In Loving Memory of Donald Leslie “Donnie” Heide
1946 – 2025
Donald Leslie “Donnie” Heide, age 78, passed away peacefully on April 5, 2025, in Helena, Montana, after a courageous and tough battle with cancer.
Born in Yreka, California, Donnie was raised on a working cattle ranch, where his boundless curiosity and love of learning first took root. From a young age, he was captivated by how things worked—an interest sparked when, at age 10, his father gave him a soldering iron. That gift opened the door to a lifelong passion for electronics, invention, and mechanical exploration. Some of his earliest creations were practical, while others were more playful in nature, reflecting his enduring sense of humor.
Growing up, Don and his sisters were actively involved in 4-H and other activities. During high school, he cultivated a meaningful mentorship with teacher Al Kiep—an influential friendship that would remain steadfast throughout Don’s life. Though he couldn’t attend the after-school Amateur Radio Club due to the distance from the ranch, amateur radio would become a lifelong pursuit and a cornerstone of his identity.
After graduating from Etna Union High School in 1964, Don earned an Associate of Arts degree in Electronics from Shasta Community College in 1966. In 1967, he proudly enlisted and served in the US Navy as an electronics technician, serving aboard the USS Barb (SSN-596). Though his military service was cut short due to a medical condition, he was honorably discharged in 1969 at the rank of E5.
Don married the love of his life, Patricia Heide, on June 10, 1967. Together they built a loving home and family. Don began what would become a lifelong career with Picker International. Soon after, he and Pat would welcome their first son, Greg in 1971 and relocate to Tigard, Oregon, in 1974. After a short time in Medford where their second son Kevin was born in 1977, Don and family were transferred to Montana where they would remain.
Don was a gifted and generous man whose talents reached far beyond his professional career. He had a true knack for fixing, building, and improving anything mechanical or electronic. Whether it was radios, machining precision parts, or crafting beautiful woodworking projects, Don’s hands were always busy and his heart was always open to help others. His garage and workshop were more than just spaces—they were sanctuaries of curiosity and creativity, filled with the scent of sawdust, the sound of humming machines, and the spark of innovation.
One of his greatest joys was amateur radio, a passion he formally embraced in 1976 when he earned his first call sign, WB7ETT (later W7MRI in 1997). Through radio, Don formed lasting friendships that spanned nearly five decades. After retiring in 2011, he devoted even more time to the amateur radio community—generously sharing his knowledge, mentoring newcomers, and participating in events such as the Governor’s Cup Race, Field Day, and countless Saturday morning coffee meetups.
Don is survived by his beloved wife of 57 years, Pat Heide; his sons, Kevin Heide and Greg (Jesse) Heide and Grandson James; his mother, Lorene Heide; and his sisters, Peggy (Willie) Heide and Nancy (Garold) Carver. He was preceded in death by his father, John Henry Heide.
Don’s legacy lives on through the countless lives he touched with his kindness, ingenuity, and generosity of spirit. He will be deeply missed, fondly remembered, and forever cherished.

Sorry for your loss.
Terry and Lew Mumford says
We are very sorry for your loss. We loved Don’s stories. He was a man of many talents. He was joyful and kind.
William Erhardt says
Fair winds and following seas my old Navy friend. The good times and we shared over the last 38 years working on Ham Radio equipment, towers, coax, and driving to many mountain tops with fellow hams are memories that will never be forgotten. That type of friendship and comradery lives on forever to those who participated. Thank you for your guidance, patience, and direction over all these years. I will miss you my friend.
John Johnston says
Don was not a good friend; he was a lifelong friend. Countless memories come to mind from years ago in Great Falls, then Helena, and the days and hours spent in other cities. It was always enjoyable to chat about our projects. Bravo-Zulu Don. For the family, I am reminded that the greater the person, unfortunately, the greater the loss. The richness of Don’s life will be with you as will the many friends of all these years.
Tim Hodges says
I first met Don over 40 years ago. He was a good friend that I learned a lot from. RIP.
Lee Marlin Schneider says
Although I did not personally know you, I knew you and Pat through emails. Our shared Marlin roots run deep and that legacy continues on.
Your mama always wrote of how proud of you she was and how you and Pat took such good care of her.. always checking on her well being.
You will be missed by family and friends!
Donald C Paul says
Sorry for the loss of such a wonderful person. I met Don through the RC model airplane club, but we also worked together on some exhibits for Exploration Works. To me he was always such a neat person that you always wanted to be around. I will miss him.
A Helena Amateur Radio beginner says
Generous. Kind. Giving. Mr. Heide had talents and freely shared with those who didn’t.
Case in point, he helped me repair my radio when I could not afford to do so otherwise.
God bless you all.
Mark Zitzka says
When I needed help on electronics, someone at the ham club gave me Don’s name. He helped me, a stranger, and I had the pleasure of visiting with him in his shop many times. I was blessed to get to know him, if only a little. Fellow Navy ETs, I enjoyed this good man. Fair seas, my friend!
James Cooney says
I have a cherished Pratt & Whitney Belt Buckle. It was broken and one day I asked Don what might be the best way to repair it. He took the Buckle and returned it to ma the next day completely repaired. I remember many acts of kindness he performed for others always expecting nothing in return. That’s just the kind of person he was.
Many recipients of his kindness will surely miss him, myself included!
