🎯 Discover one of the most impressive amateur radio set-ups in Tennessee!
The shack of Kurt Meltzer, KC4NX, is a true example of excellence in amateur radio. Set in the beautiful foothills of the Smoky Mountains near Knoxville, this exceptional station represents years of passion, technical expertise and dedication to the hobby. With two towers strategically placed on “Beacon Hill”, an impressive collection of state-of-the-art equipment and active involvement in the local amateur radio community, KC4NX embodies the very best of the passion we share.
📖 The story of KC4NX: an inspiring journey
Hooked at the age of 12
It all began in Illinois when a neighbour who was a radio amateur, Buzz Ross (W9ABA, SK), invited young Kurt to visit his shack. He was hooked straight away. Buzz, an experienced old-school operator, became his mentor and supervised his Novice licence exam.
Rapid progress
At just 14, Kurt passed the General class theory and Morse code exams at the FCC field office in Chicago. A remarkable achievement for such a determined young man.
Twenty years away from HF
Because of antenna restrictions at his QTH while he was raising his family, Kurt concentrated solely on local VHF/UHF activities. He built and operated FM repeaters in the Chicago area, staying active in the hobby despite the constraints.
The move to Tennessee
Moving to Tennessee to escape Chicago's harsh winters marked a decisive turning point. The foothills of the Smoky Mountains finally offered the space needed to build the shack of his dreams. Kurt became self-employed, giving him more flexibility for his radio projects.
Building a legendary shack
He obtained the vanity callsign KC4NX and gradually built one of the most impressive stations in the area: two towers on “Beacon Hill”, a sophisticated underground infrastructure, and active involvement in the Smoky Mountain Amateur Radio Club (president 2016-2017).
💚 A word of gratitude: “I am deeply grateful to my parents (neither of whom were hams) for tolerating my early interest in radio and letting me put up many crude experimental antennas on their house and in the garden, from the age of 13 until I left home at 18. They were wonderful. I also owe endless thanks to my wonderful and understanding wife Sharon for being so patient through all the years spent on repeater projects and now on building this station.” - KC4NX
🏔️ “Beacon Hill”: the ideal location
One of the great assets of the KC4NX QTH is the natural rise behind his house, affectionately named “Beacon Hill” by his wife Sharon. This strategic location offers exceptional conditions for radio communications.
Clear line of sight to the distant horizon in every direction
Well away from neighbouring houses and sources of interference
Perfect elevation for VHF weak signals and HF DX
Breathtaking views over the surrounding Smoky Mountains
📏 Site layout:
- Local VHF tower: halfway up the hill, 30 metres from the house
- Main HF tower: at the top of “Beacon Hill”, 107 metres from the house
- Underground infrastructure: several trenches with surplus coaxial cables (1/2", 7/8" and 1-5/8")
- Remote switching: preamplifiers and coax switches on the hill to optimise performance
“I only wish the previous owner had built this house closer to the top of the hill, because it took a long run of coax to reach the summit!” - KC4NX
