Calculating upper base frequencies
Custom Band Plans (800 Custom, VHF, UHF) require that you enter both a lower and an
upper base frequency value. Here's how to determine these values.
The Lower Base Frequency (or Base ) is always the base frequency as provided in the
RRDB. The Upper Base Frequency is calculated from the following formulas:
For sites with a single band plan:
Base + ( (759 – Offset ) ×
Step )
Where:
● Base = the lower base frequency listed in RRDB.
● Offset = the offset for this entry.
● Step = the step for this entry.
For sites with multiple band plans:
Upper Base
n
= Base
n
+ ( Offset
n+1
– 1 – Offset
n
) ×
Step
n
Where:
● Base
n
is the lower base frequency for the entry.
● Offset
n+1
is the Offset for the next band plan (for the last table, use 760)
● Offset
n
is the offset for this band plan
● Step
n
is the step for this band.
