The Eruption of Mt. St. Helens

Remembering the amateur radio
account by Gerry Martin W7WFP

On Sunday, March 27, 1980, a series of volcanic explosions and pyroclastic flows began at Mount St. Helens in Skamania County, Washington, United States. A series of phreatic blasts occurred from the summit and escalated until a major explosive eruption took place 44 years ago today, on Sunday, May 18, 1980, at 8:32 am. The eruption, which had a volcanic explosivity index of 5, was the first to occur in the contiguous United States since the much smaller 1915 eruption of Lassen Peak in California. It has often been declared the most disastrous volcanic eruption in U.S. history.


Mt. St. Helens one day before the eruption and 4 months afterwards



The Role of Amateur Radio - Gerry Martin W7WFP

Gerry, 64, was a volunteer ham radio operator who was monitoring the mountain for the Radio Amateur Civil Emergency Service. The day before the eruption, he drove his motor home onto a ridge a couple miles north and slightly higher than the geologists’ observation post. When the mountain erupted, he reported to the other ham operators monitoring the volcano, “Gentlemen, the camper and car that’s sitting over to the south of me is covered. It’s going to hit me, too.” As with Dave Johnston, no trace of Martin or his motor home was ever found. The audio account of his observations as the mountain erupted is in an Oregon Public Broadcasting article. The article also has a link to a video of the event.

The eruption claimed the lives of 57 people, mostly through the effects of ash asphyxiation.

Restricted putting up an antenna?

 Hide it in your holiday lights!

For all their supposed benefits, homeowner’s associations (HOAs) have a reputation of quickly turning otherwise quaint neighborhoods into a sort of Stanford prison experiment, as those who get even the slightest amount of power often abuse it. Arbitrary rules and enforcement abound about house color, landscaping, parking, and if you’ve ever operated a radio, antennas. While the FCC (at least as far as the US is concerned) does say that HOAs aren’t permitted to restrict the use of antennas, if you don’t want to get on anyone’s bad side you’ll want to put up an antenna like this one which is disguised as a set of HOA-friendly holiday lights.

For this build, a long wire is hidden along with a strand of otherwise plain-looking lights. While this might seem straightforward at first, there are a few things that need to be changed on the lighting string in order to make both the antenna and the disguise work. First, the leads on each bulb were removed to to prevent any coupling from the antenna into the lighting string. Clipping the leads turns what is essentially a long wire that might resonate with the antenna’s frequency into many short sections of wire which won’t have this problem. This also solves the problem of accidentally illuminating any bulbs when transmitting, as the RF energy from the antenna could otherwise transfer into the lighting string and draw attention from the aforementioned HOA.

Tests of this antenna seemed to show surprising promise while it was on the ground, but when the string and antenna was attached to the roof fascia the performance dropped slightly, presumably because of either the metal drip edge or the gutters. Still, the antenna’s creator [Bob] aka [HOA Ham] had excellent success with this, making clear contacts with other ham radio operators hundreds of miles away. We’ve shared another of [Bob]’s HOA-friendly builds below as well which hides the HF antenna in the roof’s ridge vent, and if you’re looking for other interesting antenna builds take a look at this one which uses a unique transformer to get wide-band performance out of an otherwise short HF antenna.

SEPAR Mobile Cruise-In

 Come show us yours... 

Many Amateur Radio licensees have home stations where the hobby is practiced for fun, contacting similar stations all over the globe, but the hobby has a serious side as well. We provide emergency communications where all other systems, such as cell phones or even radio towers fail. Many of us have mobile stations (in compliance with distracted driving regulations) that permit us to operate wherever and whenever. Mobile Amateur Radio is not restricted to cars and trucks but bicycles, even pedestrians and equestrians. This type of broad-based community availability requires no commercial infrastructure, hence the slogan: “ Amateur Radio works when all else fails”. This has been shown time and again all over the world.

SEPAR would like to host a first ever event of its kind locally. We have a commitment from the Surrey Fire Service and I expect that support from our contacts at the Surrey RCMP (or Surrey Police Service)  to judge the entries.  Prizes will be awarded for the neatest installation and the most bands covered.

The idea for this local event originated with the Portage County Amateur Radio Service (PCARS), a Wisconsin group who have been doing the Mobile Cruise-In for twelve consecutive years.  Their turnout varies with the weather, but in past years they've had 50 or more entries. In addition to the entrants and Amateur Radio spectators, we welcome members of the public to stop by and check out the goings on. They say that it's a great way to generate some exposure for Amateur Radio and our emergency programs.

We appreciate the support of the A&W restaurant at that location but, if you are not an A&W fan, there are several other refreshment options adjoining the same large parking lot.

So polish up your mobile rig, dust off your Grab ‘n Go kit and come show it off at  the ‘Cruise-In’

Field Day 2022 (Sunday) Update

 

It's a wrap!

Well, its all over for another year. A solar storm just before the weekend significantly affected propagation but we did make a substantial number of contacts, including on VHF.



It struck me how much Field Day has changed over the years. Despite the poor early 1985 photos, here are some of the comparisons...

No more paper logging and SDR transceivers


Antennas for every purpose and mode
Here Moon-Bounce, our 'BigFoot' and Satellites


That sense of accomplishment and
pride in the hobby remains the same

If you would like to see video of  SARC Field Days of the 1980's, and those more recent, visit our YouTube Channel.

So that's it for another Field Day. The RAC Canada Day contest is just around the corner though. This year SARC-SEPAR is operating as VE7RAC. See you on the bands.

There will be additional coverage and photos in the next Communicator e-Zine on July 1st.

North American Emergency Communications Exercise June 26-27


 “Who ya’ gonna call? Radio Hams!”

Emergency Communications Exercise June 26-27

Despite the Internet, cell phones, email and modern communications, every year whole regions find themselves in the dark, or worse. Tornadoes, earthquakes, fires, storms, landslides, ice and even the occasional cutting of cables leave people without the means to communicate. In these cases, for over one-hundred years the one consistent service that has never failed has been Amateur Radio. These federally certified radio operators, often called “hams” provide backup communications for everything from community events to local Emergency Operations Centres.  Surrey “hams” will join with thousands of other Amateur Radio operators testing their emergency capabilities this weekend. 


In recent years, the news has been full of reports of ham radio operators providing critical communications during unexpected emergencies around the globe. When communications become overloaded or fail, Amateur Radio’s people are often the first to provide rescuers with critical information and communications. On the weekend of June 26-27, Surrey’s ham radio operators will join with thousands of similar groups and individuals throughout Canada and the United States, using a variety of voice and data techniques in an annual exercise of emergency communications capabilities known as “Field Day”. 

This annual event is recognized throughout North America, and locally through a civic proclamation by Surrey City Council designating June 20-26 as “Amateur Radio Week”. Self-sufficiency is the key. Using only emergency power, ham operators will construct emergency stations in parks, parking lots, schoolyards and backyards throughout the continent and operate without commercial infrastructure for the duration of the 24-hour exercise. Their slogan, "When All Else Fails, Ham Radio Works” is more than just words to the hams, as they prove they can send messages in many forms without the use of phone systems, the internet or any other infrastructure that can be compromised in a crisis. More than 38,000 amateur radio operators across the continent participated in last year's event.  

Surrey Fire Service Assistant Chief Shelley Morris, who coordinates emergency response for the City of Surrey adds: “Amateur Radio plays an integral part in emergency preparedness during any major disaster for the city. They train extensively and they operate a communications room out of our Number One fire hall. They play a very important role keeping backup communications for the operations centre up and running during a major disaster and providing enhanced life safety for the citizens of Surrey.”

Gord Kirk, coordinator for the Surrey Emergency Program Amateur Radio (SEPAR) group highlighted the value of Amateur Radio in its flexibility. “Amateur Radio is not centralized. There is no single point of failure; it does not rely on the Internet, a power utility or a communications company, cell towers or other infrastructure to provide service. It works when nothing else is available.  In partnership with the Surrey Amateur Radio Communications (SARC) group we provide knowledgeable people, sophisticated equipment, and thousands of volunteer hours annually to support the City of Surrey Emergency Program. Once set up, we need nothing between us but air.” 

The SARC group supports SEPAR by providing equipment, infrastructure and technical assistance. SARC President John Brodie commented that: “We are fortunate that what hams enjoy as a technically-challenging hobby can make a vitally important contribution to emergency communication during a crisis”.

The Surrey team placed first in their Canadian category in recent years. The event takes place from 11am Saturday, June 26th to 11am Sunday, June 27th.  While this is normally a public affair, due to current COVID restrictions there are no public demonstrations, although in past years the technology shown has included contact with astronauts orbiting in the International Space Station. This year, smaller stations and individuals will participate from several neighbourhoods in Surrey.

Amateur Radio is growing in Canada and requests for training have increased significantly since COVID restrictions started. Hams socialize daily through radio contacts and the basic equipment to communicate worldwide can be purchased for less than $50. You no longer require Morse code, although it is still used in the hobby. Amateur Radio is practiced as a hobby, as a sport, and as a reliable means of communications by outdoors enthusiasts and others where cellular telephone towers do not exist. There are now over 30,000 Amateur Radio licensees in Canada, and more than 2.5 million around the world. Through the Amateur Radio emergency services program, ham volunteers provide both emergency communications for thousands of provincial and local emergency response agencies and non-emergency community services too, all for free.

In a nutshell:

Surrey Field Day Overview

SUMMARY: An emergency preparedness exercise to establish long distance communications capabilities in support of the City of Surrey Emergency Program. Surrey Amateur Radio operators will set up a field station simulating emergency conditions, without using commercial services, to contact thousands of other hams throughout North America and beyond, in the continent’s largest ham radio on-air event. This team placed first in their Canadian category for Field Day 2018. They will be looking to better their score in 2022 after COVID prevented team participation for the past two years; the public is invited to observe contest operations, see ham radio’s new capabilities, experience a moon-bounce contact, view a satellite contact and learn how to obtain their own Industry Canada radio certification.

WHO: Federally certified Amateur Radio Operators supporting the City of Surrey Emergency Program.

WHAT: Hams will set up and operate field radio stations to contact other hams throughout Canada, the US and beyond over 24 hours using a variety of modes including voice radio, Morse code, satellites, and digital. The objective is to see who can make the largest number of contacts during the exercise period.

WHERE: The Surrey Emergency Program facility at 5756 142 Street, Surrey BC.

WHEN: Operations 11 am Saturday, June 25 to 11 am Sunday June 26.

WHY: Participation in the amateur radio community Field Day. Amateur Radio operators emergency communication skills under adverse conditions with generators, battery-powered equipment and portable antennas.

Special awards are given for “alternative” power sources such as solar, wind and other means. Field Day is a competition as well as a “trial run” for emergency communication skills used during disaster situations

Our Amateur Radio volunteers will accommodate photo opportunities, interviews, and profiles of the activities of both our participants in an important national Amateur Radio event and their role in the Surrey Emergency Program. There is an opportunity to see all Amateur Radio communication modes in action, including voice, Morse code, satellite, and digital. There will be opportunities for the public to participate, including activities geared toward children.

There will be opportunities to explore the relationship to other facets of the Surrey Emergency Program.

Sponsors and participants:

  • ·         Surrey Emergency Program Amateur Radio
  • ·         Surrey Amateur Radio Communications
  • ·         Surrey Fire Service
  • ·         Surrey Emergency Program

SARC-SEPAR November 10 Presentation on DMR

 Here is a guide to getting started on DMR

DMR stands for Digital Mobile Radio and is a European-developed international standard of digital radio. This new and versatile technology covers voice and data transmissions, along with conformance testing. It is an affordable digital solution to analog radio.

The only drawback is programming, which is more complex than standard amateur radio. DMR requires a 'codeplug' which is a file containing program information. With most analog ham radios you can convert a DMR code plug from one radio brand to another, using CHiRP for example. As mentioned during the presentation, every manufacturer seems to roll their own software, thus ensuring different nomenclature, and organization of their dialog boxes.

Its not for the faint of heart or for the beginner, so its best to consult someone in your area who may have a codeplug ready to go. For us that resource is Doug Pattengale VE7CQT, who gave an excellent PowerPoint presentation on the subject to a combined Zoom audience of SARC and SEPAR members. 

According to Doug, some of the worst radios don't include the ability to fully export or import the code plug elements so that tools like spread sheets can be used for bulk editing. There are tools 'out there' that facilitate this conversion from one proprietary software to another. For free! Have a look at this tool as it handles the TYT MD UV380 or 390 model in question. 

Doug has used it to convert an AnyTone code plug in the past, and he reports that its amazingly powerful and convenient. Once you get to know how it works, it can do in a few minutes what would take hours of work to manipulate in a spread sheet. An added benefit is that it compensates for missing functionality like sorting, re-ordering and cut / paste that the native CPS software lacks.

- this is a stand alone .exe file. You just drop it into a folder and run it. No hidden files, overhead, install or uninstall. Just delete it, and its gone.

Another Amateur Radio Contribution!

...said that it will revolutionize communications 

In a radical new development, Horace Blink MY2EAR has developed a new multi-band transceiver that can tune both upper and lower sidebands simultaneously. 



Horace is shown in a local park demonstrating the device and the 360 degree rotatable platform on which it is built. He told ‘The Communicator’ that the next step before large scale production is finding a method to use it indoors as he has experienced numbness in his extremities during foul weather use.

GMRS in Canada

There are major differences from US regulations 

Following up on a recent blog post by Bob Witte K0NR [https://www.k0nr.com/wordpress/] with the Canadian perspective.

There are big differences in GMRS rules between the US and Canada. If you understand the rules, you’ll  understand what you need to look for when purchasing GMRS radios, and you’ll understand what channels to use to get better range. And you’ll understand why you could get in trouble for using some US radios that are not approved for use in Canada – and vice versa.


Radios must be approved in the country of usage

Every GMRS radio has to be approved by the authorities of the country where you will be using the radio –  Industry Canada (IC) and the FCC in the US. There are also rules for usage. If the radio does not have an IC number, it’s not approved for use in Canada. If the radio does not have an FCC number, it’s not approved for use in the US.

Industry Canada has a lot of information here.

GMRS – FRS with more channels, and *maybe* more power

GMRS is an evolution of FRS that is compatible with older FRS radios on the FRS channels.  But there are significant differences between Canada and US regulations.

Licensing, power limits, antennas and repeaters

In Canada, GMRS users do not require a  license. In the US, radios above 0.5 watt require a GMRS license. In Canada, you’re limited to 2 watts power on the GMRS and combined GMRS/FRS channels, and 0.5 watts on the GMRS channels. In the US, if you have a license, you can go to 5 watts on the GMRS/FRS and GMRS channels.

Repeaters. There is no provision for legal usage of GMRS repeaters in Canada. In the US, licensed users can us GMRS repeaters and GRMS radios with repeater capability.

Antenna. In Canada, the antenna must be fixed on the radio. It cannot be removed, and it is illegal to replace or modify it. In the US, licensed users can change the antenna.

What’s the range of my radio? How is it affected by power?

Most of the radios you buy in big box stores in Canada and the US are designed to be legal for unlicensed usage in both US and Canada – which means you will be limited to 0.5 watts, a quarter of the power you’re allowed to use in Canada. The ranges they advertise are generally ridiculous, varying from 20 km to 80 km (50 miles).

Finding the power rating for the radio is not always simple. Most manufacturers don’t tell you. We’ve checked the packaging, manuals and web sites for the two biggest manufacturers, and it was either not there or very difficult to find. We’ve never seen a radio rated for the full 2 watt maximum. The closest we’ve seen is 1.92 watts, advertised with a 80 km/50 mile range. We’ve seen 1.6 watt advertised with a 50 km range. So everything is approximate.

Another hint is the batteries. A 0.5 watt radio might have a battery compartment for 3 x AAA batteries. A radio with 1 watt, 1.5 watt or just under 2 watts might have 3 or 4 AA batteries to handle the extra load.
