41. 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:
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:
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.
For example:
Custom Frequency Table
Entry Base Spacing
Offset
A 155.4150 15.0 380
B 157.2000 12.5 436
C 157.4700 15.0 454
Base
+ ( (759 –
Offset
) ×
Step
)
Upper Base
n
=
Base
n
+ (
Offset
n+1
– 1 –
Offset
n
) ×
Step
n
