Hospital Drills in 2013

The San Joaquin County EMS Agency holds an emergency communications drill for hospitals and clinics at 1pm on the fourth Thursday of odd-numbered months. All licensed Amateurs are invited to check in and hear the kind of messages we might pass during a real emergency.

Dates in 2013 are:

  • 5/23
  • 7/25
  • 9/26
  • 11/28

The drill takes place on the 146.655 - PL 100.0 repeater. Please join us and participate.

Dear Reader:

This is my site and reflects my opinion. It is intended to offer ideas, examples and suggestions. It is not saying that I am right and you are wrong. This is a big world and EMCOMM is at least a little different in every locale. I am trying to discuss issues and uncover best practices. If you do things differently or have questions or comments, please share and help educate us all.

Q: Do Health & Welfare Messages Still Exist?

This is a question for the Amateur Radio EMCOMM community: Do hams still pass formal health & welfare message traffic? My sense is we do not, at least not on any large-scale basis, but maybe I am wrong. I care about this because I am writing training materials that need to touch on this.

Specifically, I’d like examples of health & welfare traffic gathered and sent on behalf of served agencies. How was it collected? For whom? Where did it go? How many messages were there? How was it delivered? Was it delivered?

I suspect there is some informal ham-generated messages on behalf of family and friends and done without an agency request. I’d like to know about that, too.

Please respond at n5fdl.com or by email.

Thank you.

5 Myths of the EMCOMM Net Control

Being net control is not what many people think it is. Net control is not all-powerful, nor it being net control especially glamorous. Yes, it has certain advantages, but there are clear disadvantages, too. This post is about how what many people think a net control is or does is not totally true. These are the myths of EMCOMM and public service event net control.

This is the first of what is likely to be a series of posts on the role played by net control operators in emergency and public service communication. I have been asked to prepare a presentation for net control wannabe’s and I’m using my blog to work out the content. Please feel free to comment and set me straight if the mood strikes you.

My comments should be taken as a very broad approach. There are few things of which I am absolutely certain, but one of them is that Amateur Radio and Emergency Management mostly play by local rules, which should be followed. If anything here is useful to you, please apply it however it works best where you live.

1. The Net Control Station is “In Charge”

This is the biggest and most important myth, because it’s what can get a new net control in trouble the fastest. If you think you are in charge, think again. Sure, in a directed net people are supposed to communicate through net control. And you may be moving people around, even giving orders.

Rare, however, is the circumstance where the net control is truly his or her own boss. Unless it is your incident or exercise and you are the incident commander as well as net control, you are working for someone else.

This may be a public safety incident commander (IC), a communications unit leader (COML) or “merely” the organizer of the bike ride your group is supporting. Almost always, a net control is working to facilitate someone else’s incident, exercise, bike ride, horseshoe toss, whatever.

There is almost always someone giving direction to net control, but often with little understanding of what is possible, what we do or how we do it. An important part of the net control’s job is translating someone else’s orders into actions the net members can take.

2. The Net Control Actually Controls the Net

Your net members are volunteers. If they follow your direction, it’s because they want to. Give them directions they don’t like and they may not follow them. Or may not be available the next time you need their help. Some groups are more committed and better disciplined than others, but net control must always remember that net members are not slaves and cannot be taken for granted.

3. Net Control does the Most Important Work

Check your ego at the door. It’s the members of the net that do the actual work. They are in the field, at fixed locations, perhaps mobile. They are out where things are happening, may happen or better not happen. They are the eyes and ears of the operation. You have the honor of talking to these great volunteers who are doing all the important work — probably out in the sun.

Net control’s job is primarily to support net members in getting the job done, responding to requests from above, assigning tasks to net members and reporting the result back to the requesting party. And variations on that theme.

4. The Net Control Station Works Alone

If you see a net control working alone, kill him. (Before he kills someone else). OK, a bit extreme, but a very serious point: If you are working an emergency net all by yourself, you are putting the net members and operation at risk.

Rand Paul filibustered for 13 hours before the call of nature arrived. You are unlikely to last as long. If you are all alone, you will probably have to leave the net from time to time. Bathroom, food, drinks, whatever, will draw you off the radio. That’s when four-out-of-five doctors predict something bad will happen and the net will go wonko while you are away. Don’t let that happen.

Smart net controls want at least one and maybe several other operators — who needn’t be great net controls themselves — somewhere within earshot. One of these people should be your logger and extra set of ears.

Logging is a critical task that many people — sometimes including me — don’t pay enough attention to. If you get in the habit of keeping good logs when they aren’t really necessary, it won’t be a chore when you really need them.

Net control locations can be noisy and you may need to keep an ear on multiple radios or channels, if only so you know what else is going on around you. That’s when a skilled assistant can be a real help. Note that I said “skilled.” Find people who can keep track of what’s happening on multiple public safety scanners at the same time and make them your extra ears at net control during an event or incident.

You need to be careful, however, about having too many hangers-on at net control. Ever notice how many times people who are supposed to be in the field land at net control — and stay? Or that “sag” vehicles at cycling events can all end up at the same place? One of the jobs of the assistants at net control is to send these people back where they belong, early and often.

5. Anybody Can Be a Net Control Station

Being net control does not require the ability to fly faster than a speeding bullet or even have more power than a locomotive. It does, however, require a variety of skills that not everyone has. The reason I mention this myth is in honor of groups who rotate their net control duties among all the group’s members.

That is not a good thing if it gives people the false sense that they are actually good net controls, when they probably are not. Running the weekly club net requires only a minor subset of what is required to run emergency or public safety communications.

Regardless of how you run day-to-day operations, designate your “real incident” net controls in advance and make sure everyone knows who they are.

5 Leadership Mistakes You Don't Want To Make (That I Have)

Let me start by admitting I’ve done or been close to all of these or something very much like them. So, if I am calling anyone out, I’m at the head of the line. Still, I’d like to think I’ve learned.

1. Not having a strong second-in-command. This was no-one’s fault and we knew we were pushing it, but an APRS exercise melted after the organizer was called away for a family emergency. Not a big deal, families come first. But, you can bet the next time we will be better organized with a deputy designed and trained to take over. (Explaining way we did the small exercise described here recently).

2. Never leave a net control alone. It really bugs me when an event net control says they will be away from the radio for a few minutes. What happens if there is an emergency while the net control is getting a Coke? If we always kept two or three people at net control (as I now do), that will not become an issue. Someone would always be on the radio

3. Lack of understanding the mission: I don’t care how much you love your charity events, the real reason we are there is to protect the public and event participants. That doesn’t mean we don’t work closely with the organizer to help the event be a success, but we are really there to help the sick and injured, the cyclist stuck out on the course, the lost kid and her parents, etc. Being ready when something bad happens — and it will — is what we are supposed to be about. Everything else is a nice add-on. Think EMCOMM first.

4. Don’t send volunteers away. You should NEVER tell a volunteer you don’t need him or her working your event. Especially when they have bothered to show up. OK, there may be the very rare person you don’t want, period. But, you can probably find a task for them anyway. If a volunteer needs/wants to bail for some reason, that’s one thing. But, telling someone who took the time to show up that there is no job for them only demonstrates a lack of creativity on your part. Volunteers who leave unhappy are volunteers we never see again.

5. Deal with the “Peter Principle,” which holds that people rise to the level of their incompetence. Clubs need to find a way to insure their best players move forward and the less-talented are given supporting roles. One member, who happens to be a nice guy but lacks talent/training/IQ/whatever, shouldn’t be allowed to hold everyone back. I am not, however, sure of the best way to deal with this., though I have seen it in many clubs and heard about it in many more. Ideas sought.

Bonus: 6. If you are organizing ham communications at someone else’s event and you are just not getting the support and cooperation you need, seriously consider bailing out early. Sometimes, everything comes together because you have enough control to solve problems. Sometimes, the person above you never gets onboard and their lack of planning/communication messes things up. In that case, let the person who isn’t cooperating solve their own problems — but bail out with enough notice for an alternate plan to be hatched (by someone else).

I’ve been personally involved in at least one of each of these six items. I hope I’ve learned from them and you may learn from me and avoid getting burned yourself.

Tell me about your issues and mistakes you’ve seen. Comment below.

A Morning of APRS EMCOMM Fun in Tracy

N6TCE’s portable digipeaterOn Saturday, Bob N6TCY, Brian N6ZZY and myself spent the morning driving around Tracy and San Joaquin county testing APRS coverage from our portable digipeaters and an iGate. This is a report on what we think we accomplished and how we plan to proceed. In an emergency, this is the type of installation we plan to use.

Vague map for coverage — click for larger imageWe were doing the testing on the NCPA alternate APRS channel, 144.410, using our own digipeaters and iGate, set up just for the test.

APRS, for new hams, is a system for transmitting location and other information over Amateur Radio. Digipeaters — sort of digital repeaters — are to APRS the same range-extenders that analog repeaters are to voice transmissions. iGates receive packets and post them to the Internet.

One of the digis was a Kenwood TH-D72 talkie, attached to a small beam, located at the same site as the 146.655 repeater. This is a location at about 1,800 feet (as I remember) in the Altamont Hills. The beam points toward Stockton, so it is aimed a bit north of Tracy.

Portable digipeater — FT-1500, KPC3+ and a batteryThe mobile digi was a Yaesu FT-1500, Kantronics KPC3+, battery-powered and connected to an Arrow Antenna j-pole at about 25 feet. Bob located this digi in South Tracy, along I-580, with a commanding view of the valley. (About 300 feet in elevation).

The iGate was located at Brian’s house in Tracy, and gatewayed our RF location reports into the APRS Internet data feed. It was not be apparent to Internet users that we were not on 144.390, the national APRS channel.

Once the infrastructure was set-up, Brian and I drove around using at least two APRS radios at all times. His was a Yaesu VX-8 talkie connected to an external antenna. I used an old Kenwood TH-D7A talkie, connected to a quarter-wave mag mount antenna. We both also had Yaesu FTM-350 mobile radios shooting packets at full-power.

We are still looking over the packet logs to see what was heard by which digi from where, so that will be the subject of an update in the future.

N6ZZY and N6TCE adjust radios in the jeepHere is what we think we learned:

1. A handful of users (in this case, four radios and two digis) can create an awful lot of traffic if frequent location fixes are required.

2. The iGate, connected to an outdoor antenna on Brian’s two-story house, worked great and did a fine job of making our position reports available to Internet APRS clients. It was nice to have the iGate beacon occasionally so we knew we could hear it.

3. We had a few reports from the Internet seemingly leak through the iGate and get transmitted on RF. Need to understand why that happened, but it was not a severe problem.

4. Having two digipeaters definitely improved our range, but we have to figure out which worked best where. It appears that within 8-10 miles, the local digi on I-580 picked up most of the packets, with the Altamont digi picking us up from as far as 25 miles on 5 watts.

5. We realized that none of us know as much about APRS or the settings on our radios to be really comfortable doing an exercise like this, but it was a start. Please be gentle in your comments.

6. Thank you, Northern California Packet Association, for creating the “alternate” APRS channel intended for situations where users need a quiet channel and are willing to bring their own infrastructure to get it. It is hoped that any use of the channel will be temporary in nature and permanent infrastructure will be limited. We don’t need another mess like 144.390.

We feel like we proved that the current configuration (two digis, one iGate) will work well across the Tracy area. Log analysis will tell us how well the I-580 digi worked with 5-watt signals (out to what distance?). The iGate did a good job of making us appear on Internet clients.

Speaking of which, if you have a smartphone and intact data network, apps like OpenAPRS (iOS) and APRSdroid (Android) are probably better ways to get your packets into the Internet feed than RF. However, packets sent over the Internet are generally only visible on other Internet clients. Your mobile radio operators will never see the packets generated by the smartphones. It also means that net control and others must use APRS apps and an Internet connection to see everyone’s location.

Depending on the circumstances, that may or may not pose a problem. More in a future post as we learn more.

Updated Stockton Repeater

The 147.210 + 114.8 repeater is back on the air, but suffers from occasional self-generated feedback. Keying the repeater eventually stops this and we expect a fix soon.

This repeater is intended to provide HT coverage in Stockton.

The pic shows the repeater in its cabinet. The "blade" is a pair of Motorola mobiles, custom mounted by Ron N6GKJ, who built the system.
