The Karo-Echo Coordination Team: Don, NI6A, team lead
Job Duties: To coordinate radio frequency usage for radio disaster services in order to minimize interference on Ham, GMRS, FRS, and Digital Networks and establish a Message Center protocol to coordinate and maximize inter-operability between networks, as well as to titrate message precedence.
Communications Coordination encompasses two critical domains
1: Ham Radio Simplex Frequency Coordination
A: Ham Radio Simplex Frequency Coordination between all Karo/Echo CERT Areas and the EOC
B: Ham Radio Simplex Frequency Coordination with neighboring EMcomm (Emergency Communications organizations and ACS (Auxiliary Communications Systems) Outside of Kensington/El Cerrito
2: FRS/GMRS Frequency Coordination
Each CERT Area will cooperate by reporting their primary and secondary FRS and GMRS frequencies. Frequencies/channels should be staggered in order to avoid inter-area interference between adjacent CERT areas. Intra-area channel choices are relegated to the individual CERT area coordinators, but should be coordinated through KE's Coordinating body. Each Area shall do their own intra-area mapping in the attempt to establish 100% communication between FRS block stations and Ham radio dual station or GMRS/Ham dual stations for relay to the Area ICP without the need for relays, if possible.
The following CERT areas have applied for the following frequencies.
CERT Area EC9: FRS/GMRS Channel 7 primary and FRS/GMRS Channel 2 secondary Status: Coordinated
CERT AREA K6: FRS/GMRS Channel 6 primary and FRS/GMRS Channel 1 secondary Status: Coordinated
CERT AREA EC4 FRS/GMRS Channel 2 primary and FRS/GMRS Channel 7 secondary Status: Coordinated
- Channels 8-14 are restricted to 1/2 watt for both GMRS and FRS and are to be used intra-block (SAR, Triage, Fire Suppression, etc)
- Channels 1-7 are for longer comms such as inter-block comms to and from the AREA ICP where GMRS are allowed 5 watts and FRS 2 watts maximum.
GMRS/FRS Mapping: Each CERT Neighborhood Area should be mapped so that block dead spots and hot spots are identified and remedial measures implemented.
Frequency Coordination between CERT areas (Inter-Area) through the use of Amateur Radio and GMRS Interfaces
The KARO/ECHO primary frequency 146.415 MHz with 146.475 MHz as secondary.
The assigned Contra Costa County OES frequency for KARO/ECHO CERT is 146.475 MHz simplex.
No GMRS inter-area coordination has yet been established.
2 Meter Mapping: Each Ham location should map all ham stations that they can establish direct contact. This can be done as a weekly net exercise. Each ham station should have the capability of contacting the EOC on simplex. (This must be tested on regular basis).
Coordination with neighboring EMcomm organizations
Communication and coordination is necessary in order to minimize interference and to arrange for mutual aid if needed, since, many disasters are local and not widespread equally among geographical regions. Mutual-aid can take the form of training exercises, skilled operators, and sharing needed resources such as water, food, medicines, generators, skilled nursing, rescue equipment etc. This is especially valuable if our local agencies are overworked and unavailable.

3. Coordination with local NGOs to Aid Messenger Services Local running, bicycling, Scout Troops, PTAs, service organizations, and Church orgnizations are potent resources to run messages within the CERT areas need to be recruited and trained to act as transcribers/scribes, crowd control, runners, and message center managers.
4. Training in Efficient message center operations should be made available as well as FRS/GMRS and radio training classes. Since smooth Interoperability is key, all radio frequencies should be coordinated by the KAROECHO Coordination body.
Not only ham frequencies need to be coordinated in order to avoid interfence; but also FRS/GMRS CERT frequencies. A message center model for each ICP must be established so that messages can be triaged/titrated and handed off from one service to the other be it by ham, FRS, GMRS, runner, or bicyclist.
Cert blocks and CERT Area ICPs must be COORDINATED as to frequencies or they will interfere with each other. Interference with neighboring CERT areas such as Berkeley, Albany, and Richmond on our borders can and should be avoided, through coordination.
