Welcome to 2017

2016 has come and gone. It was a busy year for hurricanes, wild fires, and tornados, many of which had the good sense to stay out of the county. Sadly, Mother Nature felt we needed more practice with snow preparations and decided that a couple of feet would be a good place to start. As we know it only takes a few inches to throw the region into a tizzy, and a couple of feet immobilized us for several days. Around the world, they not only had to deal with unusual weather, but man-made attacks as well.

2017 has arrived. We can hope that the winter of 2016 is not repeated. And we can hope that Mother Nature takes a break. But we must always be vigilant. As we enter 2017, we should take stock of our gear and review our plans. At the very least, take a look at your go-kit. Clothes tend to shrink when they are not worn regularly, and sunscreen does age out over time.

I have already updated the training plan for 2017. If you have not already got the big four under your belt (IS–700, IS–800, IS–100, IS–200), please take a moment to do so. If you have not already sent me your certification for passing, please do so as well so I have a record. I will be working through making additions and subtractions on the site as I get time. I have already added the new DHS widget that alerts us to updates and bulletins. I will also be trying to convert the quick reference guide into something you can put on your mobile device in ebook format, as well as something you can print out and carry in your go-kit.

We have several AEC positions open. If you would like to volunteer, please drop me a note. I am also looking for someone who can attend the monthly Emergency Manager’s meeting for me as I will not be able to attend as regularly as I have in the past.

Our friend, Pat Collins has retired from Emergency Management so there will likely be some small changes to the way Emergency Management is run in Prince William County. As I know more, I will let you know. At this point there is a search on for Pat’s replacement and I am sure they will find the best person for the job.

Our next meeting is Saturday, January 21, 2017 at 0900 at the EOC. As we normally do at the first meeting we will review the year past, look at the year to come, review the action plan, and update photos and contact information. We will also have a go-kit show and tell. There are a number of really good ideas out there and the cold winter months are a good opportunity to make modifications and ponder what others are doing.

If you would like to write an article for the Cadre, please let me know and I will be happy to give you a by-line. If you have pictures, please drop them my way so I can include them in the updates. And I will try to do better at posting in 2017 as well.

May you all have a wonderful 2017!

Welcome to the summer

With Memorial Day behind us, it is time to turn our attention to the summer. And we have seen a number of seasons where every other day was a sever storm. We have seen summer seasons where we barely got enough rain to tamp down the dust.

Today is the “second day” of summer and our friends at the National Weather Service predicts:

A FEW THUNDERSTORMS COULD PRODUCE DAMAGING WIND GUSTS AND LARGE HAIL LATE THIS AFTERNOON AND EVENING.

So the weather is already heating up.  Which leads me to the next date on the calendar – the start of hurricane season, which is June 1.

Depending on who you listen too, this season is expected to be quiet, sort of. Estimates are for 8-13 named storms, with only a pair of major hurricanes predicted. Compare this too 2013 where we had 14 reported storms and only two hurricanes (Sandy was in 2012, in case your memory is a sketchy as mine is).

So take advantage of the Virginia Tax free week this week (May 25 – May 31) to stock up on your hurricane and other disaster supplies.  You might also want to take a moment to review your antennas and tower supports and check your batteries.

 

Outbrief – 15 Feb 2015 Digital Workshop

On Saturday, February 14, 2014, the Digital Working Group met along with some other interested parties to discuss the current state of the digital technologies, as well as  try and find a road map for implementation within the PWCARES framework.  After introductions, we went through some presentations.

The Presentations
Rick, KJ4ZIH
  • Evolution from a discussion about “is there a role” for digital in ARES to  clearly there is, especially the farther west in the US you go.
  • Rick has issues getting from his home in Haymarket getting to the repeaters (WWI/OHV) on voice
  • EOC is currently VHF/UHF oriented
  • Two parts of the story – the tools (FLx) and how the PA group is using them (NBEMS)
  • Rick went the route of the SignaLink, but there is software that can do the same thing with your built in sound cards (mostly inexpensive)
  • Similar to a fax machine over a telephone line – stuck pig sounds
  • Multiple ways to move the noise – usually mic and speaker, with the right cables to make the connection

NBEMS

  • Ran through the NBEMS presentation
  • Digital is accurate in the information being transmitted
  • FEC in a number of them protocols
  • Served agencies are moving along the digital message paths
  • NBEMS is an application of the FLx programs
  • Flamp – broadcast message to all
  • Open Source, multi-platform
  • Fldigi – encoder/decoder, with multiple codex
  • Sometimes you need to tweak the time calibration of your soundcard
  • MT-63 is robust, quick, FEC, used by MARS, resistant to noise
  • Good for increased distance performance
  • Olivia is preferred on HF.  Sounds like a flute in the air. Stands out
  • Flmsg is pre-formatted, good fill in the blank ability
  • Text based, self-limiting to 3KB files, with a 3 minute limit for transmission
Derek, KV4SH
HSMM-MESH/Broadband
  • High-speed Mobile Mesh
  • Now called “Broadband hamnet”
  • Autoconfiguation fault tolerant ham radio coverage (part 15/part 97)
  • Because it is mess, it it multipath
  • High bandwidth
  • Transmits IP
  • Not limited by size of file
  • upto 150mb/sec depending on quality
  • Need to flash your router with a new image, configure, put on the air
  • Infrastructure based set up
  • There is the ability to get the hook up on to the Internet…there are issues with doing this
  • LinkSys, Ubuiquiti brand (www.ubnt.com)
  • Under 1 watt of power out of the repeater
  • Until you boost power, you are covered by part 15. Once you boost, you fall into part 97
  • Under part 97, no encryption, no WPA, no SSL/HTTPS/Encrypted chat
  • Coverage up to 10 miles but realistically, much more reduced
  • Emcomm – videos, large images, web cams
  • A discussion of the nuts and bolts of Internet vs Mesh set ups – ssid/esid vs IP address

David, KG4GIY

  • David reviewed the packet and WinLink
  • Packet is still a viable technology, but with a high learning curve.
  • Some masking is done by Outpost, a Windows-based piece of software.
  • Store and forward as well as direct connect. Also has the ability to hopscotch from node-to-node to improve connectivity.
  • Heavy infrastructure requirement, most packet nodes are no longer active.
  • WinLink is a long running, Windows-based message service.
  • Many have had success with it.

The Direction

After the presentations, we made some decisions. To wit:

OS: Windows (for now)

Mode: Ad Hoc

Band: VHF/UHF (for now)

With that as the preconception, the FLx stack of programs makes the most sense to implement. So:

OpMode: MT-63 2KL (2000L)

Freq: 146.475 (ARES VHF 2)

The Concept of Operations

At this point, digital messages are being utilized in experimental mode. While it is desirable to have a digital node at each location, until we are completely comfortable with operation, it may not yet be possible.

Further, these are the identified (but not exclusive) types of messages that could be passed by digital methods.

  1. Bulletins. These are messages that are sent out from NCS regarding the state of the operation, active locations, operational period data, weather updates, etc. that are necessary for all stations but could utilized excessive bandwidth on voice.
  2. POD Supply lists. These are lists that may include equipment and supplies needed at a Point of Distribution, either basics or medicinals.
  3. Low priority messages. These are messages that would take up unnecessary bandwidth on voice but still need to be passed.

While these are not all the types of messages that can, or could be sent by digital, it is a good start.

While we are working through the process and procedures, there are some additional issues we need to keep in the back of our minds.

  • Printers? What is the need for being able to print out these digital messages? Do we need to arrange for access to printers? What sort?
  • Directed Net? Does digital operations require a directed net? How would that operate?
  • Time segments? Would it make more sense to have a time slice management plan instead of a directed net. For example, in any 15 minute segment, the first x period is reserved for priority or emergency traffic, the rest of the period is a free for all?
  • Can fldigi be set to auto select operational mode? If so how so?

Finally, there was a decision to try and set up smaller hands on working groups to configure and test configurations before we take it to the field. There also needs to be a separate effort to create a quick reference guide. This can be managed via the digital list or this site.  If someone would like to volunteer to host a working group, please identify yourself and we will get it on the calendar.
