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.

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.

W3HC SK
Unfortunately, a few days after Carl W3HC (ex-W3HCW) celebrated his 100th birthday, he fell ill, declined rapidly, and passed away. We can’t complain as he lived a full life and got to enjoy a beer at his birthday party.

Photo credit: Karen Vibert-Kennedy, Williamsport Sun Gazette
Carl was an avid photographer all his life. The Williamsport Sun Gazette featured an article and video on his time in Berlin during World War II, taking photographs. While in a bombed out home, he found a roll of film which he took home and later developed. He was shocked to discover the photos were taken by a German photographer and even included pictures of Himler, who was the #2 in Germany at the time. Many of his photos are featured on his Flickr site.
I owe my grandfather a lot of gratitude as he’s the one who got me into amateur radio which led to me getting my first two jobs in wireless and communications, and laid the foundation for a rather successful career. I continue to be active in amateur radio, with QRP, field operation, circuit design, open source software development, and homebrewing equipment being my favorite activities.
Carl was first licensed in 1956 as WN3HCW, back when Novice calls had the WN prefix. After upgrading to Technician, the FCC dropped the N and he became W3HCW. Later in the 90s when he upgraded to Extra he shortened his call to W3HC. During my time with him as a youngster and teenager, he operated nearly all HF phone and enjoyed DXing, but he also did a lot of 6 meter AM work in the 60s. He operated theW3HCW QSL Fund which funded QSL cards for DX stations, and he was a QSL manager for about 130 stations over the years.

Cheryl’s Recipe Corner!
Skillet Chicken Bulgogi
Description
This bulgogi chicken is a quick-and-easy, but very tasty, meal. You can substitute the chicken with beef or pork for variety. It only takes 30 minutes with very few dirty dishes! Serve over rice.
Ingredients
1/4 cup chopped onion
5 tablespoons soy sauce
2 ½ tablespoons brown sugar
2 tablespoons minced garlic
2 tablespoons sesame oil
1 tablespoon sesame seeds
1/2 teaspoon cayenne
salt and ground black pepper to taste
1 pound skinless, boneless chicken breasts, cut into thin strips
Directions
Whisk onion, soy sauce, brown sugar, garlic, sesame oil, sesame seeds, cayenne pepper, salt, and black pepper together in a bowl until marinade is smooth. Cook and stir chicken and marinade together in a large skillet over medium-high heat until chicken is cooked through, about 15 minutes. Notes: You can substitute peanut oil for the sesame oil if desired. Add vegetables if you wish; carrot straws and sliced mushrooms are delicious add-ins. For a little more bite, use a peppercorn medley grinder instead of black pepper.
Cheryl’s Mixed Drink Corner
Key Lime Mojitos
Description
If you have an abundance of Key limes after making a classic Key lime pie, use some up to make this refreshing summer cocktail. The tart juice of Key limes makes the mojito a bit sharper and more citrusy, and the cream makes it taste like a creamy slice of Key lime pie. You’ll need a simple syrup for this cocktail, which is super-easy to make if you don’t want to buy one. You can even add some mint leaves in with it to make the mint flavor stronger.
Ingredients
1/4 c. crushed graham crackers
3 tbsp. simple syrup, plus more for glass
1/4 c. fresh mint leaves, plus more for serving
3 tbsp. fresh Key lime juice
4 oz. white rum
1 tbsp. heavy cream
Key lime rounds, for serving
Directions
Place crackers on a plate. Pour simple syrup onto another plate. Dip rims of glasses into simple syrup, then into crackers. In a cocktail shaker, muddle mint and lime juice. Fill shaker with ice and add rum, cream, and simple syrup. Vigorously shake until outside of shaker is very frosty, about 20 seconds. Fill glasses with ice and strain mojito into prepared glasses. Garnish with more mint and a Key lime round.

It’s a new take on Laphroaig that plays to our strengths – welcoming friends old and new.

Hoptimization - Brothers Craft Brewing - Harrisonburg, VA
What’s a craft brewery to do when all the “typical” IPA hops are gone? Innovate of course, just like craft breweries always have. Hoptimization uses big, bold, bitter hops to get a clean citrusy flavor you’ll love and the bitter bite that you crave. Step away from typical and try something new.
