- 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.
