PREFACE The members of the Loudoun Amateur Radio Group have considerable experience and expertise in the planning, design, system engineering, development, testing, installation and operation of amateur radio equipment and systems in support of the Group’s own communications needs and most importantly, in providing sustainable and reliable communications services to various public and government agencies in Loudoun County. The Group participates in about six operations annually. Communications support is provided to the Loudoun County Chapter of the American Red Cross, the Amateur Radio Emergency Service of Virginia, the Town of Leesburg, the Goose Creek District of the Boy Scouts of America, the American Radio Relay League Field Day and Loudoun Amateur Radio Group Balloon Launch, Flight and Recovery Operations. Participation range from a dozen plus members for Scouting events to four dozen plus for the annual Field Day Exercise. Many members have successfully completed training conducted by the Amateur Radio Emergency Service of Virginia. Members mobilized and deployed Amateur Radio Emergency Service support to the American Red Cross on September 11, 2001. These services are austere, have single point vulnerabilities and are provided at a considerable expenditure of time, equipment and personnel. It is with this experience that the Group recognizes the need for more efficient and effective radio relay and communications capabilities.

           In developing these user operational requirements, the Group recognizes other in-county and adjacent county communications systems and has no intent to duplicate, but where feasible and of mutual benefit, to encourage integration. Furthermore, the Group recognizes the public services and public safety benefits of this communications system and intends it to be a full period, open service capability for all amateur radio operators and organizations.

           During the development of these requirements the Group consulted with Tom Dawson, WB3AKD,  Emergency Coordinator, Loudoun County, Virginia Amateur Radio Emergency Services, and with   __________   of the Loudoun County Chapter of the American Red Cross.

           These user operational requirements are therefore based upon the above, and the Group trusts these will successfully guide and lead to the time-phased and economically affordable research, development, test, evaluation and operational deployment of the required capabilities.


Objectives

  • Define user operational needs for amateur radio relay and communications services within Loudoun County, Virginia in support of public services, public safety, emergency response, and the operations of the Loudoun Amateur Radio Group.

  • Establish in user terms the required essential radio relay and communications capabilities.

Operational Requirements

A. Emergency and Pubic Safety Communications.

1. American Red Cross. Support disaster operations and training exercises of the Loudoun County Chapter of American Red Cross (LCC-ARC). These LCC-ARC communications requirements are like those provided in 2000 and 2001 for the LCC-ARC Support to the Reston Bike Ride Across Loudoun County and the September 11, 2001 deployment to Dulles International Airport in support of the LCC-ARC. The former is used by the LCC-ARC to train in disaster relief and is also a fund raising opportunity.

a. Provide written message, voice, data including facsimile and automatic position reporting, still photograph and video emergency communications services among the Chapter Headquarters in Leesburg, a minimum of four discrete LCC-ARC support centers within Loudoun County, two mobile command or liaison positions deployed any where in Loudoun County, and an adjacent ARC Chapter or ARC Higher Headquarters. Written message, voice and data traffic entered at any one point will be delivered to any other point within the system within 15 minutes of entry. In addition, support voice communications into the above network by dismounted, low power handheld radios deployed in the vicinity of any disaster site, support facility, or any isolated location in Loudoun County.

b. Initiate deployment of the above capabilities within two hours of activation. Activation will be initiated by request for emergency communications support from LCC-ARC to the LARG Emergency Services Coordinator or designated alternate.

c. Within 8 hours of initial operation at each location, be capability of 24 hour a day operations at that location for a sustain period.

d. Within 2 hours of activation, provide written message traffic entry and exit to at least one external service point as may be requested by LCC-ARC. The specific external service point will be based on circumstances and availability of an external agent. These external communications links may include high frequency radio circuits capable of supporting the required transmission means and where necessary are connected or integrated into overall local Loudoun County networks. 

e. Within 2 hours of activation, provide an on-call or deployable still photographic and video communications link between any LCC-ARC designated remote site and any one fixed user with the network described in paragraph A1a above.

2. Additional Disaster Site Communications Support. While providing the communications to the LCC-ARC in paragraph A1 above, also furnish emergency communications support at a disaster site for other government and/or non-government agencies within Loudoun County. The disaster site may be remote and in an unimproved area of Loudoun County. It is likely that this and some or all of the LCC-ARC requirements will have to be met at the same time. This disaster may be a forest fire, flood, storm damage, missing persons search, plane crash or other event which could tax or limit normal local existing communications.

a. Provide voice, written message traffic and data including facsimile and automatic position reporting communications from the disaster site to a minimum of four responding agency headquarters, staging areas or remote support facilities located within Loudoun County.

b. In addition, support dismounted, low-power, voice handheld radio communications in the vicinity of the disaster site and to a minimum of four remote agencies support sites.

c. As may be required by the Loudoun County Emergency Coordinator, provide one or more external emergency communications links into District 2 Emergency Nets, and a link to the Amateur Radio Emergency Service station in Richmond, Virginia at the Emergency Operations Center of the Virginia Department of Emergency Management. Communications links include high frequency radio circuits capable of supporting the required transmission means and where necessary are connected or integrated into overall local Loudoun County networks.

d. Within 2 hours, provide an on-call or deployable photographic and video communications link from the disaster site to one or more of the supported agencies.

e. Response and full-period operational times are like those required in paragraph A1 above.

3. Emergency Communications Exercises. Periodically, at the call of the Loudoun County Emergency Coordinator of the Amateur Radio Emergency Service of Virginia, emergency communications exercises and drills will be conducted in Loudoun County.
