.6Utilities

5.6.1Program Serial No.

The Program Serial No. option under the Utilities heading allow the radio serial number to be programmed. However, the serial number of a particular radio can only be programmed if it was originally blank. If the serial number of the radio was not blank, then access to the screen will be denied.

5.7Radio-to-Radio Cloning

1.Cloning is the process of copying the content of one radio (source radio) into another radio (desti- nation radio). Radio content refers to system-type features such as frequency, squelch type options, trunking, etc.

Note: The source radio’s serial number cannot be blank.

Radio functionality inherent in one radio cannot be cloned to another radio that does not contain the same functionality. Tuning and alignment information are not transferable and are not affected by cloning.

1.Signaling Identification Numbers (IDs) are duplicated in the cloning process. Unique IDs may be assigned with the CPS.

Note: Unsuccessful cloning attempts generates a continuous tone and may be an indication that the destination radio’s codeplug is corrupted.
