San Luis Obispo County CA
The following document provides an overview of the upcoming conversion of
County Net as the primary dispatch channel for CDF-San Luis Obispo. The date
of this conversion will be March 1st 2004.
OVERVIEW - DISPATCH NET
This is the radio net that you are dispatched on. This may be your local
fire department’s dispatch net. Examples are: County Fire Net, PRF, ATA,
BOB, MRB, SBY, CMC, SLO, AYG, GRO/OCE, and HCF dispatch frequencies.
SLU ECC Agencies
If you are a SLU ECC contract agency or a CDF/San Luis Obispo unit, your
dispatch channel is County Net (154.385).
Responding to the Incident
When dispatched to a call in your jurisdiction, you confirm your response,
travel to the incident, and give a report on conditions on County net.
Switch to Command and Tactical nets after the report on conditions is given
on County Net. All responding units are to remain on County net until they
have arrived at scene. When arriving at scene, it is not necessary to advise
ECC that you are is changing to the Command Net.
When you are dispatched to another jurisdiction incident, your response and
travel to that incident will be on County Net. As you approach the radio
zone of the agency having jurisdiction for the call, you report “switching
to Command Net” to SLU ECC on County Net, then switch to the Command or
Tactical frequency as directed by the I.C. at the scene. It is not necessary
for the unit to be at scene to switch to the Command Net. The unit should
change to the Command Net when they are in the Command Net influence area.
All communications between responding units and SLU ECC will be on County
Net unless directed otherwise. County Net will serve as a “Guard” or
“Hailing” Net in the event SLU ECC or others need to contact resources that
are responding. Once SLU ECC is notified of the change to Command Net and
report on conditions is completed, no other radio traffic from that unit is
needed or expected until the assignment is completed.
Upon completion of the assignment units will advise SLU ECC their available
status on County Net, and will travel back to their area on County Net to be
available for any new emergency assignments. All routine traffic should be
conducted on Local net. If a resource is available at scene, no notification
to SLU ECC is necessary by the individual units. It is advisable for the IC
to let SLU ECC know there are resources available at scene in case
additional emergencies occur.
COMMAND NET
The purpose of the Command Net is for communication between the Agency
having jurisdiction (AHJ) dispatch center and to various Command functions
on the incident. When you arrive at the emergency you Do NOT need to advise
SLU ECC you are switching frequencies, it is assumed that the switch will be
made upon arrival at the incident. Limited command nets are currently
available and others are being developed on a regional basis.
TACTICAL NETS
Tactical frequencies are assigned to an incident for on-scene radio
communications. Their purpose is to provide each incident a different
frequency(s) to minimize interference in multiple incident situations, and
to keep the Dispatch Net available for its designated purpose. Tac Nets are
used for communication on an incident between the Incident Commander and the
resources assigned to that incident. SLU ECC will manage and assign Tactical
Nets that do not belong to the AHJ.
If the incident lies in an area dispatched by SLU ECC, a Tactical Net will
be assigned when the resources are dispatched. If the Incident Commander
needs multiple Tac Nets, the additional nets should be requested from SLU
ECC.
For incidents in areas not dispatched by SLU ECC, the AHJ can use their
agency tactical net or have their dispatch center request one from SLU ECC.
The AHJ will request a Mutual Aid Tactical net from SLU ECC when it is
anticipated the incident will require Mutual Aid. The request for tactical
nets from SLU ECC should be done as early in the incident as possible,
preferably during the initial assignment.
SAN LUIS OBISPO COUNTY FREQUENCIES
DISPATCH NETS
County Net (R 154.385, T 156.030 Tone 82.5)
This is the primary dispatch frequency for CDF/San Luis Obispo and those
agencies that receive contract dispatch services from SLU ECC. This
frequency is also used as a mutual aid coordination channel between dispatch
centers and mobile resources responding to mutual aid requests between
jurisdictions. It also functions as a hailing net. Any time a resource has
an EMERGENCY, they can contact SLU ECC on County Net. SLU ECC can also
contact any resource on this frequency to advise them of a change in
assignment. The use of this net as a Talk Around frequency is forbidden.

COMMAND NETS
CDF Local Net (R 151.325, T 159.315)
This is a Command Net and operations/logistics net for CDF/San Luis Obispo .
This net uses a mountain top repeater system to broadcast a signal to
certain parts of the County. Only one mountaintop repeater is activated at a
time and the radio signal is broadcast only in the area covered by that
repeater. The transmitting radio operator must select a “tone” to activate
the repeater they desire to use.
CDF-Command 1 (R 151.355, T 159.300)
CDF-Command 1, a statewide repeated frequency that is used as a command
frequency for communications between CDF ECC’s, Incident Commanders,
aircraft, and command staff. It may be used for flight following and for en
-route communications between responding and returning mobile units. Use
car-to-car whenever possible.
CDF-Command 2 (R 151.265, T 159.330)
CDF-Command 2, a statewide repeated frequency that is used as a command
frequency for communications between CDF ECC’s, Incident Commanders,
aircraft, and command staff. It may be used for flight following and for en
-route communications between responding and returning mobile units. Use
car-to-car whenever possible.
CDF-Command 4
CDF Command 4 is used for the same purposes as CDF 1 and CDF 2. CDF Command
4 is not yet available, but should be installed on local mountain tops in
the next several years.
RIVER COMMAND (R 154.235, T 150.805) A repeated Command frequency available
for incidents in the Salinas River area and other portions of the North
County that the repeater is accessible to. (Paso Robles Command 3)
BAY COMMAND (R 154.130, T 156.00) A repeated Command frequency available for
incidents in the Morro Bay area and other portions of the North Coast that
the repeater is accessible to. This frequency is labeled as Estero Command
on some plans. (Morro Bay Fire Net)
5 CITIES COMMAND (R 154.145, T 158.775) A repeated Command frequency
available for incidents in the Five Cities area and other portions of the
South County that the repeater is accessible to. (Pismo Beach Fire Net)
WHITE FIRE 1 (154.280) An OES Fire and Rescue Branch intersystem frequency
that serves as a mutual aid command net that is specifically limited to
mobile to dispatch center and dispatch center to dispatch center
communications. This frequency should not be used as a tactical frequency
unless all other options are exhausted.
TACTICAL NETS
WHITE FIRE 2 (154.265) An OES Fire and Rescue Branch intersystem frequency
that is a mutual aid TACTICAL frequency to be used by tactical resources at
scene.
WHITE FIRE 3 (154.295) An OES Fire and Rescue Branch intersystem frequency
that is a mutual aid TACTICAL frequency to be used by tactical resources at
scene.
CDF TACTICAL FREQUENCIES CDF Tac’s

8 (151.370) Assigned to North County
CALCORD (156.075) As an adjunct to the other mutual aid channels dedicated
to law enforcement, in the 1980’s California realized that some situations
such as hazardous materials spills require the use of resources other than
law enforcement. A need was identified for a channel to coordinate the work
of multiple disciplines that might be needed to mitigate the incident.
CALCORD was developed to allow two-way radio communication between law
enforcement, fire service, emergency medical, and public works – whatever
services were involved in the specific scene of operations. In San Luis
Obispo County, CALCORD will be used in mobile and portable units at the
scene of any emergency incident requiring coordinate action by more than one
agency type. CDF/San Luis Obispo has chosen to adopt this frequency as the
tactical net on all of their EMS calls as they are often multi agency
involving fire department, law enforcement, ground and air ambulances. Use
of the system will be limited to emergency operations only, with the
exception of tests and drills.

TRAVEL/HAILING NETS
CALIFORNIA TRAVEL NET (R169.125, T168.325) The California Travel Net is a
USFS radio frequency shared with CDF under a formal agreement. It is also
known as CTNT, CA Calling Net and Region 5 Travel Net. The Travel Net is
designated for use by resources en-route to or from any incident outside of
their home unit or forest. California Travel Net is also available for use
as a flight following and local aircraft dispatching frequency. THIS
FREQUENCY IS RESTRICTED FROM ALL TACTICAL USE AND ADMINISTRATIVE
COMMUNICATIONS.
Authorized uses are:
• Emergency vehicle-to-dispatch communications
• Emergency car-to-car communications
• Initial call, recall and redirection of personnel and equipment
• As a contact channel during long distance assignments.
• Flight following and local aircraft dispatching
Strike teams or personnel dispatched out of their local area are to monitor
the Travel Net while in route to an assigned incident or
mobilization/staging area.
SLO COUNTY FIRE DISPATCH NET
Because of its County wide accessibility, County Fire net can be used as an
EMERGENCY hailing net. It is not to be used as a chat channel, but can be
used when resources are unable to talk to other dispatch centers during
emergencies.
OUT OF UNIT RESOURCES
RADIO PROCEDURES
'Repeaterized County Fire Net' is not programmed into CDF statewide Kenwood
or Bendix King radio groups. This will pose a problem for out of Unit
resources covering San Luis Obispo Unit. ECC dispatch procedures, when Out
of Unit Resources are assigned to San Luis Obispo Unit, will be to dispatch
on both County and Local nets by simulcasting. Local net will continue to be
available as a dispatch net for out of unit resources without County net
capability [are] covering our stations.
ECC is currently working on a solution to alleviate having to simulcast.
Some proposed solutions are…
1. Assigning a county dedicated pager to each station, to be used by the
covering unit.
2. Setting up a handy talkie group dedicated to San Luis Obispo County
frequencies to be cloned to that unit’s handy talkie.
3. Assigning cloning cables to each Battalion Head Quarters.
These solutions will take time and money. No date has been set to implement
these procedures.
FREQUENTLY ASKED QUESTIONS
1. Why are we making the change to County Net for dispatching?
As San Luis Obispo County Fire Agencies become busier, having separate nets
for dispatching and incident traffic will create smoother communication flow
for on going incidents and for new emergencies. There will be less
competition for airtime. County Fire Net has been chosen as the Dispatch Net
because it covers all areas of the County at the same time. San Luis Local
Net requires a special tone be selected to activate each Mountaintop. This
means stations in the North County may not hear what is going on in the
South County, and vice versa.
2. Who will this affect?
This change will affect all SLU ECC emergency resources, CDF fire stations
and camps, and contracting agencies (CAY, CMB, TEM, SMV, SMF, PSM, Avila),
and mutual aid participants.
3. Where is this new county net in our radios?
In both the state and county radio plans, group 2 has only one frequency in
it and that frequency is the new county net repeater dispatch frequency. You
will have to go in to your aux-C group and delete county net and add San
Luis County Repeater frequency into your aux-C group.
4. When do I switch from the dispatch net to the command net?
When responding under the control of SLU ECC, you will switch to your
assigned command net, after you go at scene and have given a report on
conditions. When responding into another AHJ, you will switch frequencies
when you reach their jurisdiction. For example: E30 responding into PRF
would confirm response on dispatch net and notify ECC they are switching to
River Command, E21 responding to a call in AYG jurisdiction and would
confirm response and travel on the dispatch frequency and as soon as they
are able to contact Five Cities Command or arrive at scene, they would tell
San Luis “Switching to Five Cities Command”.
5. Why don’t we just immediately switch to the command net after the initial
dispatch?
Not all responding resources can hear your radio traffic if you immediately
switch to a command net. Additionally, your report on conditions should be
given on the dispatch frequency so that incoming units receive current
incident status. In the future, as our call load increases and our command
net coverage improves, we will move to a true dispatching net.
6. On which frequency do I give my report on condition?
Your report on conditions will always be given on the dispatch frequency.
Updated report on conditions will be given on the command net.
7. What happens to Local net?
All SLU routine radio traffic will continue to be conducted on Local Net,
including chief officer status, equipment out of service, and equipment
delays. It will still be a reapeaterized net, but will not be used as a
dispatch frequency. It will become a command net and/ or logistical net, a
net that we can talk back and forth to each other without interfering with
the ECC’s ability to dispatch new emergencies. In the rare occasion when we
have out of county resources in the unit who do not have our dispatch net in
their radios, the ECC can still dispatch them on local net because our
stations quick calls are able to be activated on both county and local nets.
Local net will continue to be available as a dispatch net in case county net
fails or out of unit resources without County net capability are covering
our stations.
8. Will ECC continue to simulcast on both County and Local net?
No, not after the March 1. 2004 transition. Simulcasting was a temporary
stop gap measure to bring us to this point. The only exception will be when
'out of unit resources' are committed to SLU stations local net will be used
to dispatch these units.
9. On what net will notification radio pages be sent out?
County net will be used for incident driven radio traffic only. The
exception to this rule will be radio notification pages (EG: company drill
notifications, out of service notifications).
10. What is Estero Command?
Estero command is a frequency name in some of the Kenwoods. This was the
original name for Bay Command, but what deemed to be too wordy. Estero
Command is the old name for the current Bay Command.
11. If I have emergency traffic, which net do I use?
All emergency traffic should take place on County Net. If you are unable to
use County Net, Local Net will still be available.
