Radio Tuning Procedure

General

An IBM PC (personal computer) and RSS (Radio Ser-
vice Software) are required to align the radio. Refer to
the applicable RSS Manual for installation and setup
procedures for the software.
To perform the alignment procedures, the radio must
be connected to the PC, RIB (Radio Interface Box), and
Test Set as shown in Figure 7-1.

plug directly; you do NOT have to use the RSS GET/
SAVE functions to program new tuning values.
Do NOT switch radios in the middle of
any SERVICE procedure. Always use the
EXIT key to return to the MAIN menu
screen before disconnecting the radio.
Improper exits from the SERVICE
screens may leave the radio in an
improperly configured state and result in
seriously degraded radio or system per-
formance.
The SERVICE screens use the concept of the "Softpot",
an analog SOFTware controlled POTentiometer used
for adjusting all transceiver alignment controls.
