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.

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.

 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.

 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’
