The Community Emergency Response Teams (CERT) purpose and function in a disaster

"The Community Emergency Response Team (CERT) Program educates people about disaster preparedness for hazards that may impact their area and trains them in basic disaster response skills, such as fire safety, light search and rescue, team organization, and disaster medical operations. Using the training learned in the classroom and during exercises, CERT members can assist others in their neighborhood or workplace following an event when professional responders are not immediately available to help. CERT members also are encouraged to support emergency response agencies by taking a more active role in emergency preparedness projects in their community. The CERT concept was developed and implemented by the Los Angeles City Fire Department (LAFD) in 1985." accessed 04-17-2019

Why and how GMRS and FRS Radio Services Interface with the Amateur Radio Service (ARS)

It is difficult for new disaster volunteers to imagine a widespread power outage, telephone outage, cell phone and SMS texting outage, and an internet outage occurring simultaneously; yet experienced amateur radio operators know this occurs all too well, and are prepared to act.

Because there are a limited number of FCC licensed amateur radio operators to cover emergency communications for every block in Kensington and El Cerrito, local CERT block captains will benefit by utilizing FRS/GMRS radio communications in disasters should conventional means of communications and power such as, internet, telephone, cell, and SMS texting fail or be overloaded.

Although it is not the purview of KAROECHO to provide FRS/GMRS (Family Radio Service/General Mobile Radio Service) communications within blocks and/or from block to area Incident Command Posts (ICPs), KAROECHO offers expert FRS/GMRS radio instruction and interface for CERT Area Coordinators (AC), if so desired. Each CERT AC must plan how they will communicate within their own area, to and from the Emergency Operating Center (EOC), and to neighboring CERT areas for mutual aid. Interface between the three services (FRS, GMRS, and ARS) are most efficiently facilitated through message center manager training. KAROECHO will also offer instructions on how to radio map your area and coordinate channel usage so that interference between neighboring CERT FRS/GMRS radio operations will be minimized. CERT volunteers are welcome to contact for further information on how to get the job done.

KAROECHO, being a dedicated amateur radio organization focuses on providing wide area (tier three) auxiliary communications between Area ICPs/staging areas and the Emergency Operating Center (EOC), as well as inter-area communications for mutual aid.

Critique: Pros, Cons, and Limitations of FRS/GMRS Radios Use

Since FRS radios power output has a limited range from 1/2 to 2 watts maximum, they are inherently limited in distance. They are also limited by their small lossy integral antenna and crowded channels. Hence, their communications among themselves (FRS to FRS) is severely limited. However a GMRS station with an outdoor antenna may be required to hear them further than a few blocks, as GMRS stations can employ external gain antennas. If no GMRS station is available, then relays will have to be implemented, thus increasing the possibilities of error and decreasing timeliness.

The second FRS limitation are the limited available frequencies. Only channels 1-7 allow FRS 2 watts. Thus interference with neighboring blocks as well distant blocks who are in the hills may be a hindrance. Further difficulties due to location may occur because the Kensington/El Cerrito hills are in direct line of sight to parts of Oakland, Berkeley, Marin, San Francisco, Richmond, and San Pablo; which are potential sources of interference due the lack of available channels and coordination.

Remedy: Send INTRA-Block comms off to the low power channels 8-14 using 1/2 watt, thus lowering the possibility of interference. Then after the intra-block traffic is cleared, these stations should return to the Block’s assigned main (2 watt) channel unless directed to otherwise by the block captain.

Tier 2 interference with other areas will most likely be a problem because of the limitation of only seven 2 watt FRS channels. Coordination is thus helpful to avoid interference.

It is noted that channels 15-22 allow FRS 2 watt operation; but they will be competing with 50 watt repeater outputs and/or 50 watt GMRS simplex operation, both. Therefore the effective usage of FRS channels 15-22 may be predictably poor. FRS operator are suggested to use channels 1-7 for long distance and channels 8-14 (1/2 watt maximum) for light SAR and very short distances.

Never-the-less FRS/GMRS communications are the only feasible intra and inter-block radio alternatives available at present, other than by runners or bicyclists.

There are currently not enough amateur radio operators (hams) to provide block to block and block to CERT Area Incident Command Posts, and also communicate from each area command center to the Emergency Operations Center (EOC). The plan is to hand off FRS/GMRS messages to the hams at our CERT area Command posts (CPs) message center, who then can relay to the EOC and/or to neighboring areas. More ham radio operators are needed. Ham radio requires a license that is granted after passing a test. Free study courses are available in our area. See the KaroEcho GET INVOLVED page for updates.

Why We Set Privacy Codes (Interference Filters) OFF

Privacy codes are not private; it's a misnomer. So-called privacy codes limit what your receiver hears from radios who transmit the privacy code (usually a sub-audible tone). Radios that have their privacy codes set to off will hear all transmissions on the channel regardless of privacy code settings on other radios. Setting privacy codes to "off" will allow you to hear transmissions from radios who do not have sub-audible transmitting tone capabilities, radios that have incorrect privacy tones set, and stations that have their transmit privacy tones off. But the most important reason to set privacy tones off, is to not interfere with other stations who may be transmitting; but you do not hear them if your receive privacy tones are set "on". Granted there will be more unwanted conversations on your channel when privacy tones are set "off"; but you will be guaranteed to hear the station that is trying to call you.

Also set emergency alerts, roger tones, transmit beeps, and other bells and whistles OFF, as well.

How to obtain your GMRS License

FRS does not require a license; however, severe, power, antenna, and channel restrictions apply alongside of disallowing repeater use. A GMRS license will greatly improve your communication capabilities for a one time fee of $70.

The FCC web pages allow for on-line GMRS licensing. The application fee is presently $70 for 10 years with no charge for renewing.

You will need an FCC Registration Number (FRN) and password. If you don't have an FRN and password, you can obtain them by registering online with the FCC Commission Registration System . To use GRMS frequencies, the FCC requires you to obtain a license. To get a license you don’t have to take an exam, but you will need to fill out the required forms and send your payment.

Obtaining an FRN

First you must obtain an FRN number (FCC Registration Number).

There is no charge to obtain an FRN. However, there is a fee when you apply for your license. To obtain your FRN go to FCC Registration Page

Select "Register" complete the online questionnaire (it is very simple and takes less than 1 minute) . You will receive your FRN immediately upon completing the one page online form. Then you can move to the next steps below.

GMRS Application Process

The process to obtain a GMRS license is fairly easy. You can apply for a license on-line by following the steps below.
