SUBJECT: OPS - Why simplex frequencies? Part 1/2
[This subject really incorporates two categories: planning under
MANAGEMENT and utilization under OPERATIONS. For simplicity we
are listing it under the OPERATIONS category.]
Why use simplex 2-Meter frequencies when a repeater will do
just as well? Some reasons are unique to individual
organizations; others are common to all. One reason is to get
off a wide area channel when a simplex frequency will do. In
public safety systems the repeater channel may be used for
routine dispatch and communications, while a simplex channel is
used only for the tactical and exclusive needs of the incident.
On Public Safety, Civil Air Patrol, and MARS channels the users
are disciplined and controlled. This is not always so on Amateur Radio
frequencies. A compromise in the ham bands is to move to a simplex
frequency. More important, a move to a frequency that is NOT part of
any national simplex plan. Why? All to often that's where the non-
participants and unwanted operators will look for you. Another reason
is that there are some hams, believe it or not, who feel they own a
simplex frequency in their area.
