Station 75 up and running

Saturday a few of our members met and finished setting up Fire Station 75's radios.  This puts us at a halfway mark on this project.  Stations 73, 74, and 75 are ready to go. 71 and 72 are still under construction and 76 is in the planning stages.  Special thanks to all those that have worked on these projects.  In the upcoming months we are planning an activity where we activate all available stations to very everything is working a designed.

Saturday - Firestation 75

For those that are interested I am going to be at Station 75 Saturday at 9:00 AM to finish up the wiring job we started last year.  We need to extend the coax from where the radios were original kept to a new room.  Most of it will be above the drop ceiling, however a portion of the run will be going over hard-top, so that will prove interesting.  If you have an 8 ft. ladder it would be helpful.

What Makes A Good Volunteer?

Emergency telecommunication volunteers come from a wide variety of backgrounds and with
a range of skills and experience. The common attributes that all effective volunteers share are
a desire to help others without personal gain of any kind, the ability to work as a member of a
team, and to take direction from others. Emergency telecommunication volunteers need to be
able to think and act quickly, under the stress and pressure of an emergency.

You cannot help others when you are worried about those you love. Your own family should
always be your first priority. Adequate personal and family preparation will enable you to get
your own situation under control more quickly so that you are in a position to be of service to

Net Training - Principles of Disaster Communication

Taken from
Amateur Radio Emergency Service
Field Resources Manual

1.Keep transmissions to a minimum – In a disaster, crucial stations may be weak.  All other stations should remain silent unless they are called upon.  If you’re not sure you should transmit, don’t.

2. Monitor established disaster frequencies. Many A.R.E.S. localities and some geographical areas have established disaster frequencies where someone is always (or nearly always) monitoring for possible calls.

3. Avoid spreading rumors. During and after a disaster situation, especially on phone bands, you may hear almost anything.  Unfortunately, much misinformation is transmitted.  Rumors are started by expansion, deletion, amplification or modification of words, and by exaggeration or interpretation.  All addressed transmissions should be officially authenticated as to their source.  These transmissions should be repeated word for word, if at all, and only when specifically authorized.

4. Authenticate all messages.  Every message which purports to be of an official nature should be written and signed.  Whenever possible, amateurs should avoid initiating disaster or emergency traffic themselves.  We do the communicating; the agency officials we serve supply the content of the communications.

5. Strive for efficiency. Whatever happens in an emergency, you will find hysteria and some amateurs who are activated by the thought that they must be sleepless heroes.  Instead of operating your own station full time at the expense of your health and efficiency, it is much better to serve a shift at one of the best-located and best-equipped stations, suitable for the work at hand, manned by relief shifts of the best-qualified operators.  This reduces interference and secures well-operated stations.

6. Select the mode and band to suit the need. It is a characteristic of all amateurs to believe that their favorite mode and band is superior to all others.  However, the merits of a particular band or mode in a communications emergency should be evaluated impartially with a view to the appropriate use of bands and modes.  There is, of course, no alternative to using what happens to be available, but there are ways to optimize available communications.

7. Use all communications channels intelligently.  While the prime object of emergency communications is to save lives and property (anything else is incidental), Amateur Radio is a secondary communications means; normal channels are primary and should be used if available.  Emergency channels other than amateur which are available in the absence of amateur channels should be utilized without fear of favoritism in the interest of getting the message through.

8.  Don’t “broadcast.”  Some stations in an emergency situation have a tendency to emulate “broadcast” techniques.  While it is true that the general public may be listening, our transmissions are not and should not be made for that purpose.

9. NTS and ARES leadership coordination.  Within the disaster area itself, the ARES is primarily responsible for emergency communications support.  The first priority of those NTS operators who live in or near the disaster area is to make their expertise available to their Emergency Coordinator (EC) where and when needed.  For timely and effective response, this means that NTS operators should talk to their ECs before the time of need so that they will know how to best respond.

Net Training - Cross Band Repeaters

The following information is taken from “The ARRL Operating Manual for Radio Amateurs, 9th Edition.”
I was, recently, asked if I knew anything about CROSSBAND REPEATING.  If you have a dual band, dual-display mobile radio and a handheld radio you can set up your own repeated system.

Why do so?  There are several reasons.  My personal reason is as follows.  I have two separate radios installed in my vehicle.  One radio is a dual-band dual-display Kenwood, TM-V7 and one is a Motorola, Spectra, single band UHF radio.  My Motorola has a public address system with an external speaker, so I can hear the radio outside my vehicle.  The Kenwood does not.  There have been times when I was out of my vehicle and did not have a handheld radio with me, but I wanted to keep track of what was going on on-the-air.  I set my Kenwood as a repeater from 2 meter frequency to 70 centimeter frequency.  Any call that came in on 2 meters was repeated on the UHF and came out through the external radio speaker.  I could now hear what was happening and also hear if someone called me.

Let us say you want to operate your handheld radio, but you need the extra power of your mobile radio to hit a repeater.  For example, you’re on the lower level of a shopping mall with your handheld.  You can’t reach the local repeater from down there, but you can the repeater from your vehicle in the parking lot.  Again you repeat through your vehicle to the repeater and you have coverage from your handheld.

You may be in one of the hospitals and you have your handheld, but cannot reach the local repeater, but you can reach your vehicle in the parking lot…I think you get the idea.
Cross-band repeat operation in most mobile radios is very simple.  When the cross-band function is turned on, anything the radio hears on one band is retransmitted to the other.  When the signal stops the radio goes into receive on both bands and waits for the next signal, on either band, to repeat.  So down in the mall or down in city hall or down in the hospital, you transmit on UHF.  Your mobile hears its UHF received, and repeats you to the main repeater on VHF, flips itself around and repeats the main repeater back to you using the UHF transmitter.  Simple as this is, it can take a while to wrap your mind around the concept.

There are some problems that limit the utility of cross-band repeat.  The biggest problem is hang-time on the main repeater – the time after someone stops talking, but the repeater stays on the air, beeps, and finally drops.  On many repeaters that’s several seconds, and when two hams are in conversation, the repeater never drops until they are done.  It will automatically reset the time-out timer as each one un-keys their mike so it does not time-out.  Your cross-band repeater can’t tell the difference between a ham’s transmission through the repeater and the hang time afterwards.  It’s all just one long signal being received.  So, if you, down in city hall, are listening to two hams talk, you can’t break in until they’re done.  As long as they are talking, your mobile never stops sending the signal to you, and never listens for you. (Something else to keep in mind here is that your mobile is now transmitting a lot, and it is not designed for continuous transmission.  Keep it in low power.)

A repeater can be made “cross-band repeat friendly” by having a very short hang-time, or by specially designed CTCSS system.  If the repeater sends the tone only when a signal is on the input, and turns it off during the hang-time, your cross-band repeater can use the tone to know when to transmit and w2hen to shut off, allowing you to access the repeater between transmissions normally.  Or, if you can hear the main repeater directly on your handheld but just can’t get back to it, you do one-way cross-band repeat, from your handheld through the cross-band repeat, from your handheld through the cross-band mobile, but not back to your handheld.

A few notes of caution:  first, be careful in configuring your cross-band repeater.  Choose frequencies wisely – your coordination group may have identified band segments for cross-band repeat operation, so don’t just plunk down anywhere you want.  Do some research.  Guard the “local” side of your cross-band mobile with CTCSS or DCS.  If you don’t, and the squelch opens on your mobile, it will spew noise out to the main repeater.  Cross-band operation I particularly useful for emergency and public service event work, but a noise spewing, out of control cross-band mobile can render a vital repeater useless.

Second, maintain control.  The FCC rules require you be in control of the transmitter, but are not specific about how you do that.  If you can reach the vehicle in a few minutes from the inside of city hall, that’s probably good enough.  But don’t stop paying attention to it or leave the area.

Finally, you are required to ID both your mobile transmitter with your call sign.  How do you ID the transmitter that’s sending the main repeater signal back to you?  If you ID at the end of a transmission it goes out on the handheld and is repeated on the other frequency.  I don’t know many hams that talk for ten minutes, but you are to ID every ten minutes.

April 21st Drill - Recap

First off, hats off to all those that participated in our April 21st drill.  You all did great!  We were able to have a check in from every school in West Valley City which totaled 32 schools.  It took us about 80 min to complete and I felt things went pretty well.  I appreciate the input I also received during the drill and will see how best I can incorporate them in the future.

We also had the opportunity to work out of the City's new communications trailer and give it a proper shake down.  When doing these type of exercises you always find little things that need to be fixed which is the purpose of doing this.  I appreciate WVCFD for their willingness to bring out the trailer and allow us to use it.
