Join Carroll ARES

Details
Published: 23 January 2015

Carroll County Amateur Radio Emergency Service (ARES) is always looking for new members.

Emergency Communications is a part of the service amateur radio operators return for the allocation of radio frequencies to our hobby, and ARES is one of the several ways to serve. ARES is intended to be a resource for:

 

  • Hospitals
  • Local, Regional, and State Agencies
  • National Weather Service (SKYWARN)
  • Other NGOs (Non-Governmental Organizations)
  • Community Events
Membership is free, requiring only that you fill out a membership application and mail it to Brian Keahl, 925 Old Draketown Trail, Temple, GA 30179.
While ARES is happy to have untrained Amateur Radio Operators as members, we also encourage them to take some basic FEMA courses, ARRL courses, and participate in our weekly training nets and activities.  However, the additional training activities are voluntary and optional - although served entities often require members to have some of the training for deployment.

I hope you'll take the time to join us on our weekly net, on the N4FWD repeater (146.640-131.8) on Thursdays at 8:00PM.

 

Emergency Communication Techniques

Details
Published: 12 December 2014

EMCOMM techniques are different from everday communications because of the stress, competing demands, and uncertainty that surrounds the sudden onset of an emergency. Life and death communications are not part of our daily experience. In an emergency, any message may literally affect the lives of patients, stranded civilians, or shelter inhabitants. An unclear message, or one that is altered, delayed, misdelivered, or lost can have disastrous results.

Listen
Listening is half of an emergency communicator's job. You can't communicate the a message if you don't actually hear it. You must learn to focus on receiving the message and tune out distractions.

Sometimes the job of listening is made more challenging because you are operating in a noisy environment or there may be static or interference on the frequency.

Speak Clearly
How you use your microphone seems simple, but there are many things that could affect how well your audio sounds. Each microphone has different pickup characteristics and the radio may applify the signal differently. In theory, the optimum method of transmitting is to hold the mic close to your cheek, and just off to the side of your mouth. Talk across, rather than into, the microphone. This will reduce breath noises and "popping" sounds that can mask your speech.

Always speak in a normal, clear, calm voice. Speaking loudly can result in over-modulation and distortion, and will not increase volume at the receiving end. Remember to speak slowly when communicating a message and at a regular pace when communicating tactical traffic.

"Voice operated transmission" (VOX) is not recommended for emergency communication since background noise or an impromptu discussion can trigger it.

When using a repeater, be sure to leave a little extra time between pressing the push-to-talk switch and speaking. Signal detect time, CTCSS (often called pl) decode time, transmitter rise time create a delay between the time you key the microphone and the repeater is retransmitting your words. A short pause after keying the microphone will ensure that your entire message is transmitted, avoiding time-wasting repeats for lost first words.

Lastly, pause a little longer than usual between transmissions any time there is a possibility that other stations may have emergency traffic to pass. A count of "one, one thousand" is usually sufficient.

Net Control Operator Best Practices

Details
Published: 24 July 2014

Types of nets:

Open Net

Stations call each other and directly pass traffic. A typical example would be a Tactical Net or our Stand-By Weather Nets.

Directed Net

Stations only call Net Control directly. Passing of traffic is controlled by Net Control station.


How a directed net works

A directed net has an active Net Control station who coordinates traffic. The ARES/EMCOMM net is an example of a directed net. Stations wishing to deliver a message or pass information would first call Net Control, and when acknowledged, make your request. Net Control will then coordinatethe passing of traffic or

International Distress Frequencies

Details
Published: 21 November 2014

Most distress frequencies fall within the HF spectrum.  Many HF radios will operate, at least in receive mode, outside of the amateur band, allowing us to monitor those frequencies.  In addition, there are actually recognized Amateur Radio Distress Frequencies.

For most of the history of radio communications 500 kHz has been the recognized international distress frequency for sea.  While it is supposedly still monitored, it has ceased to be used as a primary sea distress calling frequency as of 2010. Other frequencies are being officially phased out, but that doesn't mean someone might not attempt to use it, especially if that's all they have.

Aircraft utilized 121.5 mHz and 243 mHz, usually monitored by commercial aircraft and airports. These were also monitored by satellite but was discontinued in 2010, partially due to the high number of false alarms. These systems are still used in General Aviation aircraft. Maritime vessels also use 156.8 for short-range distress communications, similarly phased out in 2010.

Activation

Details
Published: 04 December 2011

We’ve discussed activation with regards to weather nets and the rules there apply here as well, but I would like for us to expand on them.

We normally initiate informal Weather Nets when severe conditions exist or warnings have been issued. Typically it is “Self-Activation”, because we know to switch to the repeater frequency to begin reporting any sighted conditions. However, everyone has a different idea of what is “severe”, so there is often no clarity of when to open an informal net or elevate to a higher level net. However, the process for the most part works for us and should continue.

Served agencies are another matter. We may not even be aware of a situation where our services may be needed or when. As a result, a more formal system is required. The formal system is also a portion of our Weather Net protocol.

The Activation system is initiated by the served agency. The served agency will have a primary and several backup contacts for initiating deployment. Once the served agency makes contact with any one of the activation liaisons the remainder of the process falls on our organization.
