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
Step

Where:
